Abstract

A method of improving AO(atomic oxygen)-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 protects the epoxy resin against AO erosion. In addition, the surface characters of cenospheres affect the AO-resistant characteristics of the composites, and the modification of cenospheres can obviously improve the AO-resistant characteristics of the composites.
