Abstract

Composite which contains reinforcing fibers comprising carbon and whose matrix comprises silicon carbide, silicon and copper, with the mass fraction of copper in the composite being up to 55%, processes for producing it, in particular by liquid infiltration of C/C intermediate bodies with melts comprising Si and/or Cu and Si, and also its use as friction lining in a friction pairing with ceramic brake discs or clutch discs comprising C/SiC.
