摘要	A novel Cu matrix composite reinforced by MoSi2 intermetallic was developed by hot pressing sintering method. The microstructure, mechanical properties and conductive properties of the Cu matrix composite were investigated. The results indicate that MoSi2 is an effective reinforcement for Cu and the MoSi2/Cu composite exhibit good stability. MoSi2 can effectively restrain growth of grains of Cu matrix during sintering. With the increase of MoSi2 content, density and conductivity of the composite decrease, and its hardness and tensile strength increase first and then decrease. The composite with 2% MoSi2 exhibits the optimal combination of performance with relative density of 97.44% and conductivity of 68% IACS. Hardness and tensile strength of the composite with 2% MoSi2 are 142HV and 355MPa, respectively. Its tensile strength is twice of the pure Cu sintered at the same preparation condition.
