Internal antioxidant carbon-carbon composite material
The invention provides an internal antioxidant carbon-carbon composite material. The material comprises a carbon matrix, a carbon fiber reinforcement distributed in the carbon matrix, carbon-coated silicon-rich silicon carbide distributed in pores in the carbon matrix, carbon-coated zirconium oxide distributed in the pores in the carbon matrix, zirconium phosphate distributed in the pores in the carbon matrix and aluminum oxide distributed in the pores in the carbon matrix. The invention also provides a preparation method of the internal antioxidant carbon-carbon composite material. According to the antioxidant carbon-carbon composite material, zirconium phosphate and zirconium chloride are introduced into the carbon-carbon composite material through impregnation, the ablation resistance of the composite material can be greatly improved, and the introduction of silicon-rich silicon carbide can supplement defects through internal permeation of the material when the internal material has defects, so that the service life of the composite material is further prolonged.
本发明提供一种内部抗氧化碳碳复合材料，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碳包覆的富硅的碳化硅、分布于碳基体内部空隙中的碳包覆的氧化锆、分布于碳基体内部空隙中的磷酸锆和分布于碳基体内部空隙中的氧化铝。本发明还提供了一种内部抗氧化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磷酸锆、氯化锆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。
