Studies on Tensile and Flexural Properties of Epoxy Toughened with PMMA/Granite Powder and Epoxy Toughened with PMMA/Fly Ash Composites

Epoxy is toughened with polymethylmethacrylate (PMMA) and different percent weights of granite powder and fly ash are added to this matrix. The tensile and flexural strengths of these composites are determined. The variation of tensile and flexural strengths with granite powder and fly ash content is studied. For comparison, epoxy is also used as the matrix. The tensile and flexural strengths increased with PMMA content up to 4% (w/w) in the composites. The granite powder composites showed better properties than fly ash composites.
