Characterization of Oil Bean (Okpeye) Husk Reinforced Polyester Resin (Composite Material Development)

Abstract

Composite materials have shown great versatility and play a crucial role in addressing engineering challenges, environmental pollution, and greenhouse gas problems. This project aims to develop and characterize a novel composite material made from oil bean (okpeye) husk, evaluating its mechanical properties and potential applications. The oil bean husk was processed into coarse and fine particles (flake and particulate forms) and subsequently reinforced in a polyester resin matrix. Key mechanical properties determined include maximum tensile strength values of 7.642 N/mm² for coarse texture and 6.398 N/mm² for fine texture, impact strengths of 3.15 ft-lbs and 5.05 ft-lbs, and toughness values of 0.575 kgfm/cm² and 0.945 kgfm/cm² for coarse and fine textures, respectively. Given its high availability, low cost, and favorable mechanical properties, the composite offers a viable alternative for use in the automotive industry, particularly in applications like dashboards. Future research could further optimize its performance for broader industrial applications.
