Abstract
Isophthalic unsaturated polyester resins are used widely as the thermoset matrix for high quality fibre-reinforced composites. However, they suffer from low impact resistance. Substantial enhancement of the fracture toughness of brittle polymers may be achieved by dispersing rubber particles in the polymer matrix. In this study, elastomers bearing reactive functional groups, viz. hydroxy terminated polybutadiene (HTPB), hydroxy terminated natural rubber (HTNR), epoxidised natural rubber (ENR), amino terminated natural rubber (ATNR), carboxy terminated butadiene-acrylonitrile rubber (CTBN) and maleated nitrile rubber (MA-g-NBR) were blended with isophthalic resin. The physical properties of the cured blends were compared with those of the unmodified resin. The elastomers bearing reactive functional groups showed compatibility with the resin and improved the toughness and impact resistance of the cured resin substantially. The performance of maleic anhydride-grafted nitrile rubber was found to be far superior to all other rubbers considered in this investigation. An improvement in toughness, impact resistance and tensile strength has been achieved without seriously affecting any other property.
