The effect of moisture content on the climatic resistance of polymer materials

The article provides the results of studying changes in the sorption and elastic-strength characteristics of polymer samples based on modified epoxy resin and various types of hardeners exposed to field climatic ageing. The effect of the exposure time on the change in the dependence of tensile strength and relative elongation at maximum load was established. The authors analyzed the effect of sorbed moisture on the change in elastic-strength properties of epoxy polymers.
