Green Reinforcement: Enhancing Aluminum-Based Composite Manufacturing with Waste Bagasse via Stir Casting Technique

Abstract

This study explores the use of waste bagasse ash as reinforcement in aluminum-based composites manufactured via stir casting. Bagasse ash particles were methodically introduced into molten aluminum at 700°C while being stirred at 500 rpm for 12 minutes to achieve uniform dispersion. The addition of 7.5% waste bagasse ash resulted in significant improvements across multiple mechanical properties. Tensile strength increased by 12.45%, hardness showed a remarkable enhancement of 21.32%, fatigue strength exhibited a substantial improvement of 19.45%, and wear resistance demonstrated a notable enhancement of 18.76%, all compared to the base composite. These findings highlight the effectiveness of utilizing waste bagasse ash as reinforcement, offering a sustainable approach to enhance the mechanical properties of aluminum-based composites. This research contributes to advancing eco-friendly manufacturing practices and underscores the potential of waste materials in optimizing material performance.
