USE SILICON-CONTAINING STRUCTURES TO FORM A COMPOSITE WITH INCREASED RESISTANCE TO ATOMIC OXYGEN
The analysis of composite polymeric materials used in outer space. It was shown that atomic oxygen has a serious negative impact on the surface layer of the materials. It was found that to improve the stability of the composites to the atomic oxygen is necessary to introduce in their composition of silicon structures. For the experiment was used as a binder  – high impact polystyrene matrix, and as a protective filling  – orthosilicic acid. Studies on the effect of atomic oxygen in the synthesized composites were carried out atSkobeltsyn institute of nuclear physics Iomonosov Moscow state university, in a finding of material simulating the maximum at an altitude of 450 km above sea level. It is found that the material of pure high impact polystyrene much more susceptible to atomic oxygen degradation of the surface compared to composites containing orthosilicic acid.
