CARBON-FIBER-REINFORCED SiC COMPOSITE MATERIAL AND SLIDE MEMBER

摘要

A carbdn-fiber-reinforced SiC composite having a high tensile strength is produced by impregnating a carbon-fiber-reinforced carbon composite with melted metal Si. The carbon-fiber-reinforced carbon composite includes carbon fibers that are pitch-based short carbon fibers. The pitch-based short carbon fibers are oriented in two-dimensional random directions. The carbon-fiber-reinforced carbon composite has a bulk density of 1.2 to 1.7 g/cm3, a porosity of 15 to 40 vol%, and a carbon fiber volume content of 20 to 50 vol%.
