摘要:The paper investigates the issue of promising ways to predict the durability of polymer composites under extreme conditions. A study of the possibility of predicting the durability of the material, based on the information obtained in the first years of operation. Based on themodern provisions of molecular kinetic theory (MKT), the issue ofmatching the defining parameters ofmathematical models calculated because of solving forecasting problems within the framework of the formulated variational formulation, considering the results of experimental measurements at the macro level, with the corresponding defining parameters of physical models describing molecular interactions at the microlevel, was investigated. The results of computational experiments are presented.
