摘　　要：在原子氧剥蚀效应地面模拟设备中对一种抗原子氧复合材料β布进行了原子氧剥蚀效应试验、试样温度升高对原子氧效应的影响试验以及原子氧与紫外辐射复合效应试验研究 ,对试验前后 β布试样的质量及表面形貌进行了比较 ,得出了材料在设备中的反应特点以及温度变化、紫外辐射对材料的原子氧效应的影响规律。另外对这种材料与原子氧的反应机理进行了分析 。Beta cloth is an AO resistant spacecraft composite material,on which experiments are conducted in this paper to investigate the atomic oxygen effects,the impact of the temperature change on the atomic oxygen effects and the ultraviolet radiation effects with atomic oxygen effects ground based simulation facility.The sample material before and after the experiments is compared in mass and surface morphology.The reaction characteristics of the material in the facility and the impact of temperature change and ultraviolet radiation on atomic oxygen effects were acquired.Through analyzing the reaction mechanism between atomic oxygen and beta cloth,it was concluded that the collision of energetic particle will be an important factor.
