Abstract

The effects of impregnation on the dynamic mechanical properties of yellow-poplar (Liriodendron tulipifera L.) sapwood have been investigated for stoichiometric and nonstoichiometric mixtures of a diglycidyl ether of bisphenol-A based epoxy resin and meta-phenylenediamine. For the temperature range from 0 to 100 C, the measured values for the dynamic modulus of these wood-polymer composites exceeded the predicted values based upon the rule of mixtures. In contrast, the actual results for the internal friction values were significantly lower than those predicted by the rule of mixtures. Modification of this equation for strain energy sharing effects resulted in much improved estimates for the internal friction values, however.
