    [001] The present invention relates to a method for producing a composite material composed of metal and plastic to form a hybrid plastic-metal component.
    [002] In such a method known from JP 2014-051041 A, in a first procedural step, macroscopic and/or microscopic notch grooves are introduced by means of short-pulse laser radiation on the metal surface in order to texturize it to improve the adhesion of the metallic surface and at least one plastic component, the concave-shaped opening region of these slots notched in the plan view and in the longitudinal cross-section thereof aiming to have a precisely defined geometrically repeatable shape. Constantly repetitive defined shapes such as a circular shape, the shape of a ginkgo tree leaf, the shape of a boomerang, an elliptical shape, a frame shape, a polygonal shape or the like are specified for the opening region of the grooves to be introduced into the metal surface in its plan view and a triangular shape, a rectangular shape or a trapezoid shape for the longitudinal view of the grooves. In a second process step, the precisely formed grooves in the metal surface are then at least partially filled with the at least one plastic component, in such a way that an improved adhesion between the latter and the grooves in the metal surface is obtained.
    [003] A method for producing a composite body composed of at least one metallic component to be prefabricated and at least one plastic component is also known from document DE 10 2011 100 449.5 A1 where, for a surface of the metallic component that must be placed in contact with the plastic component and in which a serrated arrangement with a multiplicity of serrated elements arranged spaced apart from each other must be printed, the profile of the individual serrated elements of the serrated arrangement must be curved away from the surface of the metal component and/ or its number and/or its distribution within the toothed arrangement and/or its position in space (x, y, z coordinates) and/or its area and/or its surface structure and/or the surface roughness is determined by means of numerical simulation oriented towards the flow of forces according to the static and/or dynamic forces, calculated in advance, acting on the composite body at each connection of the composite body to be r produced in a form-fitting manner, and then the multiplicity of toothed elements of the toothed arrangement is printed on the surface of the metallic component, arranged and oriented apart from each other in a profiled manner corresponding to the numerical simulation, and thereafter each toothed element is curved in around the bending edge away from the surface of the metallic component and to its position oriented to the flow of forces in the predetermined space by means of numerical simulation, and the metallic component is then closely connected to the shape of the plastic component to form the body. composite. The metal component, from which the multiplicity of toothed elements of the toothed arrangement is curved outward, is then fixed to an injection molding tool and the plastic component of the composite body is injected in a traditional injection molding process onto the surface of the component. metallic of which the multiplicity of toothed elements is curved outwards, where each toothed element of the toothed arrangement is embedded in the plastic of the plastic component injected into the metallic component in its position oriented to the flow of forces in the predetermined space by means of numerical simulation and is firmly anchored to it when the plastic of the plastic component solidifies.
    [004] The document DE 10 2007 023 418 B4 describes a method for texturing the surfaces of components, in particular metal, plastic or ceramic, for the improved adhesion of thermally sprayed layers thermally deposited thereon, as the surface is textured thus forming microscopic grooves, where molded depressions with inclination angles in the range of 20° to 80° are introduced into the surface by means of pulsed laser beams, said molded depressions being dimensioned so that at least one of the edges of the molded depressions form a groove with respect to the metal surface, where the surface is repeatedly treated with pulsed laser beams at least in sections, said laser beams having different directional angles, different inclination angles and/or different laser energies. It is described in that document that, advantageously for the quality of the coating, the sprayed jet must be guided over the surface with the same inclination as the molded depressions. To do this, the molded depressions must be formed in the same direction parallel to only one edge groove relative to the surface. The deeper the molded depressions, the more accurate is, therefore, a suitable coincident angle of the spray jet to be used. Angle adjustment tolerances decrease correspondingly. A spray jet not properly selected can therefore lead to incomplete filling of the molded depressions, which has a negative effect or reduces the bond strength of the spray layer.
    [005] Furthermore, a method for texturing metal surfaces to improve the adhesion of thermally sprayed layers thereon is known from DE 10 2006 004 769 A1. Here, recesses or depressions are introduced into the surface in a metal-removal treatment in a first procedural step, so that the metal projecting from the surface forms vertical microstructures, in particular projections, grooves, protuberances or teeth, where these microstructures are modified by formation and/or rupture in at least a second process step, such that a substantial proportion of the structures constitute grooves with respect to the surface.
