Amine Terminated Polyetherimide/에폭시 수지 시스템의 경화공정연구와 파괴인성에 관한 연구
A Study on the Curing Behavior and Toughness of Amine Terminated Polyetherimide/Epoxy Resin System
초록
The cure kinetics of blends of epoxy (DGEBA:diglycidyl ether of bisphenol A)/anhydride (NMA:nadic methyl anhydride) resin with synthesized amino terminated polyetherimide (AT-PEI) were studied using differential scanning calorimetry (DSC) and Dynamic Mechanical Analysizer(DMA) under isothermal condition to determine the reaction parameters and gel-vitrification behavior. The fracture toughness of AT-PEI 20phr/epoxy resin system was improved over 224% and 42.5% more than neat epoxy resin and commercial PEI/Epoxy Resin System.
