Abstract
Creep tests of an epoxy resin during bending and irradiation have been carr ied out to investigate the synergistic effects of radiation and stress on m echanical properties of the resin. Simultaneous application of stress and i rradiation on the epoxy resin enhanced creep rates in comparison with the a pplication of stress on an irradiated sample. In order to clarify the mecha nism of the radiation-induced creep, measurements of solvent swelling of sp ecimens have been performed. The swelling increased with the dose and the i ncrease of the swelling corresponds to the increase of the chain scission. The mechanism of increased deformation of the resin during irradiation is p roposed to be caused by increased chain scission following the release of t he local strain energy.
