摘要

Carbon fiber reinforced carbon-silicon carbide-zirconium carbide (C/C-SiC-ZrC) composites were prepared by reactive melt infiltration (RMI) with Si 0.87Zr 0.13 alloy. Carbon fiber felt was firstly infiltrated by carbon using chemical vapour infiltration to obtain a porous carbon/carbon (C/C) skeleton. The molten Si 0.87Zr 0.13 alloy was then infiltrated into the porous C/C to obtain C/C-SiC-ZrC composites. The C-SiC-ZrC matrix showed a gradient structure with deposited carbon and SiC close to the fiber tows. It has been found that the C/C-SiC-ZrC showed a high strength, good oxidation resistance, and excellent ablation resistance. These properties are attributed to the gradient matrix structure.
