Abstract
A friction material which has the temperature capacity of an inorganically-bound material and the softness, minimum attack on the counter material and the noiselessness of an organically-bound material, and which comprises an inorganic binding agent in combination with reinforcing fibers of carbonaceous or carbon-containing material. The volume ratio between the inorganic binding agent and the carbonaceous or carbon-containing reinforcing fibers may vary in the range from 99:1 to 10:90. The reinforcing fibers preferably are fibers of synthetic or natural high polymers, such as polyacrylonitrile, rayon or cellulose fibers, as well as products obtained by the pyrolysis of these high polymers, such as carbon fibers.
