The founder of the science of protecting materials from corrosion, aging and bio-damage in Soviet Russia is Georgy Vladimirovich Akimov, who created the infrastructure for climate testing of materials and products. Currently, his students and followers have discovered new directions for the development of climatic and microbiological tests – these are studies of the preservation of the properties of materials in complex technical systems under the influence of climatic factors, mold fungi, bacteria and operational loads using the most modern methods at the sites of the created network of climate test stations, as well as using modern regulatory documentation.

The residual stresses in carbon fiber reinforced plastic (CFRP), based on VTkU-2.200 carbon fiber and VSC-14 cyanate ester resin, modified by nanoscale additives (astralen) were studied. Natural exposure was performed in a moderately cold climate. The influence of nanoadditives on mechanical and physical CFRP’s properties after 9 months of climatic testing was studied using the following properties: three-point bending strength, compression strength, coefficient of linear thermal expansion, glass transition temperature and residual stresses parameters. The increase of residual stresses after climatic testing was revealed.
