Fiber-reinforced heat-resistant sound-absorbing material and process for producing the same |
摘要 |
A production process which comprises a preform formation step of forming a fiber preform made of silicon carbide short fibers having heat resistance of 1000° C. or greater; a sol-gel preparation step of preparing a sol-gel solution containing a heat resistant compound having heat resistance of 1000° C. or greater; an impregnation-drying-calcination step of impregnating the fiber preform with the sol-gel solution, followed by drying and calcining; and a crystallization step of crystallizing the fiber preform after impregnation, drying and calcination.
