Friction disc and process for producing the same

A friction disc, comprising:

• at least one top surface formed as a friction surface;
• a supporting zone;
• a carbon fiber-reinforced ceramic composite material A;
• a material B being different than said material A and exhibiting lower wear and oxidation resistance than said material A;
• and
• between more than 0.1% and 20% of said friction surface being formed of said material B, and a remainder of said friction surface and said supporting zone being formed of said material A.

A friction disc, comprising:

• a friction disc thickness;
• at least one top surface formed as a friction surface;
• a supporting zone;
• a carbon fiber-reinforced ceramic composite material A;
• a material B being different than said material A and exhibiting lower wear and oxidation resistance than said material A;
• at least a part of said friction surface being elements formed of said material B, and a remainder of said friction surface and said supporting zone being formed of said material A;
• and
• said elements formed of said material B having a thickness of less than 100% of said friction disc thickness.
