In the recent years we can evidence the increase in the range of polymer composites used as protective and decorative coatings of building structures. The high resistance to the effects of different aggressive factors results in great potential of polymer materials application, that’s why interest in them continuously increases in many industrial fields. At the present moment multicomponent composite materials based of epoxy binders are widely used. We present the research results of micromarble granulometric composition and the degree of filling influence on the change of physical and mechanical characteristics of polymer composites based on epoxy resins. In the article graphic dependences of the changes of density, ultimate compressive and tensile strength and maximum deflection depending on fractional composition and the mass fraction of the micromarble are shown. We have identified the compositions of filled epoxy composites with the most optimal set of properties. As a result of the conducted investigations we made a conclusion that micromarble is a promising filler for epoxy composites, application of which allows essentially reducing the consumption of polymer binder and obtaining composites which have equal physical and mechanical characteristics to the test unfilled composition.
