Using the method of the structural analysis, IR and ER spectroscopy as well as TBA method and investigation of the residual stresses it was found, that while introducing the metal oxides dispersions, forming of the peroxide matrix structure is of special characters, which makes possible to find the nature of the phenomena relaxation in the filled composite and to propose the temperature regimes of hardening which allow to realize the potential possibilities of the epoxide matrix under composite forming with the preliminary desired operating propertie
