CARBON-FIBER-REINFORCED SiC-BASED COMPOSITE MATERIAL AND SLIDE MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a carbon-fiber-reinforced SiC composite material of high tensile strength.;SOLUTION: In the carbon fiber-reinforced SiC-based composite material obtained by impregnating a carbon fiber-reinforced composite material with molten metal Si, a carbon fiber for use in the carbon-fiber-reinforced carbon composite material consists of pitch-based carbon staple fibers and the fibers of the pitch-based carbon staple fibers are oriented in two-dimensionally random form. The carbon-fiber-reinforced carbon composite material has 1. 2 to 1.7 g/cm³ bulk density, 15 to 40 vol% porosity and 20 to 50 vol% carbon fiber content on volume basis.;COPYRIGHT: (C)2007,JPO&INPIT
