Abstract

Abstract: Influence of coffee bean natural filler reinforcement (5, 10, 15, 20, 25 and 30% mass fraction) on the mechanical properties of Epoxy LY556 composite, fabricated using compression moulding was analyzed in this work. The maximum mechanical properties were observed for 25% mass fraction of coffee bean natural filler composite. The fracture toughness increases with incorporation of coffee bean filler, due to uniform distribution of coffee bean in epoxy matrix and stress was disseminated equally. It also indicates that bonding between filler and matrix is better and 30% mass fraction filler reveals reduced wettability with the epoxy matrix in composite.
