<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a hollow body made from a fiber-reinforced composite which is converted to a fiber-reinforced carbide ceramics by being infiltrated with and reacted with a liquid metal. <P>SOLUTION: A mixture of carbon fiber and/or carbon filament with a thermosetting binder capable of being carbonized is charged into a metal die core for molding a hollow body shape and heated at 120-280°C under pressure to form a green body. Next, the green body is heated at about 750-2,400°C under a non-oxidizing atmosphere to be carbonized and/or graphitized to manufacture a C/C body. The heating for hardening, carbonizing and/or graphitizing is carried out by at least partially passing electric current through the composition mixture, the green body or the metal die core. <P>COPYRIGHT: (C)2003,JPO |
