Abstract
Composites reinforced with natural materials play a vital role in engineering applications, like the fabrication of automobile parts, furniture making, etc. The objective of this present research is to determine the flexural properties (flexural strength, flexural energy) of oil bean pod shell (OBPS) and hardwood sawdust (SD) reinforced composite in epoxy matrix, at different filler loading. Hybridized composite samples used for this research were prepared with 20, 25, 30, 35, and 40% filler (SD and OBPS in the ratio of 1:1) reinforcements in the ratio of 1:1. The flexural test was conducted on the samples according to ASTM D-790, using the Universal Testing Machine. From the results obtained, the fillers loading had significant (P ≤0.05) effect on the three flexural properties studied. The flexural strength increased from 33.44 to 67.65 MPa, the flexural energy increased 53.1%, while the flexural yield strength increased from 23.58 to 55.4 MPa. The results obtained from this research will be helpful the automobile and construction companies.

The Epoxy LY556 resin and HY951 hardener used to prepare the composite matrix were purchased from a chemical shop at Onitsha, Anambra state, Nigeria
Summary
A composites are produced by combining two or more materials with different together. The combined materials work together to give the composite unique properties. Natural composites are made from biomaterials (animals and plants) parts. Natural materials are gaining progressive account, since they are renewable, environmentally friendly, and biodegradable. They are fast becoming starting material for industrial and civil engineering applications, such as; textiles, composites, pulp and paper, building components, etc. Natural fibres reinforced composites combine acceptable mechanical properties with a low density (Yang et al, 2004; Uguru and Uyeri, 2018). Mechanical properties of natural fibre reinforced composites are comparable to those of synthesis fibre
