ABSTRACT:
A carbon/carbon composite is produced by impregnating a primary-formed product consisting essentially of carbon fibers and a carbonized or graphitized matrix with a carboneceous pitch, heat-treating the thus-impregnated primary-formed product under hot isostatic pressing and carbonizing or graphitizing the thus heat-treated primary-formed product.
