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.

The preform is formed from a precursor having a predetermined extension. The outer circumferential portion corresponds to a first region where a first plurality of reinforced fibers is partially disposed in parallel along the curved line for bending. The inner circumferential portion corresponds to a second region constituted solely of a second plurality of reinforced fibers disposed throughout the entire area, so as to intersect the first plurality of reinforced fibers at a predetermined angle in the first region.

Abstract: A unidirectional three dimensional fiber structure is provided which does not require weaving, displays a high level of interlayer strength and does not suffer from cracking, and which can also be easily produced with any arbitrary cross-section. A unidirectional three dimensional fiber structure is produced by inserting a plurality of long fibers which have been aligned unidirectionally into an inlet at one end of a cylindrical die with a plurality of needle holes in the peripheral walls thereof, and then performing needlepunch through the needle holes while drawing the plurality of long fibers out from an outlet at the opposite end of the cylindrical die.
