Fabrication and properties of Carbon/Copper Composites by Hot Pressing

Fabrication technique of discontinous carbon fiber reinforced copper-5%tin matrix materials was studied.The Carbon fiber was well composited with the copper and tin powder without pressing. The dense composites with the carbon fiber volume content ranging from 10% to 50% were made in the given technology.The fiber homogeneously distributed in the matrix and has a random orientation.The properties of the composites such as hardness, electric resistance, coefficient bending strength, tribological behavior were tested and the effect of the fiber content on the properties of the materials were also disscaussed.Furthermore, the bending fracture and wearing surface were observed by the use of scanning electron microscope.
