【Abstract】 The interface of alumina short fiber reinforced alluminum alloy composite is studeied on the basis of the composites manufactured by the squeeze infiltration method. The results of the study indicate that there are obvious interface layers between the fibers and the matrix in the composites, and the alloy elements may improve wetting state through the suritable chemical reaction to be favorable to combination between the fibers and the matrix. The analysis of the specimen fracture also indicates that the interface between the fibers and the matrix is strong enough to transmit loads to the fibers so as to play the reinforcing role of the fibers.更多还原
