Abstract : Research was conducted on Epoxy resins, the low temperature relaxation spectra of six epoxy resins was determined via thermally stimulated depolarization measurements. The effect of cross-linking and aging upon physical properties and fracture phenomena has been ascertained for the epoxy resin systems diglycidyl ether of butanediol, DGEB and 4-4' diaminodiphenyl sulfone, DDS.
