Composite materials are becoming the most preferred structural material because of its advantage of tailor-made properties. Minimising Stress Concentration Effect (SCF) at geometric discontinuities is very important as these regions are failure initiators. Hence in this study an attempt has been made minimize SCF in Polymer matrix composite by improving polymerization. Three heat sources were compared for this study, which includes conventional hot air, microwave and infrared heating at 140ºC for 2 hours. It was found that, selection of heating source for post curing has a considerable effect on strength of the laminates Keywords: Post curing, Stress Concentration effect, Glass Fibre Reinforcement Composites, Heating Source, Infrared, Microwave, Hot air heating
