Abstract

The present paper investigates the effect of adding silica nanoparticles to an anhydride-cured epoxy polymer. The formation of 'hybrid' epoxy polymers, containing both silica nanoparticles and carboxyl-Terminated butadiene-Acrylonitrile (CTBNrubber microparticles, is also discussed. The structure/property relationships are considered, with an emphasis on the toughness and the toughening mechanisms. The present work also extends an existing model to predict the toughening effect of the nanoparticles in a thermoset polymer. There was excellent agreement between the predictions and the experimental data for the epoxy containing the silica nanoparticles.
