Abstract

Epoxy resin based on diglycidyl ether of bisphenol A and varying content of hydroxyl terminated polybutadiene (HTPB) were cured using a polyamide curing agent. The ultimate aim of the study was to modify the epoxy matrix by liquid rubber so as to improve its toughness. Tensile, flexural, and impact properties were evaluated. The morphological evolution of the toughened networks was examined by scanning electron microscope, and the observations were used effectively to explain the obtained impact properties.
