Abstract
The conversion of bio-agricultural wastes into composite material for engineering applications is a strategy to add
more value in waste utilization and help in the composites with epoxy resin and 10 wt.% NaOH treated Khaya ivorensis dust and
egg shell particles were prepared by open molding technique. Tensile strength, flexural strength and hardness tests were carried
out to evaluate the composite mechanical properties. The results showed that the tensile and flexural strengths increase with
addition of reinforcement materials. The composite sample with 3 wt.% wood dust and 10 wt.% egg shell particles displayed
highest tensile strength of 34.87 MPa, while the composite sample with 10 wt.% wood dust and 10 wt.% egg shell particles have
highest flexural strength. Hardness value of the composite increases with addition of reinforcement materials and maximum at
5 wt.% wood dust and 10 wt.% egg shell particles. In addition, water absorption characteristics of the composite increases with
increasing percentage of wood dust. Optimum composition of wood dust and egg shell can be used to produce polymer matrix
composites with good mechanical properties.
