    摘要： 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.

    摘要： Disclosed is a sliding member having a predetermined shape and including: a sintered body obtained by sintering a composite body including: preliminary carbonized carbonaceous fiber; inorganic powder or inorganic fiber; and self-sintering carbonaceous powder with the preliminarily carbonized carbonaceous fiber and the inorganic powder or the inorganic fiber buried therein. The sliding member has a high and stable friction coefficient (.mu.), high strength, excellent abrasion resistance, and is manufacturable at a low cost. Further, the friction coefficient (.mu.) and the other properties of the sliding member can be controlled depending on an application of a sliding member by selecting an optimum inorganic powder or inorganic fiber. Particularly, when boron compound powder is selected as the inorganic powder, the friction coefficient (.mu.) of the sliding member can be suppressed to 0.15 or less, and the load at seizure thereof can be improved to 100 kgf/cm.sup.2 or more.
