The influence of climatic factors on properties of basalt and fiberglass made by the infusion method has been studied by sequential laying some reinforcing material on the mold, impregnating with a three-component epoxy binder, consisting of ED-22, Iso-MTHFA, Agidol 53, and curing at a temperature of 160±2 °С, within 4 hours. Full-scale climatic tests of basalt fiber and fiberglass in a very cold climate zone demonstrated their resistance to climatic influences, which is confirmed by a high level of preservation of their strength parameters. Exposure of basalt fiber to natural conditions led to a decrease in tensile strength by 14% and an increase in flexural strength by 18%. The values of fiberglass increased by 9% (ultimate tensile strength) and 22% (ultimate tensile strength). Porosity measurements showed that after exposure, basalt-textolite samples increased open porosity by 62%, while glass-textolite samples decreased by 39%. After climatic tests, an increase in the average range of the inhomogeneities (Ra) of the surface of the basalt-textolite up to 0.48 μm (initial — 0.70 μm, after exposure — 1.18 μm). In fiberglass, the average roughness increases by 4 times after exposure (initial — 1.03 μm, after exposure — 4.08 μm).
