摘要: 提出一种新的航天器用树脂基材料抗原子氧剥蚀的方法,即在航天器用树脂基材料中添加与原子氧不反应的超细颗粒材料,用于提高其抗原子氧剥蚀的性能.在制备出超细空心微珠颗粒增强的环氧树脂复合材料的基础上通过原子氧暴露实验,发现空心微珠的加入可以有效地提高环氧树脂抗原子氧剥蚀的性能.同时,空心微珠的表面性态对制备的复合材料抗原子氧剥蚀性能具有重要的影响,经过表面改性处理可以进一步提高复合材料抗原子氧剥蚀的性能.

Abstract: A new method of improving AO-resistant characteristics of spacecraft resins is proposed. The superfine particles, which are stable in AO environment, are filled in the spacecraft resin in order to improve the AO-resistant characteristics of the composite. The emphasis of this paper is filling superfine cenospheres in the spacecraft epoxy resin to produce the AO-resistant composite. Cenospheres/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 epoxy resin against AO erosion. In addition, the surface characters of cenospheres affected the AO-resistant characteristics of the composites, and the modification of cenospheres can obviously improve the AO-resistant characteristics of the composites.
