| 摘 要： | 利用等离子体火炬为高温热源，研究了混杂C／C复合材料的烧蚀性能。结果表明：随着烧蚀区域从火焰中心到边缘的变化，材料的烧蚀特性从中心区域的以热力学烧蚀为主向靠近边缘区域的以热化学烧蚀为主过渡；碳基体和碳纤维的抗热力学烧蚀性能相当，而碳纤维的抗热化学烧蚀特性则明显优于碳基体。

| Abstract: | The ablation property of hybrid C/C composite at high temperature was investigated by the plasma torch as the thermal source. The results show that ablation characteristic of the sample are changed from the center flame region predominantly influenced by thermomechanical ablation to the region close to outer flame influenced mainly by thermochemical ablation. The thermomechanical ablation resistance of carbon matrix is equivalent with that of carbon fibers; but the resistance of thermochemical ablation of carbon fibers is significantly enhanced compared to that of carbon matrix. |
