Abstract

In our torsional dilatometry study, we have examined the time scales for the physical ageing process and for the viscoelastic relaxation of a model epoxy netweork subjected to torsional strains, after up and down temperature jumps. We have also measured the contribution of thermally induced normal forces to the volume recovery time scale. These results present an interesting twist on the prior observation of Santore et al. of differing time-scales for different processes (i.e. volumetric, viscoelastic, etc.) in glassy polymers. Here we discuss the significance of these results and also present comparisons with work in which the sample was unloaded throughout the testing. Possible experimental articrafts are examined, and we discuss their relevance to prior observations.
