Cu-C composite is one of the most potential materials for pantograph slide plate, which is an important component of pantograph system in locomotive. The principle of wettability between Cu and C was investigated in this paper. The element of Mo was selected to improve the wettability between Cu and C. The fabrication process of cold compression sintering fiber reinforced Cu-C composite and its effect on the composite property were studied. The wear and friction mechanism of Cu-C composite was investigated initially by electriferous friction test.
