Title: Microwave Assisted Crosslinking Process of Epoxy Resins
Abstract: The microwave technique was used intensively in the last few years for synthesis of organic compounds as an alternative method to the classical processes catalyzed by toxic substances. In the present paper the microwave technique was used to obtain composite materials based on the curing process of epoxy resin based on diglycidyl ether of bisphenol-A(DGEBA)with different amines as curing agents. Curing tests were performed using meta-phenylene diamine(mPDA), orto-tolidine(o-TOL)and 4,4′-diminodiphenylmethane(DDM)and DGEBA at different temperatures, curing agent concentrations and microwave powers. The curing process was followed by FT-IR Spectroscopy which gives the conversion versus time curves and therefore the curves of reaction rate against time. The results were compared with those obtained in classical processes thermally activated.
