Dynamic properties of samples of an epoxy resin unfilled and filled with glass beads subjected to extensional creep were studied. The investigated epoxy resin was EPON 826 cured with diethylenetriamine(DETA). The real modulus of both the unfilled and filled resins decreased during creep of the samples. The extent of the decrease was higher in the filled resin, presumably due to wetting-dewetting processes occurring in the filler-matrix interphase. In most cases, the loss modulus also decreased during the creep process of the investigated materials. In cases when the load was removed, most of the initial dynamic properties of the samples recovered after the materials relaxed from the applied load. A correlation between the dynamic properties of the investigated material and the axial strain during creep was found.