    [006] A method for producing a composite component, in particular for automotive applications, is disclosed in DE 10 2008 040 782 A1 comprising at least a first component with a first contact surface and at least one second component with a second surface of contact adjacent to the first contact surface, where the surface structure is generated by means of a laser on the first contact surface of the first component, so that said surface structure comprises a microstructure superimposed by a nanostructure. After surface texturing of the first contact surface of the first component, the latter is connected to the second component, which is made of plastic material, in particular of a thermoplastic material, by encapsulating the first component with the second component in a manner adjusted to the form at least in the sections.
    [007] Furthermore, a control box module made of a hybrid metal-plastic composite for an internal combustion engine is known from DE 10 2011 111 745 A1, said control box module comprising at least one metallic insert, wherein the rib structure comprises injection molded reinforcing ribs made of a thermoplastic plastic comprising short fibers of a reinforcing material with a volume ratio of at least 305.
    [008] Finally, a method to produce a composite part is known through document DE 10 2010 055 824 A1, said composite part being reinforced by hollow profile body, where the following procedural steps are carried out: 1. preparation of a profile body, 2. inserting the profile body into a cavity of an injection molding tool, 3. forming the composite component by injection of plastic material in the cavity, where the hollow profile body is supported during injection by a means of reinforcement in the internal volume of the profile hollow body, 4. curing of the injected plastic material.
    [009] The present invention is based on a new problem in offering a method of the type mentioned at the beginning, with which a robust plastic-metal hybrid component with a high stability under load can be produced, which is extremely non-critical in the which concerns the surface purity of the metal before processing and is stable with respect to loads due to temperature variation and corrosion. In particular, it must be ensured that, in order to optimize the bond strength of the hybrid plastic-metal component to be joined in injection molding the at least one plastic component to the textured metal surface, premature settling of the former is prevented and a Maximum adhesion stability of the at least one plastic component to the textured metal surface is guaranteed.
    [0010] According to the invention, the problem is solved by all the aspects of the method according to claim 1. Improvements to the method according to the invention are described in the sub-claims.
    [0011] According to the invention, to improve the adhesion of the metal surface and at least one plastic component, stochastic random macroscopic and/or microscopic grooves are introduced by means of short pulsed laser radiation into the metal surface in order to texturize it, each of said grooves being at least partially filled with the at least one plastic component in an injection molding process, so that said plastic component engages macroscopic and/or microscopic grooves, where, after the surface metal is textured and before and/or during the injection molding process for the at least one plastic component, at least the textured surface of the metal is heated to a temperature that, during processing, varies in the range from ambient temperature to 100° C above the processing temperature of the at least one plastic component.
    [0012] To generate the macroscopic grooves of the metal surface by means of short pulsed laser radiation, a scanner with a focal length adapted from the optics of the optical scanner and a beam guide is preferably used. The scanner and the metallic surface to be textured can be continuously shifted at a predetermined speed relative to each other, where the movement of the scanner is superimposed by an axial movement of a robot or of the axial system or of a coordinate system of the object a be processed, so that the optical scanner guides the laser beam in a continuous circuit over the metallic surface in its working field and a uniform roughness (texturing) is generated with a continuous relative motion over the entire metallic surface.
    [0013] The temperature to which the textured surface of the metal is heated preferably ranges from a temperature less than 100°C to the processing temperature of at least one plastic component.
    [0014] The heating of the textured metallic surface of the metal can occur up to a temperature that is greater than the glass transition temperature, preferably in the region of the latter in the case of thermoplastics.
    [0015] The temperature to which at least the textured surface of the metal is heated is preferably selected depending on parameters such as process duration, flux viscosity and fineness and depth of roughness (texturing) of the metal surface.
    [0016] In a preferred embodiment of the method according to the invention, heating of the metal can take place in an injection molding tool, and preferably inductively. As a result of the inductive heating of the metal side of the composite material in the injection molding tool, the temperature can be regulated very precisely and even heating of the metal side of the composite material can be obtained to ensure maximum processability.
    [0017] The heating of the metallic side of the composite material, however, can also occur outside the injection molding tool, for example, in a furnace, which in the method according to the invention allows the use of a molding tool by injection is much simpler, as long as there is a temporally direct sequence of steps in the method. The use of a comparatively low cost injection molding tool is also possible in the case of heating the metallic side of the composite material using temperature regulation in a directed way by means of water, oil or gas in an IHF process (forming process high internal pressure (internal high-pressure forming)).
    [0018] The temperature of the metallic side of the composite material to be obtained by variable temperature regulation is dependent on the properties of the selected plastic component. Therefore, when thermoset plastics are used for the plastic component, heating at least of the textured metallic surfaces of the metal can preferably take place at a temperature that is above the glass transition temperature of the plastic component and below the maximum processing temperature of the plastic component of the plastic-metal hybrid component during injection molding onto the textured metal surface and which is selected depending on process parameters such as injection molding duration, flux viscosity, and metal surface roughness (texturing) fineness and depth . The decisive factor is that the grooves in the textured metal surface are at least partially filled with the plastic component.
