BN COATED SiC FIBER AND MANUFACTURING METHOD THEREFOR, SiC FIBER REINFORCED SiC COMPOSITE MATERIAL USING BN COATED SiC FIBER

摘要

PROBLEM TO BE SOLVED: To provide a SiC fiber reinforced SiC composite material high in breaking energy, and a manufacturing method therefor.;SOLUTION: There is provided a SiC fiber reinforced SiC composite material by laminating a plurality of sheets woven with a BN coated SiC fiber bundle consisting of a SiC fiber 1, and first BN particles 2 and second BN particles 2' coating a surface of the SiC fiber 1, in which particle diameter of the first BN particles 2 is 1/10 or less of fiber diameter of the SiC fiber 1, and particle diameter of the second BN particles 2' is 1/10 or less of the particle diameter of the first BN particles 2.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
