Abstract

Friction members are composed of a ceramic composite material. The friction members can be used for motor vehicles as a clutch disk for friction clutches, for transmitting motive power, or as a brake disk. A friction zone of the friction member is composed of ceramic, in particular of Si and SiC. A core zone of the friction member is made from fiber-reinforced C/SiC, in particular of long fiber woven fabric-reinforced and short fiber-reinforced C/SiC.
