Summary

Flexural strengths and critical intensive factors for silicon carbide short fibers in silica gel matrix were determined after the composites have been heat treated. Although the composites were still porous after a heat treatment at 1400°C for 4 h in argon atmosphere, σflex and KIC are compared favorably with other ceramic composites that were fabricated mostly by the conventional hot-pressing technique. The σflex and KIC values further improved after the values were divided by the density values.
