摘   要：

A review of studies on aging of basalt plastics (BPs) under natural climatic conditions is presented. The mechanisms of aging are analyzed based on the results of deformation and strength measurements, dynamic mechanical analysis, linear dilatometry, moisture sorption and diffusion, microscopy, and other methods sensitive to physicochemical transformations in polymer matrices of BPs and at the polymer–filler interface. The role of internal stresses in comparing BP aging in different climatic zones has been determined. The influence of the dominant climatic factors (temperature and thermal cycles, moisture, ultraviolet radiation) on the mechanical parameters of the BP is considered. New results are presented on the durability of BP reinforcement when exposed under static bending loads in open conditions of a moderately warm climate.
