PROBLEM TO BE SOLVED: To obtain long fiber reinforced composite ceramics easily workable in a complex shape at a low cost by forming a skeleton of chemically bonded crossing inorg. long fibers each having a specified radius of curvature on a ceramic matrix. SOLUTION: This composite ceramics has a skeleton of chemically bonded crossing inorg. long fibers each having >=0.5mm radius of curvature in the ceramic matrix. the inorg. long fibers are preferably made of at least one kind of coned. such as silicon carbide, Si-C-O, silicon nitride, Si-N-O, Si-Ti-C-O, aluminum nitride, chromium nitride or zirconium nitride. The ceramic matrix preferably contains nitride, carbide oxide oxynitride or carbonitride of at least one among Si, Al, Cr, Ti, Zr, Hf, W and Y. |