    [0019] As plastic components, both thermoplastically processable molding compounds and subsequent fixation molding compounds such as thermosetting plastics and also multi-component systems are used, which can be modified in terms of their nature and composition, adapted to the requirements in the application area given of the hybrid plastic-metal component produced in accordance with the invention. A lower viscosity of a polymeric component or a corresponding resin system is advantageous for filling the cavities of the textured metal surface.
    [0020] Possible modifications of the composition of polymeric components include the chemical structure of the polymer molecules. Thermoplastic polymers such as polyamides, polyesters, polyacetals, polybutylene terephthalate and polyolefins such as polypropylene or polyethylene or mixtures thereof or polyamides such as polyamide 6 or polyamide 6.6 or polyphenylene oxide or polyether imide are preferably selected as thermoplastics. Partially crystalline polyamide 66 proved to be advantageous because of the combination of high thermal deformation resistance and flowability.
    [0021] Possible combinations of the composition of the plastic component also include the area of fillers and reinforcement materials, in particular fibrous and platelet-like reinforcement materials, and also the area of additional additives, in particular in view of a modification of the adhesion of the plastic or at least one plastic component on the textured metal surface.
    [0022] In the area of fillers and reinforcement materials, components that reduce the coefficient of expansion of the length of the plastic component and reduce the stresses in the interface region of the composite material caused by a temperature variation are particularly advantageous. Glass fibers, carbon fibers or aramid fibers are preferably used as fibers to reinforce the at least one plastic component. Polymer-based reinforcement systems such as aramid fibers, which have a negative thermal expansion coefficient along the fiber orientation, prove particularly advantageous in this regard.
    [0023] In the method according to the invention, plastic components without reinforcing fibres, with relatively short reinforcing fibres, for example with a fiber length of less than 1 mm, preferably less than 0.4 mm, can be used , or short glass fibers before the injection molding process, and/or with relatively long reinforcing fibers, for example with a fiber length in the range of 1-30 mm before the injection molding process. Thermoplastics, thermoset plastics and elastomeric plastics can be used here, where technical plastics such as polypropylene or polyamide which are reinforced with fibers are preferably used.
    [0024] The filling of the metal surface texturing cavities during injection molding with fiber reinforced plastic ensures a high load-bearing capacity of the composite material and, surprisingly, it is possible to obtain excellent coupling of the glass fiber reinforced plastic component , in particular in the macroscopic and/or microscopic grooves of the textured metal surface. By means of a partially evacuated injection molding tool, it is possible to obtain complete filling of the metal surface texturing cavities which are introduced into the metal surface.
    [0025] When steel is used as a metal and highly reinforced thermoplastic plastic as a plastic component, ie, partially crystalline polyamide 66, the textured steel surface is heated prior to the injection molding process with the highly reinforced thermoplastic plastic up to a temperature in the range of 100°C below the flux temperature to the flux temperature during processing.
    [0026] Prior to injection molding, the at least one plastic component is preferably mixed with additives to increase its bond strength to the heated, textured metal surface.
    [0027] The production of the composite plastic-metal hybrid component material is preferably simulated numerically depending on the process parameters, heating at least the textured metal surface to a temperature, injection molding process duration, flux viscosity and fineness and depth of roughness (texturing) of the metallic surface.
    [0028] If aluminum is used as a metal in the composite material and, after texturing the aluminum surface, the aluminum component is formed under high internal pressure conditions in a high internal pressure combined with fur injection molding process minus one plastic component, the aluminum forming heat can be used to heat the textured aluminum surface in the injection molding process with the at least one plastic component.
    [0029] The hybrid plastic-metal component producible according to the invention is preferably used as a structural component with a relatively high degree of lightweight construction in the manufacture of cars or in the manufacture of other means of transport or for electronic devices.
    [0030] The main advantages of the invention are the creation of a robust connection between plastic and metal with high stability under load, which is extremely non-critical in terms of the purity of the metal surface before processing. The composite material proves to be extremely stable in thermal fatigue tests and in corrosion tests.
    [0031] As a result of the inductive heating of the metallic side of the composite material in the injection molding tool, the heating temperature of the metallic surface can be regulated very precisely and uniformly, and as a result a high level of stability of the process.
    [0032] As a result of heating the metallic side of the composite material outside the injection molding tool, the latter can be implemented much more simply, provided that the method steps of the method according to the invention are implemented in a temporally close sequence.
