Abstract
A fiber-bond type ceramic material,is produced by using as raw material fibers,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,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,, heat-treating the woven fabric in the air, thereby preparing a woven fabric of oxidized fibers,provided with an oxide layer on the surface thereof at an oxidizing step,, 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
