The effect of fiber arrangements and additional elements on reciprocating sliding wear characteristics of copper-carbon fiber composite was studied. Results obtained in this study were as follows:
(1) The wear volume of the copper-carbon fiber composite appeared to be smaller than that of copper alloys.
(2) The wear volume of the copper-carbon fiber composite became larger, as the sliding load increased and the volume fraction of carbon fiber increased beyond 30 volume percent.
(3) The effectiveness of fiber arrangement in reducing the wear volume was the highest in the random arrangement, medium in the direction perpendicular to the unidirectional fiber direction and the lowest in this fiber direction.
(4) The wear volume of the composite was decreased by the addition of Sn and Zr. However, the addition of these elements could not achieve the isotropic wear characteristics of the composite.
(5) It was found that the isotropic wear characteristics of the composite could be obtained by the addition of carbon powder. The isotropic wear characteristics and the reducing wear volume of the composite could be attained by the addition of Zr and carbon powder together.
