以Si 0. 87 Zr 0. 13合金为原料，采用反应熔渗法制备了C/C-SiC-ZrC复合材料。采用化学气相渗透法对碳纤维毡进行碳渗透，得到多孔碳/碳（C/C）骨架。然后将熔融的Si 0. 87 Zr 0. 13合金渗透到多孔C/C中，得到C/C-SiC-ZrC复合材料。C-SiC-ZrC基体呈梯度结构，碳和SiC沉积在纤维束附近。结果表明，C/C-SiC-ZrC复合材料具有较高的强度、良好的抗氧化性和优异的耐烧蚀性。这些性质归因于梯度矩阵结构。
Carbon fiber reinforced carbon–silicon carbide–zirconium carbide (C/C–SiC–ZrC) composites were prepared by reactive melt infiltration (RMI) with Si0.87Zr0.13alloy. Carbon fiber felt was firstly infiltrated by carbon using chemical vapour infiltration to obtain a porous carbon/carbon (C/C) skeleton. The molten Si0.87Zr0.13alloy 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.
