Viscoelastic Properties of Epoxy Resin Materials Filled with Ground Calcium Carbonate
Abstract: The study of viscoelastic properties of polymers dynamic mechanical method is of great theoretical and practical importance. Dynamic mechanical properties, especially mechanical losses, very sensitive to all types of thermal transitions, relaxation processes, structural heterogeneities and characteristics of morphological structures of multiphase systems such as partially-crystalline polymers, mixtures of polymers and filled polymer compositions. In a wide temperature interval investigated the dynamic mechanical properties of composite materials based on epoxy polymers filled with ground calcium carbonate, depending on the size and concentration of filler, mode of curing and exposure of the aquatic environment. It is shown that the filling of the composition contributes to the increase in dynamic modulus of elasticity and modulus of losses and the temperatures corresponding to the maximum values of modulus and loss tangent of mechanical losses.
Keywords: epoxy composite materials, ground calcium carbonate, viscoelastic properties, dynamic mechanical method, mode of curing.
