For epoxy polymer compositions, the influence of the duration of treatment with electromagnetic ultra-high-frequency radiation on the amount of released thermal energy is determined in the article. The optimum duration of exposure of the epoxypolymer compositions in the electromagnetic field at the first stage and the temperature to which it is necessary to cool the composition to obtain the optimum amount of thermal energy have been determined. The dynamics of temperature change in time on the surface of the compositions was investigated depending on the volume of the samples, their shape and the duration of processing. Fractograms of destruction of epoxy polymers structured by cyclic processing under the action of microwave electromagnetic radiation have been investigated. The expediency of using a cyclic mode of treatment of the compositions in an electromagnetic field to intensify the structuring process of epoxy polymers is shown.
