    专利说明:

    The present invention relates to a method for producing a consolidated multilayer semifinished product, comprising the features of the preamble of claim 1 and an apparatus for producing a consolidated multilayer semifinished product having the features of the preamble of claim 11.
    The trend in the design and implementation of consolidated semi-finished products is increasingly in the direction of the targeted introduction of local reinforcement elements. Through the use of such reinforcing elements, especially here are unidirectional tapes or tapes to call, a particularly efficient and cost-effective lightweight construction is possible. Different layers of different materials or with different geometry and / or fiber orientation are arranged on top of each other and thus a layer structure (a semifinished product to be consolidated) is produced. After production of such one to be consolidated
    Semi-finished this is pressurized and supplied heat. By means of such a method, the different layers of the semi-finished product to be consolidated are interconnected and a consolidated semi-finished product is created.
    It is common to speak of a semi-finished product to be consolidated until the semi-finished product to be consolidated has been heated, pressurized and the individual layers joined. Only after the cooling of the semifinished product to be consolidated, at least below the softening temperature, does this apply
    Semifinished product as consolidated. The temperature for the consolidation of a semi-finished product is above the softening temperature of the plastic used. This is for example when using polyamide 6 (short name: PA6) about 240 ° C and polypropylene (short name: PP) about 180 ° C. The pressure to
    Consolidation of the semi-finished product to be consolidated (consolidation pressure) must be selected in such a way that the least possible "fiber swimming" is to be consolidated
    Semifinished product comes, preferably a surface pressure of 0.5 to 10 bar is selected. The
    Steps of heating and applying a pressure to the semifinished product to be consolidated can take place in succession (first application of the pressure and then heating or vice versa) or at least partially overlap in their time sequence.
    The cooling of the semifinished product to a temperature at which the plastic matrix is dimensionally stable takes place at least below the softening temperature and can be carried out actively or passively.
    There are different approaches to fixing the tapes to the base carrier in the various tape-laying methods or layer-building methods. To consolidate the above-described semifinished product to be consolidated, predominantly double-belt presses are currently used which operate continuously or discontinuously. In continuous double-belt presses, the semifinished product to be consolidated is guided between a carrier system (eg PTFE film, metal strip) and passes through a heating and a cooling section. In this case, the plastic matrix of the semifinished product is melted in the heating section and cooled again in the cooling section. The disadvantage here, however, is that only consolidated components can be produced with a constant cross-section with respect to the individual layers.
    In discontinuous systems, the semi-finished product to be consolidated is also packed in a carrier system, but first heated in a designated station and then cooled in a downstream station.
    However, as already described, the load path-oriented design of semi-finished products to be consolidated leads increasingly to layer structures with different wall thicknesses and wall thickness jumps. A consolidation of the same with double-belt press systems is very complicated, since wall thickness jumps can only be displayed with the use of dies. These must be heated in addition and the handling of these is complicated, which has a negative impact on the efficiency of the process.
    Another possibility for producing a consolidated semi-finished product is represented by the use of consolidation presses. Here, a layer structure of a semi-finished product to be consolidated is pressurized, z. B. by at least two tool parts, between which the layer structure is arranged. These at least two tool parts are mostly preheated so that the plastic material is melted and a consolidated semifinished product can be produced by connecting the individual layers to each other. The disadvantage here is that in a secondary process, the tool parts must be heated for consolidation and then have to be cooled again to cool the semi-finished product to be consolidated. This high energy losses are accepted.
    The object of the present invention is to provide a comparison with the prior art simplified and more energy efficient method for producing a consolidated semifinished product.
    This is achieved by a method for producing a multilayer consolidated semifinished product having the features of claim 1 and an apparatus having the features of claim 11. Advantageous embodiments of the invention are defined in the dependent claims.
    The multi-layer semifinished product to be consolidated is also referred to as layer structure. Such a multilayer semifinished product to be consolidated usually consists of at least two layers and may preferably have up to 30 layers. Tapes or fiber-reinforced tapes can be used for these layers, for example. The area of arrangement of the semifinished product to be consolidated is that area of the device which is intended to receive the semifinished product to be consolidated during the consolidation.
