摘要：

To enhance the oxidation resistance capability of the carbon-bonded carbon fiber composites (CBCFs), a silicide ultra-thick coating as high as 1.6 mm with gradient structure is designed and fabricated via a multi-step rapid sintering method. Compared with other ceramic layers on carbon fiber-based composites, ultra-thick anti-oxidation layer coated-CBCFs have the lowest thermal conductivity. Additionally, ablation behaviors of the ultra-thick ceramics layer coated-CBCFs under the oxyacetylene torch are also investigated. After being exposed to oxyacetylene torch, the ultra-thick ceramics layer coated-CBCFs possess a linear rate range from 0.6 to 1.2 mu m/s, while a mass ablation rate ranges from 4.95 x 10(-5) g/m(2) s to 1.45 x 10(-3) g/m(2) s.
