dc.descriptionThis study explores the mechanical behaviours of AA7075/chitosan composite at a mesh size of 90μm formed through percentage range of 3, 6, 9, and 12 wt. % by stir casting method. SEM revealed existence of grain at the borderline of the matrix as increased in reinforcing agent resulted to evenly dispersal of fibre links in the micrograph. XRD analysis showed existence of Hydroxyapatite, Ca10(PO4)6(OH)2, as seen by many high-intensity peaks in the diffract gram of the dominant crystal. The wear rate of the samples is seen to be increasing from the control, peaking at 1.78 % at AA7075+9 wt. % chitosan before dropping by 0.04 % at AA7075+12 wt. % chitosan. The corrosion study revealed that AA7075+9 wt. % chitosan exhibits minimal corrosion rate in comparison to other matrixes. The findings shows that chitosan-reinforced AMMC can be produced using a cost-effective stir casting process while still meeting design requirements for use in electrical cables due to improved mechanical strength and electrical conductivity, as well as lightweight household utensils due to chitosan's antibacterial properties.
