FRICTION OR SLIP BODY COMPRISING COMPOSITE MATERIALS, REINFORCED WITH FIBRE BUNDLES AND CONTAINING A CERAMIC MATRIX

摘要

The invention relates to a friction or slip body which consists of at least two composite materials, reinforced with fibre bundles and containing a ceramic matrix. A first composite material acts as a friction layer, forming the exterior of the slip body and a second composite material forms a suppor t body which is in surface contact with the friction layer. The length of the fibre bundles of the friction layer is significantly shorter than the length of the fibre bundles of the support body. The bundles of fibres of the friction layer have a defined orientation that is perpendicular to the surface. The surface of the friction layer essentially has only small areas of a maximum 1.2 mm diameter of exposed carbon and the total proportion of exposed carbon on the surface is at maximum 35 %. The surface has a structur e of extremely fine fissures and the friction layer has practically no tension close to the surface.
