In the present study, fiber-reinforced self-healing ceramic, which has SiC interlayer acting as self-healing agent at alumina matrix/ alumina fiber interface, was developed. It is found that the developed composite can completely recover strength by the heat treatment for 1h at 1200 ℃ and 50 h at 1000 ℃ Furthermore, the composite was found to maintain the good ability of fiber reinforcement after self-healing treatment. From the obtained results, the composite can heal the pre-crack fast compared to particle dispersed self-healing ceramics, in order that it spread the crack to the interlayer consisting of healing agent. The results imply that the developed fiber-reinforced self-healing ceramic can ensure its structural integrity against the accidental damage, such as, crash and thermal shock.
