It is shown that the physical and mechanical properties of polymer composite materials can be improved by various activation methods. This article studied the structural changes that occur in polymeric materials under the influence of an electromagnetic field of various strengths. The purpose of the work was to establish the magnetic treatment effect on the physical and mechanical properties of polymer composites based on epoxy binders. In the research tasks, the experiments to study unfilled and filled compositions, the establishment of microhardness indices over the cross section of the samples made under the influence of an electromagnetic field of different strengths, were carried out. The composites based on an epoxy binder grade ED - 20 were considered as an object of research. Polyethylene polyamine served as a curing agent of the composites. Pyrite cinders served as filler in the composites. As a result of the research, the rational modes of the materials’ magnetic processing were established. The improved properties are possessed by the epoxy composites activated at a current of 9 A, lasting 9 hours.
