Experimental Studies on Epoxy-Amine System Using Microwave and Conventional Curing Approaches

Article Preview

Abstract:

In this present work attempts have been made to study the difference between microwave heating and conventional thermal heating in curing the epoxy-amine system of di-glycidyl ether bisphenol-A(DGEBA) with the curing agent of 4,4′Diamino diphenyl methane(DDM). Curing behaviors and mechanical properties of the system were studied through a number of experiments. Differential scanning calorimetry (DSC) technique was implemented to measure the glass transition temperature and kinetic parameters, and fourier transform infrared spectroscopy(FT-IR) was used to analyse the cure reaction mechanism of the resin system. Finally, microstructure of microwave-cured materials was also studied by using a scanning electron microscope(SEM) in order to analyze the morphology of cured specimens.
