Abstract
A two piece brake disc includes an outer ring shaped member and an inner ring shaped member disposed concentrically within and joined to the outer member. One of the members comprises a structural member for mounting the disc with the other member comprising a wear member having one or more frictional surfaces and being replaceable because of the two piece construction. The members are essentially all-carbon composites which may differ chemically from one another such as through use of additives in the structural member to increase its oxidation resistance. The all-carbon composites may include carbon fibers with at least some of the fibers in the structural member being longer and circularly oriented to provide portions of the structural member with added strength.
