摘要：
The experimental study was performed on tensile strength of high volume fraction SiCp/Al composites. The results show that the loading and unloading processes have little effect on the tensile strength of high volume fraction SiCp/Al composites. An FEM model was established to simulate the tensile properties of SiCp/Al composites. The simulated results show that low volume fraction SiCp/Al composites mainly represent plastic mechanical properties. On the contrary, high volume fraction SiCp/Al composites mainly represent the brittle mechanical properties. The errors of the tensile strength got from the model are little compared with the testing results. Breakage of matrix is the main factor of high volume fraction SiCp/Al composites tensile failure.
