Abstract
A carbon brake disc has its torque transmitting formations (keyways or keys) reinforced by filament reinforced carbon inserts which are preferably located, and may be bonded, in cut-out areas of the disc periphery. The formations are formed by a separate series of operations from those used to form the remainder of the friction members such as by application of a filimentary reinforcement of carbonized cloth, textile tape, random textile fibers or boron fibers.
