Abstract Results of simulation tests of protective and functional coatings influence on resistance of polymeric constructional spacecraft materials to impact of atomic oxygen with fluences up to 3.5 × 1022 cm-2 are presented. It was demonstrated that oxygen plasma beams can be used in accelerated tests of carbon-based and polymeric materials (with the exception of fluorinated hydrocarbons) to evaluate their resistance to the AO impact in LEO. For the unprotected materials sharp fall of mechanical properties and optical characteristics deterioration were observed. Application of protective coatings had shown to reduce their degradation.
