Abstract

Advanced fiber reinforced ceramic composite (FRC) having self-healing function has been developed. The composite includes the silicon carbide interlayer as healing agent at the interface between alumina fiber and alumina matrix. The healing agent interlayer caused the preferential fracture of the fiber/matrix interface and the interface fracture gave rise to the slip of the interface during crack propagation. Thereby the FRC could exhibit a large deformation at the fracture and large fracture energy. Moreover, the high temperature oxidation of the healing agent made the interface delimitation rebounded by the formed oxide and the reaction heat. As a result, the maximum strength and the stiffness degraded by the interface delimitation could be recovered by the healing. Consequently, it was found that the FRC containing the interlayer of the healing agent can survive the repeated crack propagation or initiation due to the large impact damage.
