石墨/环氧、凯芙拉/环氧等先进结构复合材料,由于它们优良的尺寸稳定性、良好的比强度和比刚度等特性,正广泛用于长期飞行的轨道飞行器结构上。然而大部分空间系统的材料在低地球轨道(LEO)和同步地球轨道(GEO)上均将遭受到高真空、热循环、紫外线照射和带电粒子的辐射,材料的性能和寿命都会遭受一定损伤。本文评述了模拟空间环境对结构复合材料性能的影响,提供设计参考。 Graphite / Epoxy, Kevlar / epoxy and other advanced structural composites, are widely used in long-flight orbit aircraft structures due to their excellent dimensional stability, good specific strength and specific stiffness. However, most space system materials are subject to high vacuum, thermal cycling, UV radiation and charged particle radiation on both Low Earth Orbit (LEO) and Synchronous Earth Orbit (GEO) materials, resulting in some damage to material properties and life expectancy. This article reviews the impact of simulated space environment on the properties of structural composites and provides design references.
