摘要

The effects of physical aging on the dynamic mechanical properties of NEPE-5 wererndetermined by using dynamic mechanical analysis (DMA) .The change of the dynamicrnmechanical properties was analyzed as the main mode of failure. The inflection of the verticalrnshift factors which were obtained from the superposition master curves, was considered as thernaging rate and the temperature dependence of aging rate, i.e., activation energy was obtainedrnfrom Time-Temperature Superposition curves. By using the "point-slope method", the physicalrnaging life can be estimated.
