Physicomechanical Properties of Al6063 Metal Matrix Composite Reinforceed with Incinerated Waste Cardboard Paper Ash

Aluminium matrix composite has been a subject of consideration and research by numerous researchers due to the expanding need for improved AMCs in the production and engineering field. However, due to their low strength, conventional aluminium cannot satisfy the demand of the modern industry. Hence, particulate reinforcement is required to enhance its physical and mechanical properties. This study analyzed the physicomechanical properties of A16063 reinforced with different weight fraction (2%, 4%, and 6%) of incinerated waste cardboard paper ash via the stir casting method. Properties such as density, percentage porosity, hardness and tensile test were compared to the unreinforced Al 6063. Results showed that the percentage porosity, hardness and tensile strength of the reinforced composites increased as the weight fractions of the reinforcement increased, while the density of the composites reduced as compared to the unreinforced matrix. The physicomechanical properties of the A16063 reinforced with incinerated waste cardboard paper ash reinforced Al 6063 suggested that they are suitable for utilization in lightweight engineering application.
