dc.descriptionThe high cost and negative environmental impact of traditionally made aluminium metal matrix composites (AMMC) need their replacement with ecofriendly materials with improved mechanical characteristics. The repurposing of agricultural waste in innovative materials is critical to achieving a sustainable society. This study utilized AA6061/chitosan at sieve size of 90μm created via modified stir casting at weight proportions of 3, 6, 9, and 12 wt. %. The produced composites reached a maximum hardness of 60.2 HRB at 9wt. % chitosan, comparable to a 2.36 % improvement in AA6061 hardness, 57.4 HRB. Similarly, tensile strength increased with increasing chitosan particles, from 83.07MPa for the unreinforced alloy to a maximum of 114.92MPa for 12 wt. % AA6061 reinforcement with chitosan. The samples' XRD revealed clear evidence of Hydroxyapatite, Ca10(PO4)6(OH)2, a component of teeth and bones that provides strength. The corrosion characteristics findings reveal that AA6061+9 wt. % chitosan has the lowest corrosion rate of all the samples. In addition, the microstructure of AA6061 with chitosan strains of reinforcement was observed in the AA6061/3wt. % SEM, eventually filling grain boundaries of the metal with increasing reinforcements to provide evenly distributed fibrous links connecting AA6061 grain structure at 6wt. % and 9wt. % reinforcement in the micrograph
