The fiber strength and the interface shear strength between fiber and matrix have been measured by AE technique. It is found that the interface shear strength and the fiber fracture strength as well as the interface properties are sensitive to the surface treatments of fiber. The SiC_w / Al composite made of SiC treated by SiO_2 possesses the better interface properties, whereas, the composite made of SiC treated by C has the brittle interface.
