New material concept of continuous SiC fiber-reinforced porous SiC matrix (SiC/porous SiC) composites has been invented for the development of ultra-high temperature materials with high oxidation/corrosion resistance and excellent high-temperature strength over 1000 C. In this study, innovative SiC-based composites without any interface between fiber and matrix like carbon have been successfully developed. The composites showed pseudo-ductile behavior and complicated fracture behavior due to enhanced debonding at fiber/matrix interface and frictional stress at the debonded fiber/matrix interface. The porous SiC composites were exposed at elevated temperature up to 1100 C in air. No apparent degradation of flexural strength was observed compared to that of the as-received material. Another fabrication route have been proposed from the view point of the reduced production cost and demonstrated.

为了开发具有高抗氧化/耐腐蚀性能和1000℃以上高温强度的超高温材料，发明了连续SiC纤维增强多孔SiC基（SiC/多孔SiC）复合材料的新材料概念。本研究成功开发了碳等无纤维与基体界面的创新型SiC基复合材料。由于纤维/基体界面的脱粘和摩擦应力增强，复合材料表现出伪延性和复杂的断裂行为。将多孔碳化硅复合材料暴露在空气中高达1100℃的高温下。与接收材料相比，未观察到明显的弯曲强度退化。从降低生产成本的角度提出了另一种制造路线，并进行了论证。
