BN COATED SiC FIBER AND MANUFACTURING METHOD THEREFOR, SiC FIBER REINFORCED SiC COMPOSITE MATERIAL USING BN COATED SiC FIBER
To provide a BN coated SiC fiber by adsorbing BN particles to a SiC fiber surface, and a SiC fiber reinforced SiC composite material having high breaking energy.SOLUTION: There is provided a SiC fiber reinforced SiC composite material by laminating a plurality of sheets woven with a BN coated SiC fiber consisting of a SiC fiber 1 and BN particles 2 coating a surface of the SiC fiber 1, in which particle diameter of the BN particles 2 is 1/20 to 1/100 of fiber diameter of the SiC fiber 1. There is provided a manufacturing method of the BN coated SiC fiber having: a process 1 for adsorbing the BN particles 2 charging an electric charge opposite to the SiC fiber 1 on a surface of the SiC fiber 1 charging positive or negative; a process 2 for adsorbing the BN particles 2 charging the electric charge opposite to the BN particles 2 of the process 1 on the surface of the SiC fiber 1 to which the BN particles 2 are adsorbed to obtain the BN adhered SiC fiber 1 to which the BN particles 2 charging positive and negative are adhered alternatively; and a process 3 for heating the BN particles 2 adhered SiC fiber 1.SELECTED DRAWING: Figure 3
【課題】ＢＮ粒子をＳｉＣ繊維表面に吸着させたＢＮ被覆ＳｉＣ繊維及び、高い破壊エネルギーを有するＳｉＣ繊維強化ＳｉＣ複合材の提供。【解決手段】ＳｉＣ繊維１と、ＳｉＣ繊維１の表面を被覆するＢＮ粒子２とからなり、ＢＮ粒子２の粒径が、ＳｉＣ繊維１の繊維径の１／２０以下、１／１００以下であるＢＮ被覆ＳｉＣ繊維を製織したシートを複数枚積層させてなるＳｉＣ繊維強化ＳｉＣ複合材。正又は負に帯電したＳｉＣ繊維１の表面にＳｉＣ繊維１とは反対の電荷に帯電したＢＮ粒子２を吸着させる工程１と、ＢＮ粒子２が吸着したＳｉＣ繊維１の表面に工程１のＢＮ粒子２とは反対の電荷に帯電したＢＮ粒子２を吸着させ、その後、正及び負に帯電したＢＮ粒子２を交互に吸着させたＢＮ付着ＳｉＣ繊維１を得る工程２、と、得れたＢＮ粒子２付着ＳｉＣ繊維１を、加熱する工程３とを有するＢＮ被覆ＳｉＣ繊維の製造方法。【選択図】図３
