<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing tubular SiC fiber-bonding ceramics superior in heat resistance and smoothness, composed of SiC fiber-bonding ceramics having high destruction toughness, maintaining equal structural material characteristics even if the material is thick, in a shape close to a member shape. <P>SOLUTION: The method for manufacturing the tubular SiC fiber-bonding ceramics includes winding silicon carbide-based inorganic fibers in the circumferential direction of a heat resistant core where multiple cylindrical shapes are slit in the longitudinal direction of a cylindrical surface, to form a preliminary formed body where a layer made of silicon carbide-based fibers is formed around the core, and taking out a slit core after the preliminary formed body is hot-pressurized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
