ABSTRACT:
A friction disc, in particular a brake or clutch disc, includes carbon fiber-reinforced ceramic composite material with at least one top surface formed as a friction surface. At least part of the friction surface is formed of a different material, in particular of a carbon-containing material. The different material exhibits lower wear and oxidation resistance than that of the rest of the friction surface and a supporting zone of the friction disc. A visual, audible or mechanical signal is produced under operating conditions due to comparatively greater wear. The signal provides a warning that the service life of the friction disc is being exceeded. A process for producing the friction disc is also provided.
