Abstract
The dynamic mechanical properties of polymerized epoxy resins have been studied over the 80—600°K. temperature region using an appratus which drives rodlike specimens in a transverse mode. Experimental results for the mechanical loss indicate several dispersion peaks throughout the temperature range. The dynamic modulus is found to be monotonically decreasing everywhere except near the 480—550°K. range. Effects of cure time, filler, and low dose irradiations are included in the investigation.
