OSTI ID:5920082
The effects of thermal environment and sorbed moisture on the mechanical performance and microscopic modes of deformation and failure of amine-cured epoxides are presented. The influence of thermal history and exposure to thermal spikes on free volume is discussed. Sorbed moisture is shown to lower the glass transition temperature and to degrade the mechanical properties of epoxies, while stress-induced damage in turn enhances subsequent moisture sorption. 6 figures.
