航天器材料空间环境适应性评价技术

航天器及其使用的材料在轨服役期间要经受真空、热循环、辐照、原子氧及碎片等空间环境的作用,航天器材料的空间环境适应性是其区别于其它材料的一项重要质量特性,评价其适应性是航天器材料质量保证工作的重要内容。推进评价技术的发展,实现航天器材料质量,可以保证各个环节中对材料空间环境适应性的有效分析、评估与控制,是促进航天器可靠性提升所面临的一项重大问题。针对原材料选用、认定、复验等环节中的应用需求,分析了空间环境适应性评价技术目前存在的差距,并对今后的发展进行了展望。

Summarization Space Environmental Worthiness Evaluation Technology for Spacecraft Material

Spacecraft and its material during in-orbit service needed to endure the action of space environmental factors, such as vacuum, thermal circulation, radiation, atomic oxygen, and debris. Space environmental worthiness of spacecraft material is an important quality characteristics and its worthiness evaluation is the important content of spacecraft material quality assurance. Driving the development of evaluation technology, and realizing effective analysis, evaluation and control of material space environmental worthiness in every links of space material quality assurance are important issues to improve spacecraft reliability. According to the application requirements of the links of material selection, cognizance, and verification, the existing problems of space environmental worthiness evaluation technology was analyzed, and future development was prospected.
