A Study on the Mechanical and Water Absorption Properties of Granite Powder/Epoxy Toughened with PMMA and Fly Ash/Epoxy Toughened with PMMA Composites

Abstract

In this study, the properties of two particulate reinforced epoxy composites namely granite powder and fly ash have been assessed. An attempt has also been made to improve the pure matrix system epoxy resin using commercially available thermoplastic (polymethyl methacrylate). Pure blend matrix with different weight fractions of polymethyl methacrylate and epoxy are prepared and the blend matrix having the highest strength is selected for preparing composites. The composites are prepared with different weight percentages of granite powder and fly ash with the blend matrix, and their impact, compression, and water absorption properties are studied.
