STUDY OF PROPERTIES OF CARBON FIBER REINFORCED COPPER MATRIX COMPOSITES

The short carbon fiber reinforced copper matrix composites were prepared by power metallurgy. The effect of the volume content of carbon fiber on hardness and electrical conductivity of the CF-Cu composite was studied. The friction and wear properties of CF-Cu composite under dry friction condition were studied and the involved wear mechanism was analyzed by observing the wear surface of composites. For the CF-Cu composites with different carbon fiber content, with the increasing of carbon fiber content, hardness and wear resistant ability of the CF-Cu composite increase, but the electrical conductivity decreases.
