The dynamical mechanical properties of epoxy composites filled with different amounts of quartz powder were investigated. The loss tangent and the storage Young's modulus were measured at frequencies between 5 and 323 Hz with a tension-compression device, from room temperature up to 460 K. The glass transition temperature and the apparent activation energy increase with filler content. The dynamic modulus also increases with quartz powder percentages. Test frequency and temperature dependence of these results were analyzed within the scope of models presented in the literature for composite materials.
