The results of the microwave radiation influence of the electromagnetic field oscillation frequency of 2450 MHz on the process of curing thermosetting epoxy resins, which are used as a binder in the production of polymer composite materials based on basalt, glass and carbon fibers, are presented. It is shown that the density of the cured thermosetting epoxy resin using microwave radiation becomes higher compared to traditional methods. The maximum density of thermosetting epoxy resins is achieved by uniform microwave heating.
