- 摘要:
- 以PZC为有机锆先驱体原材料，采用A，B，C三种PIP工艺路线制备了不同ZrC含量的C/SiC-ZrC复合材料，并对C/SiC-ZrC复合材料的组成、微观结构、力学性能、烧蚀性能及作用机理进行了测试和分析。结果表明，有机锆先驱体制备的C/SiC-ZrC复合材料烧蚀性能有大幅提高，但其力学性能却存在一定程度的下降，并且随着ZrC含量的增加，C/SiC复合材料的力学性能呈现出逐渐降低的趋势，其质量烧蚀率和线烧蚀率呈现出先减小后增大的趋势。
- Abstract:
- Taking PZC as the raw material of organic zirconium precursor, C/SiC-ZrC composites with different ZrC content were prepared by three PIP processes. The composition, microstructure, mechanical properties, ablative properties and mechanisms of the C/SiC-ZrC composites were tested and analyzed. The results showed that the ablative properties of C/SiC-ZrC composites prepared with the organic zirconium precursor have been improved greatly, but its mechanical performance has a certain degree of decline, and with the increase of ZrC content, the mechanical properties of C/SiC composites decreased gradually, but its mass ablation rate and linear ablation rate appear as decreasing trend at first and then increasing trend.
