摘要
刚性陶瓷纤维隔热瓦基体辐射式热防护涂层是航天飞行器大面积使用的热防护系统,提高其辐射率、抗冲击、抗热震等可重复使用性能一直是研究重点。本文综述了多元化性能优化背景下刚性陶瓷纤维隔热瓦基体辐射式热防护涂层结构设计和材料改进的研究进展,分析了辐射式热防护涂层的结构设计途径和组成调整思路,涂层从单层致密结构发展到多层梯度结构以及多层鳞片结构,并总结了不同结构辐射式热防护涂层的优势和存在问题。最后指出多层梯度结构涂层由于综合了致密结构和多孔梯度结构的综合优势且具有可调节性仍是当前研究的主流,未来辐射式热防护涂层应进一步优化防/隔热一体化设计,并开展结构、组成对服役仿真环境下的性能影响研究。
Radiation thermal protection coating based on rigid ceramic fiber insulation tile is a thermal protection system widely used in spacecraft,and improving its reusable performance such as emissivity,impact resistance,and thermal shock resistance has always been a research focus.This article reviews the research progress on the structural design and material improvement of radiation thermal protective coatings for rigid ceramic fiber insulation tiles under the background of diversified performance optimization.The structural design approach and composition adjustment ideas of radiation thermal protective coatings are analyzed,from single-layer dense structure to multi-layer gradient structure and scaly structure,and the advantages and existing problems of radiant thermal protection coatings with different structures are summarized.Finally,it is pointed out that multilayer gradient structure coatings,due to their comprehensive advantages of dense top layer and porous gradient structures and their adjustability,are still the mainstream of current research.In the future,radiant thermal protection coatings should further optimize the integrated design of thermal insulation,and conduct research on the impact of structure and composition on performance in service simulation environments.
