Abstract
Hybrid composites are gaining increasing interest in the development of aluminium metal matrix (AMCs) for various industrial applications owing to their ability to integrate multiple functionalities within a single material matrix with enhanced physio-mechanical properties as opposed to single-fibre reinforced composites. Green plantain peel ash (GPPA) is an agricultural waste with potential for reinforcement purposes. However, no study has investigated GPPA natural filler as a reinforcement for AMCs. This study, therefore, aims at assessing the influence of variations in GPPA particles and alumina as reinforcements in the fabrication of hybrid composites using Al-Mg-Si alloy as a matrix. This study also reassessed the chemical composition of the GPPA particles and investigated their mechanical properties. However, enhanced mechanical properties, including hardness, tensile strength, and ductility, were observed at varying weight ratios. Results obtained in this study suggest a promising potential application of GPPA particulates as complementing reinforcements in the production of lightweight, strong, and high-performance AMCs well-suited for engineering, aerospace, construction, and packaging applications.
