Experimental Investigations of Atomic Oxygen Effects on a Carbon Fiber/Epoxy Resin Composite Material
-
摘要: 碳纤维/环氧树脂用在空间飞行器上时,面临着空间环境中各种因素特别是原子氧效应的影响,因而在地面模拟设备中对这种材料进行了原子氧剥蚀效应试验研究,并且考察了温度变化的影响.通过比较试验前后试样的质量及表面形貌,得出了材料在设备中的反应特点以及温度变化对材料原子氧效应的影响规律.同时,还对设备中存在的离子氧在材料的质量损失中所起到的作用进行了定性的研究.Abstract: When used in spacecrafts, carbon fiber/epoxy resin is affected severely by many factors of space environment, especially the atomic oxygen effect. Experiments were constructed to investigate the atomic oxygen erosion effect of this material with a ground-based simulation facility, and as a function of temperature change. Masses and surface morphologies of the sample material before and after the experiments were compared. The reaction characteristics of the material in the facility and the impact of temperature change on atomic oxygen effect were acquired. In addition, the effect of ionic oxygen on the mass loss of the sample was qualitatively studied.
