二维平纹编织C/SiC复合材料在航天器热防护结构中有着广泛的应用，航天器在高温服役环境中不可避免地会受到外部冲击载荷的作用。本文利用自行设计的同时加热冷却系统对C/SiC复合材料进行了冲击实验研究。比较了C/SiC复合材料在高温和室温下的力学响应和损伤特征。结果表明，冲击损伤模式相似，损伤面积随冲击能量的变化呈现“三阶段”变化趋势，即急剧阶段、线性阶段和稳定阶段。在高温下，3 mm C/SiC板的临界穿透能高于室温下的临界穿透能，冲击能低于13 J时的破坏程度较轻，说明C/SiC板在高温下具有较高的抗冲击性能。但是，当冲击能量超过13 J时，高温下会产生严重的破坏，在这种情况下，热防护结构的设计应引起更多的关注。
2D plain-woven C/SiC has wide application in the Thermal Protective Structures of spacecraft, which will inevitably suffer the external impact load in a high temperature service environment. This paper focuses on the impact experimental study of C/SiC composites by using a specially-designed Simultaneous Heating–Cooling System. The mechanical responses and the damage features of C/SiC composites at high temperature are compared with those at room temperature. Similar damage modes and the “three stages” trend of the damage area vs. impact energy can be found, including the sharp stage, the linear stage and the stable stage. At high temperature, the critical penetration energy of 3-mm C/SiC plate is higher than that at room temperature, and the damage degree is lighter when the impact energy is lower than 13 J, which means the high impact resistance of C/SiC at high temperature under low-energy impact. However, when the impact energy exceeds 13 J, serious damage is found at high temperature; in this case, more attention should be paid to the design of the Thermal Protective Structure.
