Hydroxyl terminated polyurethane (HTPU) in different proportions has been incorporated into DGEBA based epoxy resin, cured with triethylene tetramine. Composites are developed using varying weight fractions of silane coupling agent treated granite powder as reinforcement in pure and toughened epoxy resin. Various physico-mechanical properties such as tensile and flexural behavior, density, and void content have been determined. Studies revealed that toughened resin composites enhance the properties compared to neat matrix.
