Three composites of C/C-Cu i.e. carbon fiber reinforced carbon-copper mesh with different volume fraction (35%,40% and 45%) of carbon fiber were prepared by pressing mold method and then followed by four times impregnating with resin and three times high temperature carbonizing . Their compressive properties were measured on Instron-3369 mechanical testing machine. The effect of volume fraction of carbon fiber on the compressive property was investigated. The results show that the compression performance of C/C-Cu composites increased with increase of volume fraction of carbon fiber in the vertical direction. The compression strength of the composite with 40% carbon fiber was 20% higher than the one with 35%, and that with 45% carbon fiber was 13% higher than the one with 40%. These imply claerly that the compression strength of the composites first increased and then decreased with the increasing carbon fiber content. On the other hand, the carbon fiber volume fraction has no significant effect on the compression performance in the parallel direction. Among others, the composite with 45% carbon fiber has the best compression strength in both the vertical direction and parallel direction, i.e. 190.13MPa and 83.39MPa respectively. The difference of compressive strength in the vertical direction and parallel direction shows that the compression property of C/C-Cu composites was obviously of anisotropy. By compression stress the composite damaged in the vertical direction along 45°diagonal and in the parallel direction at the interface between the carbon fiber and copper mesh.
