<P>PROBLEM TO BE SOLVED: To provide a fibrous composite having improved strength and toughness and to provide a method of manufacturing the fibrous composite. <P>SOLUTION: The fibrous composite having improved strength and toughness is manufactured by adding a compound containing a metal element to polysilane or heated reaction product thereof and causing a reaction by heating under an inert gas to prepare a metal element-containing organosilicon polymer, preparing a spun fiber from the metal element-containing organosilicon polymer, heating the spun fiber under an oxygen-containing gas to prepare an infusibilized fiber, heating the infusibilized fiber under an inert gas to form a mineralized fiber, mixing a plurality of the mineralized fibers with a plurality of reinforcing fibers or their bundle to make a preliminarily shaped material, charging the preliminarily shaped material into a mold and pressing at a high temperature in a gas such as an inert gas. <P>COPYRIGHT: (C)2007,JPO&INPIT |