    [0033] In addition, directionally adapted structures with a macroscopic texturing depth in the range of 100 μm to 1 mm are possible with stochastic random microscopic roughness shapes, and as a result the ideal plastic and metal engagement in the subsequent injection molding process.
    [0034] In particular, the method according to the invention ensures that, for the optimization of the bond strength of the hybrid plastic-metal component to be joined in the injection molding process with at least one plastic component, the premature laying of this the latter is prevented, with at least partial filling of the grooves with excellent engagement of the at least one plastic component in the macroscopic and/or microscopic grooves of the textured metal surface is obtained and the maximum bond strength of the at least one plastic component is guaranteed to the surface Textured metallic.
    [0035] The method according to the invention guarantees the production of a composite material composed of metal and plastic to form a hybrid plastic-metal component, which continues to have excellent durability in the context of the presence of temperature variation and/or after corrosion.
    [0036] The invention will now be explained with reference to the figures in the drawings. In these figures:

    [0047] The invention will now be explained with reference to the figures in the drawings. In the latter:
    [0048] Figures 1 and 2 each show a microscopic representation of a laser texturing of the metallic surface of a first and a second metal-polymer composites to be produced in each case with variable spacing and texturing depths laser, which was generated to prepare the joint area of the respective metal-polymer composite. As shown in an REM image according to figure 3, laser texturing is applied in a way that it extends two-dimensionally over the metallic surface 3 for its texturing, where the size of the area is dimensioned according to the forces to be transferred by the respective metal-polymer composite to be produced. Laser texturing can occur by means of short pulsed laser radiation, where - as can be clearly seen in figures 1 to 3 - random macroscopic and/or microscopic stochastic grooves are introduced into the metallic surface to texturize the metallic surface. During the joining of the metal-polymer composite in an injection molding process, the macroscopic and/or microscopic grooves are at least partially filled with the polymeric component, so that an engagement of the latter in the macroscopic and/or microscopic grooves occurs for the marked improvement in terms of adhesion of the metallic surface and the polymeric component.
    [0049] A CT cross-sectional image of the joint area of a composite of aluminum/fiber-reinforced polyamide can be seen in Fig. 4, where the aluminum with the laser-textured surface and grooves and the fiber-reinforced polyamide of glass material, with which the grooves are filled, are shown above. As laser texturing of the aluminum surface cannot be fully ventilated during the injection molding process, small residual parts are left unfilled (shown in dark in the representation), which, however, can be avoided by using a tool. of partially evacuated injection molding.
    [0050] Figure 5 shows a detailed image of the joint area of a composite steel/polyamide reinforced with fiberglass, where the metal is marked in dark at the bottom, the polyamide in medium gray at the top, the fibers of glass in the latter in vivid gray and the regions of the composite metal/fiberglass-reinforced polyamide unfilled with fiberglass-reinforced polyamide in white. Here too, before joining the fiberglass-reinforced metal/polyamide composite in the injection molding process, stochastic random macroscopic and/or microscopic grooves are introduced by short-pulse laser radiation into the metal surface. order to texture it. To reinforce the polyamide, it is possible to use short fibers with a length of 1-2 mm before the injection molding process and/or long glass fibers with lengths of up to 30 mm before the injection molding process. With the help of a partially evacuated injection molding tool, it is possible to obtain complete filling of the laser texturing of the textured metal surface with the fiberglass reinforced polyamide, so that a very high load-bearing capacity of the composite is guaranteed. fiberglass reinforced metal/polyamide.
    [0051] Complete filling of the laser texturing of the textured metal surface with glass fiber reinforced polyamide can be achieved with the help of a partially evacuated injection molding tool, so that a very high load-bearing capacity of the composite is guaranteed made of metal/fiberglass reinforced polyamide.
    [0052] Similarly, Fig. 6 shows a detailed image of the joint area of a composite steel/fiberglass reinforced polyamide, where the steel is shown below and the fiberglass reinforced polyamide material above and the grooves of the laser textured steel surface, filled by the latter, are shown. For filling the grooves and cavities of the laser textured steel surface in the injection molding process, it is necessary to prevent premature settling of the plastic material, especially when using highly viscous plastics. It is therefore necessary to heat, for example by induction, the textured steel surface by means of short pulse radiation before the bonding process or during the bonding process.
    [0053] For example, a steel temperature of approximately 250°C has proved very well suited in a combination of steel with highly reinforced polyamide 66, where the temperature can range from approximately 50°C lower or 30°C higher depending on the type of polyamide used, such as, for example, suitable for high temperatures, impact resistant etc.
