Abstract
The invention concerns a composition for a friction material, e.g. for a clutch facing, of the type containing a fibrous reinforcement, a binder and various additives. The composition contains a thermoset binder, the binder making up 15 to 40% by volume of the material. The fibrous reinforcement is a mixture of inorganic and organic fibres which makes up about 70 to 33% by volume of the material. The inorganic fibre is selected from metal fibres, glass fibre, mineral wools, silica fibres and ceramic fibres. The organic fibre can be wood pulp, jute, sisal, cotton.
