STUDY ON FRICTION AND WEAR PROPERTIES OF CARBON FIBER FELT-COPPER COMPOSITES

The friction and wear properties of carbonfiber felt-copper composites fabricated by electrodeposition were studied. Results showed that under the condition of dry friction, the wear resistance of the composites was chiefly related to the existing time of a continuous and effective carbon film formed on both surfaces of the mating pair, which was determ ined by the carbonfiber volume of the composites. The wear resistance of the composites depended on the hardness of the composites and the extra energy necessary to bend and break the fibers under lubricated condition. In both cases, the wear resistance of the composites was much better than that of ZQSn6-6-3.
