Dynamic elastic modulus and internal friction of a Portland cement (Type I) mortar system impregnated with an epoxy resin system and with methyl methacrylate were measured in the temperature range of 100 to 450°K by use of a free‐free resonance technique. Dynamic modulus values were found to increase greatly compared to controls, especially at lower (<300°K) temperatures. Above 320°K the dynamic moduli of polymer‐impregnated mortars exhibited a sharp decrease toward control values. Low temperature damping maxima of the composites differed significantly from those of the constituent phases.