    By providing a heat energy required for the heating by means of radiation energy to the semifinished product to be consolidated for connecting the different layers of the semifinished product to be consolidated to form a consolidated semifinished product, thermal energy can be selectively transmitted to the semifinished product to be consolidated. Such a configuration makes it possible to primarily heat the semifinished product to be consolidated without losing energy for heating the surrounding components. Only boundary layers of the layers need to be heated. Possibly. may additionally be provided based on heat conduction heating. In this case, only very thin heat conduction layers must be heated.
    It can preferably be provided that the pressure is exerted by at least one first tool section and a second tool section, which are preferably arranged to be movable relative to one another, onto the semifinished product to be consolidated. These can be z. B. in the form of a base and back plate or in the form of a base plate and a pressure bell be formed.
    It is preferably provided that at least one of the at least two
    Tool sections of the device for applying pressure from a material with a high transmission for the radiation of at least one radiation source is made so that radiant energy is passed through at least one of the at least two tool sections to be consolidated semis. Thus, during the exercise of the consolidation pressure on the semifinished product to be consolidated, it can be heated by means of heat radiation. It can also be provided that each of the at least two tool parts is made of a material with a high transmission for the radiation of the at least one radiation source. Particularly preferred materials here are glasses, quartz glasses or Durangläser. The essential requirements of such a material are a certain pressure stability and a certain transparency for the heat radiation.
    It can be provided that a layer adjoining the semifinished product to be consolidated is heated by radiation energy and that the semifinished product to be consolidated is heated by the adjacent layer due to thermal conduction. So it is possible, for example, that at least one
    Tool section a - preferably having non-stick properties -
    Substrate (non-stick layer) is formed. The non-stick layer can thereby through the
    Radiant energy to be heated so that they heated by heat conduction to be consolidated semi-finished product.
    Generally speaking, it can be provided that the provision of a heat energy required for the heating by means of radiation energy by direct irradiation of the semifinished product to be consolidated or indirectly by irradiation of a layer or plate arranged between the semifinished product to be consolidated and a radiation source emitting the radiation energy.
    It is preferably provided that the radiation energy is generated by means of infrared radiators. Particularly preferably, it is provided that the radiation energy is generated by means of a laser, preferably a solid-state laser.
    It can be provided that the pressure is exerted by the construction of an overpressure in the interior of a bell jar on the arranged on a base plate to be consolidated semi-finished, z. Example by means of a pressure relief line, in particular by means of compressed air or inert gas.
    In a further possible embodiment, it is provided that the semifinished product to be consolidated is closed-at least substantially airtight, preferably by a membrane or a seal-and an overpressure or underpressure is exerted on the semifinished product to be consolidated. Such a membrane can be designed as an adaptable / flexible film. By using negative pressure air inclusions between the individual layers of the semifinished product to be consolidated can be reduced. As a source of negative pressure in this case a vacuum line, for example, with a connected vacuum tank, or vacuum pump serve. In a particularly preferred variant, the counter and the base plate are made so that the intended for receiving the semifinished product to be consolidated interior (arrangement area) is airtight lockable. This can e.g. be supported by a circumferential seal of a preferably elastic material (silicone, Viton, K).
    The membrane is preferably made transparent to the radiation of the radiation source, so that the semifinished product to be consolidated can be irradiated through the membrane and thus heated.
    In an alternative embodiment, however, it is also possible to use a material for the membrane which absorbs the radiation and, by means of heat conduction, emits the heat energy to the semifinished product to be consolidated. Thus, in turn, heat energy is delivered to a directly arranged to be consolidated semifinished component, but in this case the lost heat energy is almost negligible, since a membrane has a small capacity to store heat due to their small thickness or it requires little energy to heat them or to cool. It is also conceivable that a layer is attached to the membrane, which absorbs radiation and has a non-sticking property. Also, the material from which the membrane is made can in turn already have non-stick properties. On the one hand, heat can be generated by the radiant energy, which can be passed on to the semifinished product to be consolidated by heat conduction and, on the other hand, it can be ensured that the semifinished product to be consolidated can be easily separated from the membrane after processing, since the semifinished product to be consolidated is a non-adherent Property opposite the non-stick layer of the membrane has.
