Study on Curing reaction and Mechanical Properties of Liquid Crystalline p-SBPEPB/BPAER/MeTHPA System

摘要

The cure kinetics for bisphenol A epoxy resin (BPAER) modified by liquid crystalline Sulfonyl bis(4,1-phenylene)bis[4-(2,3-epoxypropyloxy)benzoate](p-SBPEPB), with3-methyl-tetrahy drophthalic anhydride (MeTHPA) as a curing agent, were investigated by nonisothermal differential scanning calorimetry (DSC) method. The effect of the different liquid crystalline contents and activation energy (E_a) on curing reaction were discussed. The glass transition temperature (T_g) and mechanical property were charactered, The results show that the better content is about 10wt%.
