  • Patent number: 6245283
    Abstract: A fiber-bond type ceramic material 4 is produced by using as raw material fibers 1 inorganic fibers of Si—M—C—O synthesized by melt spinning polycarbosilane, then infusibilizing the produced threads, and firing the set threads, forming from the raw material fibers a woven fabric 2 having all the fibers thereof extended perpendicularly or obliquely relative to the direction of compression during the course of a hot-press fabrication at a weaving step 12, heat-treating the woven fabric in the air, thereby preparing a woven fabric of oxidized fibers 3 provided with an oxide layer on the surface thereof at an oxidizing step 14, and subjecting the woven fabric of oxidized fibers to a hot-press fabrication while compressing the fabric in the direction of the compression thereby causing the oxide layers on the surface to adhere fast to each other and form a matrix at a hot-press step 16.
