SIMULATION OF THE EFFECT OF FULL-SCALE EXPOSURE DURATION AND INTENSITY OF ACTINOMETRIC PARAMETERS ON CHANGE OF PHYSICAL AND MECHANICAL PROPERTIES OF EPOXY POLYMERS TAKING INTO ACCOUNT THEIR MOISTURE CONTENT
Abstract
The article presents the results of the analysis of the climatic resistance of epoxy polymers based on the modified Etal-247 resin cured by Etal-45M exposed to natural climatic factors in a temperate continental climate. We reveal the influence of the moisture state, duration of climatic aging and intensity of actinometric parameters on the change in the tensile strength and modulus of elasticity in tension, elongation at maximum load and rupture. We proposed mathematical models and determined their numerical coefficients, which make it possible to describe with a high degree of reliability the change in the elastic-strength parameters of the polymer under study depending on moisture content of the samples, duration of full-scale exposure, and intensity of actinometric parameters.
