Abstract: A new process of preparation of C/ SiC-Cu composite by copper dichloride saturated solution infilt rationand reduction was investigated. The conditions of reduction were studied primarily. The phase identification and microst ructure of the C/ SiC-Cu composite were analyzed by XRD , EDS and SEM. Mechanical properties were evaluated by the three-point flexural test . The results show that the main influencing factors of mass gain are porosityand repeat times. It has been observed that the particle-like or block-like Cu infiltrates into the pores among f iber bundles , also among the filaments. The infiltration of Cu hardly has any effect on the flexural strength of C/ SiC-Cu composite.
