ABSTRACT:
A carbon fiber reinforced carbon of the present invention is composed of a sintered body comprising precursor carbonaceous fiber and self-sintering carbonaceous powder with the precursor carbonaceous fiber buried therein. Since the precursor carbonaceous fiber working as a reinforcement and the self-sintering carbonaceous powder working as a binder come to have substantially the same physical properties (strength, shrinkage rate and the like), the boudary adhesion between them improves, thereby giving the sintered body high strength and excellent abrasion resistance. When the precursor carbonaceous fiber is subjected to a surface treatment using a viscous material, the wettability of the surface of the precursor carbonaceous fiber increases, thereby further improving the boundary adhesion between the precursor carbonaceous fiber and the self-sintering precursor carbonaceous powder.
