Abstract (en)
[origin: EP0000840A1] The invention concerns a composition for a friction material, e.g. for a brake lining or clutch facing, 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, which may be based on a phenol-formaldehyde resin, or a heat and chemical resistant rubber, the binder making up 15 to 40% by volume of the material. The fibrous reinforcement is a mixture of an inorganic fibre selected from metal fibres, e.g. steel glass fibre, mineral wools manufactured from slags or naturally occuring rocks such as basalt, silica fibres and ceramic fibres of the alumino silicate type; with at least one organic fibrous material such as wood pulp, jute, sisal, cotton. 70 to 4% by volume of the material consists of the fibrous reinforcement, preferably 50 to 10% by volume. The inorganic fibrous material is the main reinforcement of the friction material, the organic fibrous material providing integrity and strength during manufacture.
