PURPOSE:To constitute the title material so that fracture is rare, deterioration in dimensional accuracy can be corrected and the same is superior in elasticity, adhesion, shape retention and heat insulation properties, by a method wherein a molded layer obtained by joining carbon fibers to each other by carburized or graphitized thermosetting resin or pitch and a carbon fiber felt layer are laminated. CONSTITUTION:A molded layer 1 is formed by a method wherein a fiber or a carbon fiber felt which can be made into carbon fiber is impregnated with graphitizable thermosetting resin, compression-molded and graphitized. A carbon fiber felt layer 2 is obtained by a method wherein felt is manufactured by performing mixed spinning, for example, of a phenolic resin fiber contracting by firing with the carbon fiber, the phenolic resin fiber is contracted at the time of the firing and carburized or graphitized. A carbonaceous binder layer 3 laminating and integrating the molded layer 1 and carbon fiber felt layer 2 is formed by a method wherein carburizable or graphitizable pitch or the thermosetting resin is applied to the surface of the carbon fiber felt layer 2 and the surface of the minute molded layer 1 and carburization and graphitization are performed. |
