【Abstract】 Researches on the curing reaction and demoulding deformation are of great significance for the quality control of fiber reinforced polymer matrix composites. The theoretical models of resin transfer moulding processes were reviewed in three aspects:thermo-chemical model,cure kinetic model and residual stress model. Then the previous development of the numerical analysis was summarized in two aspects:the relationship among the curing reaction,cross-linking structure and physical-mechanical properties; the formation and development of internal stress and demoulding deformation. Finally,the prospects of the numerical analysis of the curing reaction and demoulding deformation were presented.更多还原
