A hygrothermal thermoset resin-cure model has been developed, in conjunction with experimental data, for the e-beam processing of composites in terms of e-beam dose-time sequences in order to achieve full resin cure, minimum residual stresses and avoidance of moisture-induced cavitation within the resin system. This paper, as Part II of this study, summarizes dynamic characteristics of Tg -σy -Pv rise and their modeling procedures together with an attempt at optimizing the e-beam-cure process. The modeling procedure of e-beam-induced cure kinetics, and the results of local temperature and degree of cure rise within the sample as a function of dose were presented in Part I.
