EFFECTS OF MANUFACTURING PROCESS ON PROPERTIES OF COPPER-LEAD-CARBON FIBER COMPOSITE BEARING MATERIALS

Several different processes of cold pressing and sintering, repressing and resintering, Secondary repressing and resintering and hot pressing were respectively adopted for manufacturing short carbon fiber reinforced copper-lead alloy (copper-lead-carbon fiber) composite haring materials. The results show that the influence of manufacturing process on the properties of carbon fiber cormposite materials is more obvious than on that of traditional P/M materials. The presence of carbon fiber has set a special technological requirement for the manufacture of composite materials. The traditional P/M process can not be wilful to manufacture fiber composite materials.
