摘要: 采用一种新的抗原子氧剥蚀技术来提高航天器用玻璃纤维/环氧树脂复合材料抗原子氧剥蚀的性能,即在玻璃纤维/环氧树脂中加入不与原子氧反应的超细空心微珠颗粒制备出能抗原子氧剥蚀的复合材料.通过对空心微珠/玻璃纤维/环氧树脂复合材料的制备和原子氧剥蚀效应地面模拟试验,发现空心微珠的加入可以有效提高玻璃纤维/环氧树脂抗原子氧剥蚀的性能,在60?h的原子氧试验中,加有空心微珠的复合材料的原子氧剥蚀率可以减小到未添加空心微珠材料时的11%.

Abstract: A new technology was adopted to improve AO-resistant characteristics of spacecraft composites. The superfine cenospheres, which were stable in AO environment, were filled in the epoxy matrix in order to produce the AO-resistant glass fiber/epoxy resin composite. Cenospheres/glass fiber/epoxy resin composites were prepared and the AO exposure test was conducted in ground-based AO effects simulation facility. It was found that the filling of cenospheres effectually protected the glass fiber/epoxy resin against AO erosion. After the AO exposure test of 60 h, the erosion yield of the composite with cenosphere fillers can decrease to 11% of the composite without cenosphere fillers.
