Based on the detailed researching in the curing reactivity
reaction mechanism
dynamic mechanical behavior and impact strength for E51/dicy curing system modified with LCEU PPG containing both the flexible spacer chain and rigid liquid crystal unit chain
the morphology of the fracture surface was observed by SEM.The relationships between the morphologies and dynamic mechanical behavior
impact strengths were also discussed.The results reveal that there exist two phase microstructure for the modified curing systems.This leads to the significant improvenment in impact strength.
