柔性热控材料作为航天器表面材料,在轨服役过程中要经受带电粒子辐照、高真空、原子氧、交变温度场等各种空间环境因素的作用,柔性热控材料的性能及其空间稳定性对维持航天器正常工作环境至关重要.对柔性热控材料的工作原理及主要应用作简单介绍,重点综述柔性热控材料性能空间稳定性的研究现状,具体分析空间辐照、原子氧、充放电及空间微粒子对材料性能的影响,并阐述相应的防护措施.
As a spacecraft surface material, flexible thermal control material will endure the various effects of space environment during service, including those of charged particle radiation, high vacuum, atomic oxygen, alternate fields of temperature. Its performance and space stability are vital to sustain the spacecrafts in the normal condition. In this paper, the working theory and key applications are briefly introduced and the emphasis is placed on the research status of performance stability of flexible thermal control materials. The influences of space irradiation, atomic oxygen, space charge-discharge and space particle on performance of materials are analyzed in detail and corresponding protective measures are presented.
