    摘要:

    综述了国内外空间探测器烧蚀防热材料的种类及其应用情况,美国主要包括高密度酚醛/玻璃钢、蜂窝增强烧蚀防热材料、PICA及PICA-X以及高密度碳酚醛材料等,国内则主要包括酚醛/尼龙、蜂窝增强烧蚀防热材料和NF材料,介绍了这些材料所应用的探测器、气动加热环境、防热材料性能和防热结构成型技术。总结了美国空间探测防热材料研制中出现的两次烧蚀异常及导致的探测器选材变化,可见防热材料与热环境耦合关系复杂。同时介绍了我国针对防热材料抵御异常损伤开展的部分工作。最后对空间探测防热材料的应用与发展做出了展望。

    Abstract:

    The categories and applications of ablation thermal protection materials for space exploration have been reviewed, including high density glass fiber reinforced phenolic plastics, honeycomb reinforced ablation thermal protection materials, PICA and PICA-X, high density carbon phenolic of US, and nylon phenolic, honeycomb reinforced ablation thermal protection materials and NF material of China. The applied space exploration probe, aerodynamic heating environment, the properties and manufacture technology of the thermal protection structure are introduced. The anomaly ablation cases of the materials and the selected materials change of US space exploration are summarized. It can be seen that the coupling relationship between thermal protection material and heat environment is complex. The research of thermal protection material on resisting anomaly damage in our country is presented. The application and development of the thermal protection materials for space exploration are prospected in the end.
