ABSTRACT:
A method for making a carbon friction product comprises laying a reinforcing support, impregnating it with a binder, heat treating and subsequent machining to form a desired product which is then saturated with pyrocarbon and subjected to heat treatment at graphitization temperature. The reinforcing support is formed by piling up a pack of alternating layers of interwoven carbon fibers and layers of individual elementary fibers, the individual elementary fibers being oriented in such a manner as to partially penetrate the layers of interwoven fibers.
