Effect of Fillers Loading on the Mechanical Properties of Hardwood Sawdust/Oil Bean Shell Reinforced Epoxy Hybrid Composites

Authors(2) :-Engr. Oghenerukevwe Prosper, Hilary Uguru

There is an increasing interest in development of bio-composite materials and their applications in various fields, to replace synthetic fiber reinforced composites. In this study, mechanical properties such as tensile characteristics, flexural characteristics, and compressive characteristics of hardwood sawdust (HSD) and oil bean pod shell (OBPS) hybrid composites in epoxy (EP) matrix were investigated as a function of filler loading. Hybridized composite sample was prepared with 20, 30, 40, 50, and 60% reinforcements of sawdust and oil bean pod shell particulate (the fillers) in the ratio of 1:1 and cured for 21 days. The prepared composites were tested according to ASTM standards, and the results showed that the filler reinforcement had strong effect on the tensile, compressive and flexural characteristics of the composite board. The tensile strength, transverse rupture strength, Bending Modulus and compressive strength increased progressively up to 50 % filler loading, before their values dropped at 60 % filler loading; while percentage elongation at fracture only increased to 40 % before it started decreasing. The results of this study showed that composite could be successfully developed using HSD, OBPS and epoxy would be a substitute for wood-based material in many applications.
