【Abstract】 The possibility of producing short carbon fiber reinforced copper matrix composite has been studied in the paper. The composite has highdensity and carbon fibers are well-distribtited in the matrix The effect ofvolume of carbon fiber on the tensile strength, thermal expansion coeffici-ent thermal conductivity and electrical conductivity of the composite hasbeen studied.The results indicate that the tensile strength, thermal expallsion coefficient,thermal conductivity and electrical conductivity dec-rease with the increase of the volume of carbon fiber.更多还原
