Compression,Impact and Fractographic Studies on Granite Powder-Filled HTPU-Toughened Epoxy Composite

Abstract

Hydroxyl-terminated polyurethane (HTPU) in different proportions has been incorporated into DGEBA-based epoxy resin, and 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 mechanical properties, such as compression and impact behavior, have been determined. Also, fractographic studies of the composites have been carried out. Studies revealed that toughened resin composites enhance the properties, compared to neat matrix.
