Abstract
The influence of solar radiation as a factor of climatic impact on polymer composite materials has not been studied enough. Under the influence of the ultraviolet component of solar radiation, even in cold climates, the surface of materials undergoes destruction and micro-cracking. This destruction is enhanced by capillary condensation of moisture, which at low climatic temperatures increases internal stresses, leading to the formation of microcracks, because of which the strength of polymer composite materials decreases. An algorithm for modelling of polymer composite material aging in cold climates and for identification of significant environmental factors is proposed. Expansion and systematization of experimental data on properties of polymer composite materials exposed to various climatic conditions, including in a cold climate, are anticipated to develop application of extrapolation methods.
