Patent Abstract

The disk (10) has a friction ring (12) comprising two friction ring halves (14, 16), and a carrier part (18) arranged between the friction ring halves. The carrier part is connected with the friction ring halves over joining surfaces (20-26) in a material-fit manner. One of the joining surfaces in a portion is machined by a surface machining process by roughening the joining surfaces. The friction ring halves are formed from metal matrix composite material. The carrier part is connected with the friction ring halves by casting. An independent claim is also included for a method for manufacturing a brake disk.
