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.