    Both base plate and counter plate can be provided with connections and lines for media temperature control.
    It can also be provided that the counter-plate is designed as a membrane or foil. If the counterplate is embodied as a membrane, the device for producing the consolidated semifinished product can optionally also include a tempering plate arranged above the counterplate, which images the geometry of the semifinished product to be consolidated, including the membrane. This is preferably made of a material which has a good thermal conductivity, manufactured and preferably actively tempered.
    A device according to the invention can, for. B. be formed as follows:
    The semifinished product to be consolidated can be deposited on an infrared-transparent base plate. By "infrared transparent" are meant materials which in the radiation spectrum of an infrared radiation source as high as possible
    Have transmissivity.
    Below the base plate, one or more radiation sources are arranged, which can emit infrared radiation through the base plate on the semifinished product to be consolidated in order to heat it in this way. The radiation sources are chosen so that the radiation emitted by them from the to be consolidated
    Semifinished product is absorbed, but only to the smallest extent possible from the
    Baseplate.
    The base plate is coated with a substrate which has non-stick properties, so that the semifinished product to be consolidated is easier to detach after cooling. This layer does not have to be infrared transparent, it can also be used as a heated boundary layer. Thus, depending on the preferred solution
    Semi-finished product mainly heated directly by heat radiation or indirectly by means of heat conduction.
    If wall thickness jumps are present in the semifinished product, it is preferable to additionally have a layer on the base plate which images this geometry. In this case, this layer is designed such that the side or the radiation source (s) facing side absorbs infrared rays to a high degree, but has a low thermal mass to allow energy-efficient heating.
    It may also preferably be provided that for balancing
    Thickness jumps of the multilayer, to be consolidated semi-finished at least one
    Thickness compensation element is provided. Such a thickness compensation element can be designed as a separate component, which is introduced with the multi-layer, to be consolidated component for consolidation. But it is also possible to make the thickness compensation element as part of one of the tool sections. Also, the thickness compensation element can be made of an "infrared transparent" material, have a coating, have a non-stick property, have a high thermal conductivity and / or have a low thermal mass. It may preferably be provided that the
    Thickness compensation element is movable together with one of the tool sections or separately from this.
    It is provided a back plate, which also made of an infrared transparent
    Be made of material and can be made with the same characteristics as the base plate. Optionally, one or more radiation sources are arranged above the counterplate.
    In another embodiment, the backplate may also be embodied as an imageable / flexible film or membrane. This film / membrane is preferably also formed infrared-transparent, so that the semifinished product to be consolidated can also be heated from the top by means of thermal radiation.
    In an alternative embodiment of the invention, however, it is also possible to use a material which absorbs the infrared radiation and, by means of heat conduction, emits the heat energy to the semifinished product to be consolidated.
    Of course, a combination can be used such. B. an infrared transparent film with an infrared-absorbing non-stick layer.
    Base plate and counter plate are preferably arranged axially movable relative to each other, so that an opening and closing movement can be performed and can be applied by pressing the consolidation pressure on a laid down on the base plate to be consolidated semi-finished.
    In a preferred embodiment of the invention, the base plate is stationary and the counter-plate is designed to be axially movable. In an alternative embodiment, the counter plate is stationary and the base plate is designed to be axially movable. Alternatively, both plates can be designed to be movable relative to each other.
    A method for consolidating a semifinished product with an above-described
    Device is z. As follows:
    After the semifinished product to be consolidated has been deposited on the base plate, the counter and base plates are moved relative to one another and the device is thus moved into the closed state. The closing movement can be done by moving the counter-plate, the base plate or both plates.
