CARBON FIBER COMPOSITE MATERIAL, AND BRAKE MEMBER, STRUCTURAL MEMBER FOR SEMICONDUCTOR, HEAT RESISTANT PANEL AND HEAT SINK USING THE CARBON FIBER COMPOSITE MATERIAL

摘要

There are provided a carbon fiber composite material having higher strength than conventional carbon fiber composite materials, and a brake member, a structural member for semiconductor, a heat resistant panel and a heat sink, all of which use this carbon fiber composite material.;The carbon fiber composite material is obtained by mixing carbon fiber with a resin, subsequently molding the mixture and carbonizing the molded product, and subjecting the resultant carbonized product to melt impregnation with silicon, in which the lattice spacing d002 of the carbon (002) plane of the carbon fiber as measured by an X-ray diffraction method is 3.36 to 3.43. A brake member, a structural member for semiconductor, a heat resistant panel and a heat sink, all of which use this carbon fiber composite material, are provided. The carbon fiber is preferably a carbon fiber obtained by calcining a pitch-derived precursor.
