PURPOSE:To improve the antifriction property when the material is used in a low temperature area, by impregnating a liquid resin to a C/C composite, and hardening it. CONSTITUTION:A C/C composite is manufactured by using carbon fibers, and after a resol type phenol resin is impregnated to the resultant C/C composite, a heat-treatment is given to harden the resin. As a result, the combination strength within the material is increased, and since a resin cover is formed at the friction surface, not only the primary excellent antifriction property when used in a high temperature area, but also the antifriction property when used in a relatively low temperature area is improved extensively.
