    Composition for a friction material e.g. for a brake pad, of the type containing a fibrous reinforcement, a binder and various additives. …<??>The friction material contains no asbestos, but has properties comparable with asbestos-based materials. The composition contains a thermoset binder including a phenol-formaldehyde resin and making up 20 to 60% by volume of the material. Besides the resin the binder can also include a heat and chemical resistant rubber, but the phenol-formaldehyde resin makes up at least 10% by volume of the composition. …<??>The composition includes a fibre-based reinforcement which makes up to 10 to 35% by volume of the material and consists of a mixture of steel fibres or glass fibres with one or more other non-asbestos inorganic reinforcing materials e.g. steel fibre and mica, or steel fibre and milled glass.

    Copper In example 3, the reinforcing component is a mixture of steel fibers and mica (as in example 1), in example 4, a mixture of steel fibers and crushed E-glass, the latter being a pulverized material consisting of crushed glass fibers. extremely short length. In example 4, a bond includes equal amounts of rubber and resin. The components of the mixture are first mixed, while nitrile rubber is introduced into the mixture as a solution in trichlorethylene with a solids content of 15-20% in the solution and the phenol-formaldehyde resin is introduced as a solution in methylated alcohols with a resin concentration of 70%. The mixture is ground and dried, then molded from it strip in the matrix under pressure. The resulting molded gaskets are fired in a kiln for the purpose of curing the binder. In the case of dynsmometric tests of gaskets from sample of example 3, the coefficient of friction (} J) varies from 0.26 (in cold) to 0.44 (in a hot state), and the coefficient of friction of gaskets from sample of example 4 varies from 0.30 (in the cold) to 0.55 (hot). The wear rate of gaskets from the sample of example 3 is as high as the wear rate of gaskets made of conventional friction materials with a comparable rate of friction. The wear rate of the sample of example 4 is quite acceptable for

The shear strength in the assembly of two gaskets consisting of the sample of example 3 was 16.3.1 and 149.8 kgf / cm, and gaskets from the sample of example 4 - and 156.1 kgf / cm, so when comparing the rubber of the proposed composition with the composition of the prototype, it follows that in terms of wear resistance and friction they are not inferior to the rubber of the prototype. In addition, the proposed composition is much cheaper than the composition of the prototype due to the replacement of asbestos fiber with steel and / or fiberglass.
