STUDY ON THE PROPERTY OF EPOXY/IMIDAZOLE CURING SYSTEM

Zheng Yaping, Ning Rongchang, Dang Xiaolong, Qiao Shengru (Department of Chemical Engineering,Northwestem Polytechnical University, Xi'an 710072)  
Using diglycidyl 4,5-epoxycyclohexane 1 , 2-dicarboxylate(TDE - 85 resin) as matrix and 2-ethyl-4-methyl imidazole as curing agent, the curing method was 80℃/2h+110℃/2h+150℃/2h+180℃/2h by DTA analysis. As a result, ΔE was 55.59 kJ/mol, n was 0.921 . The modulus was up to 5.26 GPa, it could be used in advanced composites.
