A study of the problem of developing effective methods for predicting the determining characteristics of composite materials and structures under the influence of extreme environmental factors has been conducted. The formulated problems are investigated within the framework of refined variational formulations of inverse forecasting problems based on modern provisions of the kinetic theory of strength. A methodology for matching the parameters of mathematical and physical models at micro- and macro-levels has been developed, which made it possible to solve the problem of restoring the parameters of physical and chemical processes occurring at the micro-level and leading to destructive changes in composites and deterioration of their characteristics over time. An objective assessment of the parameters of destructive chemical reactions in composites based on the conducted physical experiments made it possible to construct effective generalized models of durability for a long-term period, as well as to conduct a constructive analysis of the influence of individual extreme factors on the durability of composites.
