Research about the influence of a cold climate on the structure and elastic-strength properties of polymer composite materials is carried out in order to predict the kinetics of the development of degradation of the surface of a composite material during climatic aging, as well as to develop recommendations on methods for protecting existing and creating new promising polymer composite materials. The exposure of samples was carried out at the open site of the test site of the Institute of Physics and Technology Problems of the North for 24 and 48 months. As markers of degradation of the polymer binder in basalt and fiberglass textolites, we used the index of the average range of surface inhomogeneities, open porosity, density, absorption bands of IR spectra, and the index of equilibrium moisture content, diffusion coefficient before and after exposure to climatic factors.
