摘要：

C/C-SiC composites were fabricated by infiltrating Si into C/C porous preforms that were prepared by chemical vapor infiltration (CVI). The effect of the SiC content on the friction and wear properties of C/C-SiC composites was investigated. It demonstrates that the friction coefficient of the C/C-SiC composites first goes up and then falls down and reaches its maximum value of 0.62 when the content of the SiC is 29.88%. And the changing regularity of the friction coefficient and linear wear is coincident when the content of the SiC is lower than 33.56%, however is opposite when the content of the SiC is higher than 33.56%. Comprehensively considering, the tribological properties of the C/C-SiC composites is optimum when the content of the SiC is 33.56%.