    Preferably, a defined pressure is exerted on the semifinished product to be consolidated with the closing movement. This pressure is used to fix the semi-finished product to be consolidated and further the purpose that the individual layers of the semi-finished product to be consolidated are in contact with each other almost completely. This pressure can be increased until a consolidation pressure is achieved.
    Optionally, a negative pressure in the interior is created after closing, which regulates the contact pressure on the one hand and further supports the consolidation. In the regulation or control of the contact pressure, combinations are also possible, so that the contact pressure consists of a negative pressure and an externally active force.
    If the semifinished product to be consolidated is fixed between the two plates and the contact surfaces of the individual layers are at least partially in contact with one another, thermal energy is introduced into the semifinished product to be consolidated either directly or indirectly by means of thermal radiation. This can be unilateral or bilateral.
    The heating itself is preferably controlled. In this case, the interface temperature between the base plate and the semifinished product or counterplate and tool to be consolidated is preferably measured optically. Alternatively or additionally, the temperature of the heat conducting layer or of the semifinished product to be consolidated itself can be measured. On the basis of this at least one temperature, the control of the at least one radiation source takes place. Preferably, the temperature is measured at several points and the radiation source (s) is or are regulated by several control circuits.
    The control temperature is the material of the plastic matrix of the to be consolidated
    Semi-finished and is located above the
    Plastic softening temperature of the plastic. Particularly preferred is a
    Control temperature, which is above the melting point of the plastic. To
    Reaching the control temperature, the temperature is maintained for a certain time. This time is adjustable and depends on the thickness of the semifinished product to be consolidated.
    After the thermoplastic matrix of the semifinished product to be consolidated has been at least partially melted, it is cooled to the extent that it is dimensionally stable and thus demoldable. When using an active cooling, the introduction of the cooling power preferably takes place on one side and can be carried out in various ways, depending on the embodiment of the device:
    Are base plate and counter plate dimensionally stable, so they can be used even to cool the semifinished product. In order to support the heat dissipation, these can also be actively cooled.
    In a further variant, only a foil / membrane is designed as a counterplate.
    This side can be actively cooled by means of convection support (eg blower).
    If a foil or a membrane is used as counterplate, a separate tempering plate can be placed on it for cooling.
    This tempering plate can the geometry of the semifinished product plus the wall thickness of the
    Foil / membrane included. The tempering plate is preferably made of a material which has a very good heat conduction, so that the heat energy can be withdrawn from the semifinished product quickly. In addition, this plate can be actively tempered. In this preferred variant, the heat energy is thus absorbed mainly by the temperature control. Because in this case the
    Tempering plate absorbs a higher amount of heat than the base plate, can be spoken of a one-sided cooling here. During cooling, additional pressure should be exerted on the semi-finished product. This pressure is preferably adjustable.
    Once a defined temperature has been reached, the pressure can be released. The opening movement can be done by moving the counter-plate, the base plate or both.
    The finished consolidated semi-finished product can be removed and a new, not yet consolidated semi-finished product is deposited.
    The at least one radiation source can be arranged to be movable.
    Further advantages and details of the invention will become apparent from the figures and the associated description of the figures. Show:
    1 shows an inventive device for producing a consolidated semi-finished product, wherein a membrane is used as a counter-plate,
    2 shows a device according to the invention for producing a consolidated semifinished product with active cooling device,
    3 shows a device according to the invention for producing a consolidated semi-finished product with a rigid base plate and counter plate as well as two-sided heating, and
    4 shows a device according to the invention for producing a consolidated semifinished product of different wall thicknesses.
    FIG. 1 shows a device according to the invention for producing a consolidated semifinished product 5. In this case, a multi-layer semifinished product 1 to be consolidated is arranged on a base plate 2. In order to exert a pressure on the semifinished product 1 to be consolidated, a membrane 3 is placed over the multilayer semifinished product 1 to be consolidated. By, for example, by means not shown, a negative pressure between the diaphragm 3 and the base plate 2 is generated, there is a compressive force on the semi-finished product to be consolidated 1. However, it can also be provided that the membrane 3 is rigid and by this a force on the multilayered semifinished products 1 to be consolidated can be exercised. In this embodiment, therefore, the area between the diaphragm 3 and the
    Base plate 2 (acts here as the first tool section) as an arrangement area for the semifinished product 1 to be consolidated. The membrane 3 acts here as a second tool section and counter plate.
