Abstract

The integration of agricultural waste into polymer matrices offers sustainable pathways for developing eco-friendly composites. This study focuses on the mechanical behaviour of epoxy composites reinforced with corn cob ash (CCA) for sustainable applications. Using the hand lay-up method, the composites were fabricated with varying weight percentages of CCA (0%, 3%, 5%, and 10%). Microstructural, mechanical and physical properties were analysed, including tensile strength, hardness, impact strength, flexural strength, water absorption, and density. Results show that adding CCA influences the tensile and flexural properties with increase in the hardness and impact strength of epoxy. Presence of CCA in epoxy also reduced it water absorption property while increase in density was reported. The study shows the potential of CCA-reinforced epoxy composites for lightweight, sustainable applications thereby contributing to efficient waste utilization in engineering materials.
