Influence of a very cold climate on properties of basalt and glass textolites made by an infusion method by successively laying a reinforcing material on a mold and impregnating with a three-component epoxy binder is studied. Full-scale climatic tests at an open proving ground during 2 years led to a decrease of ultimate tensile strength by 14% and an increase of ultimate bending strength by 18% for the basalt textolite, the increase of the ultimate tensile strength by 9% and the ultimate bending strength by 22% for the glass textolite. Conducted studies of changes of surface relief showed insignificant variations of average amplitude of inhomogeneities up to 0.4 μm for the basalt textolite and up to 4 μm for the glass textolite. The conducted studies of these materials demonstrated their resistance to the climatic influences in a region of the very cold climates, which is confirmed by a high level of preservation of their strength parameters.
