The aim of this study is to identify the effect of using various healing temperatures ranging from 120oC to 180oC with temperature interval of 100C on self-healing resin system containing diglycidyl ether of bisphenol-A (DGEBA), the hardener nadic methyl anhydride (NMA), the catalyst benzylmethylamine (BDMA) and poly(bisphenol-A-co-epichlorohydrin) (PDGEBA) as healing agent. The effects of different healing temperatures on the resin systems were investigated by means of Fourier-transform Infrared Spectrometer (FTIR), Dynamic Mechanical Thermal Analysis (DMTA), and izod test. Optical image of the sample morphology was observed using optical microscope. Healing efficiencies (HE) were evaluated using izod test and the optimum healing temperature of 160oC was obtained within the third healing cycles with HE 37%. The results indicate that the healing temperature affected the physical aging and the chemical reaction between the secondary hydroxyl group and carboxyl group occurred at high temperature of ≥180oC.
