Carbon-carbon composite material containing refractory metal
The invention provides a carbon-carbon composite material containing refractory metal. The carbon-carbon composite material comprises a carbon matrix, a carbon fiber reinforcement distributed in the carbon matrix, metal zirconium-fullerene composite nano powder distributed in internal pores of the carbon matrix and silicon-rich silicon carbide distributed in the internal pores of the carbon matrix. The invention further provides a preparation method of the carbon-carbon composite material containing the refractory metal. According to the anti-oxidation carbon-carbon composite material provided by the invention, the metal zirconium-fullerene composite nano powder is introduced into the carbon-carbon composite material through impregnation, so that the ablation resistance of the composite material can be greatly improved, the introduction of silicon-rich silicon carbide can supplement defects through internal permeation of the material when the internal material has defects, and the service life of the composite material is further prolonged. Fullerene is used for coating metal zirconium, and due to the fact that metal zirconium is introduced, defects appear in the material, and improvement of the oxidation resistance is facilitated.
本发明提供一种含难熔金属的碳碳复合材料，包括碳基体、分布于碳基体内的碳纤维增强体、分布于碳基体内部孔隙中的金属锆‑富勒烯复合纳米粉体、分布于碳基体内部空隙中的富硅的碳化硅。本发明还提供了一种含难熔金属的碳碳复合材料的制备方法。本发明提供的抗氧化碳碳复合材料通过浸渍将金属锆‑富勒烯复合纳米粉体引入碳碳复合材料内部，可大大提高复合材料的耐烧蚀性能，而富硅的碳化硅的引入可在内部材料出现缺陷时通过材料内部渗透补充缺陷，进一步提高了复合材料的使用寿命；利用富勒烯将金属锆包覆因为引入金属锆导致材料内部出现的缺陷，有利于抗氧化性能的提高。
