The atomic oxygen (AO) of the upper atmosphere of the Earth is one of the most significant factors of space, causing damage to the surface of the spacecraft at altitudes of 200 to 800 km. Therefore, an urgent task is to study the characteristics of the impact of AA on the various materials used in space technology, including polymer materials, micro- and nanocomposites.
In this work was carried out mathematical and laboratory simulation of AK with polymeric materials and composites. Mathematical modeling of the process of erosion of the polymer material with a protective coating, and polymer composites with a filler, resistant to AK, conducted the Monte Carlo method, implemented in software GEANT3 complex. For laboratory simulation was used magnitoplazmodinamichesky oxygen plasma accelerator SINP, allowing a flow of fast neutral and ionized oxygen atoms. The irradiated samples were examined using an atomic force and electron microscopy.