    [0054] Fig. 7 shows a photographic image of a hybrid plastic-metal component as a test body after a destructive test, where the 5 mm base width of the plastic component can be seen on a metal plate measuring 40 mm x 70 mm. If, for example, a high internal pressure formed aluminum component is connected to a plastic component, the aluminum forming heat can be used in an integrated joining process so that additional heating is not required before the unity.
    [0055] With reference to the test body, it has been shown that the loads and reinforcement materials of the plastic components used, which due to their nature can penetrate into the cavities of the laser textured metal surface, can contribute to a transfer of forces improved in proximity to the composite interface.
    [0056] To prevent corrosion of the plastic-metal hybrid component joint area, an elastomeric material frame surrounding the joint area can be injected first when using a two-component injection molding process, and thereafter the thermoplastic or thermosetting plastic component is deposited directly onto the laser textured metal surface of the joint area, whereby a load-stable composite is produced. Alternatively, the elastomeric frame can also be deposited, after production of the composite, around the latter by a suitable process such as, for example, injection molding for sealing purposes.
    [0057] A diagrammatic representation of an optical scanner during its movement is shown in Fig. 8, said scanner being used with an adapted focal length of the optical scanner and a beam guide for the stochastic random introduction of macroscopic grooves and /or microscopic on the metallic surface for texturing it by means of short-pulse laser radiation.
    [0058] The mechanical structure of the optical scanner 1 as such is known. According to the method according to the invention, the scanner 2 is continuously displaced at a predetermined speed (arrow v) in relation to the metallic surface 3 to be textured, where its movement is at the same time superimposed by an axial movement of a robot ( not shown). The optical scanner 1 guides the laser beam 4 in a continuous circuit over the metallic surface in its working field (x, y) 5, where a uniform stochastic roughness (texturing) is generated continuously with continuous relative motion over the entire surface metallic to be textured.
    [0059] As can be seen in fig. 8, a laser beam 4 emitted from a laser light cable 6 of the optical scanner 1 is guided via a collimator 7, the laser optics and a deflector mirror 8 arranged downstream of the latter in the beam direction to a system of A galvanometric scan comprising a 9 x-axis scanner and a 10 y-axis scanner and is deflected from the latter via a flat-field lens 11 arranged downstream in the beamguide in the working field of the metallic surface to be textured. When optical scanner 1 is installed on the arm of a robot, the joint area to be textured can be moved away with the help of a spacing control.
    [0060] Fig. 9 illustrates that the optical scanner performs a predetermined relative movement in relation to the surface of the piece to be textured, where, as can be seen in Fig. 9, the optical scanner guides the laser beam in a continuous circuit over a closed structure of the part surface in its working field (x, y). By superimposing the two movements, desired stochastic structural shapes of the metallic surface to be textured can be generated, which are coincident with the subsequent loading direction, with different depths. The format and depth of the generated laser texturing can be defined by changing the orientation (shape) and/or speed of the beam movement and by simultaneously adapting the laser parameters such as, for example, power and/or repetition rate . Texturing depths from various 100 μm up to 1 mm are possible. Adaptation of the injection molding process to the nature of the bonding partner and the specific load profile is therefore possible.
    [0061] Fig. 10 illustrates the possibilities of an optimization of the bond strength of a composite material composed of metal and plastic to be produced according to the invention to form a hybrid plastic-metal component. According to the test specifications of a test station (block A) of the composite material to be produced, a change in the texture of the metal (block B) as well as a modification of the plastic granulate used (block C) of the respective joining partner corresponding, metallic or plastic component, is possible by means of a so-called respective external optimization (direction arrow I and II). Furthermore, according to the test specifications of the composite material to be produced (block A), after the introduction (direction arrow III) of the metal component with the laser textured surface (block B) into an injection molding tool (block D) for its heating (block E) inside the latter, and after the introduction (arrow IV) of the plastic granulate (block C) in the injection molding tool (block D) for the purpose of producing a flux ( block F) of plastic granulate prior to joining the two joining partners in an injection molding process (block G), a change in metal temperature (V direction arrow) or a change in flux temperature (VI direction arrow ) is possible by means of a respective corresponding internal optimization, so that the injection molding process (block G) is started after the introduction of optimized values from the heating of the metallic component (direction arrow VII) and the flux of the plastic component (direction arrow VIII) and the composite material is produced with an optimized bond strength, said composite material being removed from the injection molding tool (block D) and fed again (direction arrow IX) into the test station (block A).
