Abstract:
1. A clutch lining having a friction surface, said clutch lining consisting of fiber-reinforced ceramic materials which consist of short carbon fibers having a weight-average length of from 0.001 mm to 5 mm, an orientation perpendicular to said friction surface of the clutch lining, and a matrix material which fills the intermediate spaces between fibers, which said matrix material is selected from the group consisting of inorganic polymers having a main chain containing no carbon atoms and is made up of atoms selected from the group consisting of aluminum, boron, phosphorus, sulphur, silicon, nitrogen and tin, wherein the inorganic polymers are selected from the group consisting of poly(boronitrides), polyphosphates, polyphosphazenes, poly(siloxanes), poly(sulphazenes) and polysulphides.
