A study was conducted on the possibilities of using the methodology developed within the framework of variational formulations based on modern principles of the kinetic theory of strength (KTS) for effectively solving the problems of high-precision prediction of the defining characteristics of glass-reinforced plastics. Within the framework of variational formulations based on modern principles of the KTS, an optimal generalized durability model (GDM) was developed that takes into account the simultaneous influence of several destabilizing factors on the composite. The developed generalized durability model was used to effectively assess the durability of glass-reinforced plastics under the influence of extreme environmental factors. Based on the developed forecasting methodology, computational experiments were conducted within the framework of variational formulations, and optimal durability models were developed for composite materials such as fiberglass, which allow for the long-term prediction of the residual resource of fiberglass in the harsh continental climate of the Arctic and Subarctic zones.
