DEVELOPMENT OF SHORT CARBON FIBER-COPPER COMPOSITE
短碳纤维-铜复合材料的研制

Short cabon fiber-copper composite were made by means of powder me-tallurgy.The fibers in composite were homgeneously distributed in the matrix and orientedrandomly.The tensile strength of the composite increases as the volume of fiber from 0 to2%,but decreases as the volume of fiber increases further.The thermal expansioncoefficient,thermal conductivity and electrical conductivity of the composite become smal-ler as the volume of fiber increases.While heating or cooling to reach certain temperature,the value of thermal expansion coefficiet,thermal conductivity and electrical conductivityremained almost the same.Interface bond exists between short carbon fiber and copper ma-trix.
