| Abstract: | ABSTRACTThe copper-matrix composite contains carbon-fibre powder which is prepared using a powder metallurgy sintering process in an effort to examine the effects of 50-mesh (270?μm) carbon-fibre powder on the microstructure and, friction and wear properties of copper matrix composites at high speed. When carbon-fibre powder is added within a certain range, the friction coefficient of the composite material is increased and the amount of wear is greatly reduced, When the content of carbon-fibre powder is 0.2wt-%, the hardness, density, friction and wear properties of the copper-based composite material has the best combination. |
