摘要: 采用浆料浸渍法引入ZrB2微粉作为耐超高温相, 以炭纤维为增强体, 以热解炭和SiC为基体, 制备了ZrB2含量不同的耐超高温C/C-SiC-ZrB2复合材料; 通过电弧风洞考核材料的抗烧蚀性能, 通过XRD、SEM和EDS分析材料的烧蚀机理。结果表明: 在Ma 6电弧风洞条件下, C/C-SiC-ZrB2复合材料的抗烧蚀性能优于C/C-SiC, 且随着ZrB2含量的增加, 抗烧蚀性能随之提高; 在高温阶段形成的ZrO2-SiO2玻璃态熔融层起到了抗氧化烧蚀的作用。

Abstract: The ultra-high-temperature composites C/C-SiC-ZrB2 were prepared by slurry impregnation method. The composites consist of the carbon fiber as the reinforced phase, C and SiC as the matrix, and the micro-particle ZrB2 as the ultra high temperature phase. The ablation resistance properties of the composites were assessed by arc wind tunnel testing. The ablation mechanism was studied through XRD, SEM and EDS measurements. The results indicate that compared with C/C-SiC composites, the C/C-SiC-ZrB2 composites show better ablation resistance properties, and the properties increases with the content of ZrB2 increase. A ZrO2-SiO2 glassy melting layer formed at high temperature plays an important role in antioxidant ablation.

Key words: ultra-high-temperature composites, C/C-SiC-ZrB2 increase, ablation resistance properties, ablation mechanism
