Development of hybrid aluminium alloy composites modified with locally sourced environmental wastes

ABSTRACT

Towards developing green composite through waste recycling, the main objective of this work was to produce an Al6113 hybrid composite via stir casting with a combination of two different reinforcements, such as waste glass powder (WGP) and snail shell ash (SSA) particles. Samples mixtures were prepared and labelled as groups A, B, C, and D. Group A samples were developed with the blend of 2, 4, 6, 8, and 10 wt% WGP and 3 wt% constant dose of SSA particles. Groups B, C, and D samples were prepared with the blend of the same proportion of WGP and 6, 9, and 12 wt% SSA. The mechanical properties of the composites were examined to determine the effect of reinforcement combination on the composites. It was observed that WGP inclusion enhanced tensile, impact, fracture, flexural, and compressive strength when combined with 3, 6, and 9 wt% SSA. Meanwhile, the blend of the WGP with 12 wt% SSA resulted in depreciation in strength. It is deduced that the properties of the composite can be improved by the dual presence of WGP and SSA in the proportions of 2–6 wt% WGP and 3–9 wt% SSA.
