This paper presents the study of resistance to atomic oxygen-based composites samples polyimide matrix using as fillers nanoparticles following: Al2O3 (corundum) with average particle size 40-80 nm; TiO2 (rutile) size of 30-40 nm and a WC (tungsten carbide) size of 70-300 nm. In the latter case, as we can see, the maximum size of the particles used is slightly higher than the upper limit of the conventional nano. Samples of each composite of said fillers were made into films of thickness ~ 50 microns for the same mass of filler content equal to 3%. Samples were exposed to a flow of atomic oxygen on magnitoplazmodinamicheskom accelerator SINP on mteodike described in . After irradiation, were measured by atomic oxygen and the mass loss of samples was conducted their surface examination using a scanning electron microscope, which also allow to determine the elemental composition of the samples at predetermined areas of the surface.
