TOUGHENING OF EPOXY USING BITUMEN AS MODIFIER

Abstract

Abstract: This article describes the toughening effect on epoxy using bitumen as the modifier. Impact properties,tensile properties and thermal properties with different bitumen contents were analyzed. With the addition of only 2% bitumen to epoxy, maximum improvements of 120% were obtained for impact energy. The addition of bitumen had no significant effect on tensile properties of epoxy. FTIR result showed that there was no chemical reaction between epoxy and bitumen. DSC analysis of the hybrid showed that the Tg of epoxy decreases significantly after 2% bitumen.

Key words: epoxy, toughening, bitumen
