METHOD OF ESTIMATION OF SPACE MATERIALS STABILITY TO IMPACT OF COSMIC SPACE FACTORS

摘要

FIELD: testing equipment.;SUBSTANCE: invention relates to the field of testing polymeric materials that are included into the structure of space crafts (SC). In the proposed method material specimens are exposed within a specified period of time on the surface of SC, then are placed in a container which, in turn, is placed in a transport container (zip lock in space) and they are return to Earth. In a vacuum chamber with a controlled inert atmosphere, the containers are opened and specimens are taken from them, each of which is placed in a separate sealed tank. Then, under laboratory conditions, changes in the properties of specimen materials are determined. The pressure of inert atmosphere in the vacuum chamber is maintained above the ambient pressure.;EFFECT: increasing the reliability of test results by practical exclusion of the influence of the Earth's atmosphere on them.;1 dwg
