Abstract
Small ceramic particles (e.g., of TiC) are incorporated into fibers. The ceramic particles enhance the friction and/or wear properties of a carbon-carbon composite article made with the impregnated or coated fibers. The impregnated fibers can be, e.g., polyacrylonitrile (PAN) fibers, pitch fibers, and other such fibers as are commonly employed in the manufacture of C-C friction materials. The impregnated fibers can be used to make woven, nonwoven, or random fiber preforms or in other known preform types. Preferred products are brake discs and other components of braking systems. The particles may be included in the fibers by mixing them with the resin employed to make the fibers and/or by applying them to the surfaces of the fibers in a binder.
