摘要： The invention relates to a friction layer for two opposing friction pieces which may be brought together and apart and which also circulate. At least one friction piece comprises a friction layer rigidly arranged on a support and a medium is found between the friction layer and the corresponding counterpiece to the friction piece. The material components for the material composition of the friction layer made from composite material, further additives and the binding composition of the above, are selected such that the material composition and hence the friction layer have considerable shrinkage properties caused by the heat treatment during the production thereof and shrinkage relative to the material of the support for the friction layer. As a result of the shrinkage process during the heat treatment, a network structure of irregularly distributed, directly interconnected channel-like recesses is embodied in the whole friction layer.