    Radiation energy 4 can be introduced directly or indirectly into the multilayer semifinished product 1 to be consolidated by the radiation sources 4. It can be provided that the base plate 2 made of a glass material, a Duranglas or a
    Quartz glass is made so that it has a high transmission for the radiation energy which is generated by the arranged below the base plate 2 radiation source 4. The radiation energy which is generated by the radiation source 4 arranged below the base plate 2 can thus directly irradiate the semifinished product 1 to be consolidated coming from below and thereby heat it. The radiation sources 4 may be movably arranged with respect to the semifinished product 1 to be consolidated.
    It is possible that the membrane 3 made of a material with a high
    Transmission is made for the radiant energy, which is due to the
    Radiation source 4 is generated. Thus, from above, the multilayer semifinished product 1 to be consolidated can be heated directly by the radiant energy. But it is also possible that the membrane 3 is made of a material which has no or no high transmission for the radiant energy. Then, the membrane 3 itself is heated by the radiant energy and can by thermal conductivity of this heat energy to the multilayer, to be consolidated
    Forward semi-finished product 1 (indirect heating).
    Fig. 2 shows an apparatus for producing a consolidated semifinished product 5 (as shown in Fig. 1) after heating during cooling. In this case, a temperature control plate 6 can be placed on the multi-layer semifinished product 1 to be consolidated. It can be provided that the semifinished product 1 to be consolidated is cooled only by the temperature of the temperature-control plate 6 present during placement. The tempering plate 6 can additionally be cooled internally or externally by a cooling medium. Furthermore, it can also be provided that the semifinished product 1 to be consolidated, the temperature control plate 6, the base plate 2 or even the membrane 3 are cooled by air cooling.
    FIG. 3 shows a further apparatus for producing a consolidated multilayer semifinished product 5. Again, a multi-layer semifinished product 1 to be consolidated is placed on a base plate 2 here. The base plate 2 is made of a material with a high transmission for radiant energy, which makes it possible that radiation energy - generated by the radiation sources 4 - passes directly to the semifinished product 1 to be consolidated.
    In this embodiment, the pressure on the semifinished product 1 to be consolidated is exerted by a counter-plate 7 (acting as a second tool portion) which is movable relative to the base plate 2. Also, the counter-plate 7 is made in this embodiment of a material having a high transmission for radiant energy, thereby allowing that generated by the radiation source 4 radiant energy through the counter-plate 7 passes through to be consolidated semis 1 and this can heat directly. The base plate 2 can be supported by cross struts 8 as shown. As a result, a higher pressure load of the base plate 2 is allowed. Between base plate 2 and counter plate 7 seals 9 may be arranged. These seals 9 are arranged around the semifinished product 1 to be consolidated between the counterplate 7 and the baseplate 2 (here in the form of a single circumferential seal 9), so that a substantially airtight sealing of the receiving region is possible for the multilayer semifinished product 1 to be consolidated. It can also be here, as in Fig. 1, a negative pressure generated, which allows an additional pressure build-up on the semifinished product 1 to be consolidated.
    Fig. 4 shows substantially the same apparatus for producing a consolidated semifinished product 5 as Fig. 3, but are additional here
    Thick compensation elements 10 provided. The thickness compensation elements 10 are inserted to compensate for this thickness jump of the semifinished product 1 to be consolidated with respect to the counter-plate 7 or the base plate 2. However, the thickness compensation elements 10 are preferably part of the tool sections. The
    Thickness compensation elements 10 may be made of a material having a high
    Be made transmission. They can also be made of a material with a higher thermal conductivity, so that they convert the radiation energy generated by the radiation source 4 into heat and forward by thermal conductivity to the semifinished product 1 to be consolidated.
