Abstract

A positron annihilation lifetime spectrometer has been built to study the effects of shear strain and physical aging on the unoccupied volume in DGEBA/PPO glassy epoxy. Lifetime spectra were obtained in situ for a sample deformed in simple shear. Preliminary results on the effects of aging, temperature, and shear deformation on the τ3 lifetime of positrons are reported.
