In this paper presents the results of studying the regularities of formation of flexible film hybrid organo-inorganic polymeric materials based on epoxy oligomer ED-20, amine hardener PEPA (polyethylene polyamine) and a mixture of fillers: conductive - polyaniline (PANІ), doped with toluenesulfonic acid (TSA) with an additional magnetic impurity - highly dispersed magnetite (Fe3O4). which differ in structure and properties. The mechanical properties of composites and thermosetting polymer blends were studied by measuring the microhardness and ultimate microhardness on a Heppler consistometer. It was found that the introduction of fillers of different nature, as well as their mixtures significantly affects the microhardness of the formed polymer-polymer composites, and the nature of this effect depends largely on both the type of polymer and its content. Introduction to the reaction mixture of fillers in an amount of 5% of the mass. each leads to the formation of a hybrid structure, as evidenced by the emergence of a synergistic effect, which is that the action of one component is enhanced by another.
