Abstract

The paper presents data on increasing the resistance to atomic oxygen of a polymer composite based on polyimide and tungsten oxide WO2 by adding crystalline silicon. As an additive to the composite, finely dispersed crystalline silicon of the KR-00 grade 40 μm with a specific surface area of 5 m2/g was used. Tests simulating the effect of atomic oxygen on composites in space were carried out by treating polyimide composites with oxygen plasma. The energy of atoms and oxygen molecules reached 35 eV. Composites of optimal composition with a content of 65 wt% WO2 were tested. The data on the mass loss of composites after treatment with oxygen plasma are presented, and the microstructure of the surface of the composites is studied. The introduction of an additive of crystalline silicon in an amount of 1 wt% allows reducing the mass loss of the composite under the influence of an oxygen plasma flow by 31.6%.
