Abstract Using carbon non-woven fabric/fibre web as the reinforcements, porous C/C composites were prepared by chemical vapor infiltration (CVI) deposition of pyrolytic carbon, and then SiC was deposited by CVI and Cu was infiltrated under pressure successively. Fianlly, C/C-SiC-Cu composites were obained. The effects of density of porous C/C composites and SiC contents (volume fraction φ, the same below) on the flexural property of C/C-SiC-Cu composites were investigated, respectively. The results show that with the increase of porous C/C composites density and SiC content, pyrolytic carbon and SiC form an interface with high binding strength around carbon fibers, and the strengthening effect of them can be fully played. So the flexural strength of C/C-SiC-Cu composites significantly increase. When the bending process is carried out, pyrolytic carbon and SiC matrix can inhibit the pullout of carbon fibers. The flexural load-displacement curve of C/C-SiC-Cu composites is ups and downs step-like, showing obvious characteristics of pseudoplastic fracture.

Key words： C/C-SiC-Cu composites porous C/C composite SiC microstructure flexural strength
