【摘要】：隔热材料是飞行器热防护关键材料之一。尤其针对受长时间气动加热的超高速飞行器,机体表面产生高温,既要求隔热材料能有效阻隔热量进入机体内部影响电子电气设备正常工作并兼具优异的热稳定性,又要求其质轻,耐候性优良以应对多次重复使用和降低隔热材料本身所带来的能耗。文中综述了以酚醛泡沫复合隔热材料、氧化铝泡沫陶瓷材料及新型纳米隔热材料为代表的航空航天用隔热材料技术最新研究进展,详细介绍了这些隔热材料的组成、结构和性能特点,在此基础上展望航空航天用新型隔热材料的未来发展。
[Abstract]:Thermal insulation material is one of the key materials for thermal protection of aircraft, especially for ultra-high speed aircraft heated for a long time, which produces high temperature on the airframe surface. It is required that the thermal insulation material can effectively block the heat into the body to affect the normal operation of electronic and electrical equipment and has excellent thermal stability, but also requires its light weight. The weather resistance is good to deal with repeated use and to reduce the energy consumption caused by the insulation material itself. The phenolic foam composite insulation material is reviewed in this paper. The latest research progress of alumina foam ceramic materials and new nano-insulating materials for aerospace thermal insulation technology is introduced in this paper. The composition, structure and properties of these insulating materials are introduced in detail. On this basis, the future development of new thermal insulation materials for aerospace applications is prospected.
