Abstract

Changes in the dynamic properties of unfilled and filled cured polyester resins during extensional creep were measured with the aid of a modified torsion pendulum. Glass beads were used as filler. The decrease in the real shear modulus during creep is attributed mainly to a debonding process. Dewetting-rewetting processes reflected by modulus changes, were discussed on the basis of a theory of Takahashiet al. Voigt-Kelvin rheological models were used to characterize the modulus and the creep compliance recoveries after load release.
