Fabrication and Property Investigation of Silicon Carbide Reinforced Aluminium-based Metal Matrix Composite for Aerospace Materials
The modern development in the field of science and technology has created a demand for many advanced engineering materials. In recent days, Aluminiumrelated metal matrix composite is a probable material for many applications such as transport, aerospace, marine, and automobile applications. The stir casting method is generally used in the production of Silicon carbide reinforced Aluminium metal matrix composite to enhance the properties of base metal. The objectives of the study were fabrication and characterizations of physical and mechanical properties of Silicon carbide reinforced Aluminiumbased metal matrix composite for aerospace materials. Different weight fractions of Silicon carbide, (Silicon carbide: 5 weights%, 7 weights%, and 9 weights%) particulate-reinforced Aluminium metal matrix composites are fabricated using the stir casting method, and characterizations of the physical and mechanical properties of the materials are performed based on the experiments. Characterization studies were conducted on the Aluminium 5083 and composite samples to assess. The hardness properties were evaluated using the Rockwell hardness machine. The computer interfaced INSTRON Universal Testing Machine was used to evaluate tensile strength. At all diameters of the ball indicator, hardness was increased with the increase of% value of Silicon carbide. Also, higher than those of standard Aluminium used in aerospace materials. Ultimate tensile strengths for 5 weights%, 7 weight%, and 9 weight% particulate-reinforced Aluminium metal matrix composites had 275 MPa, 287.77 MPa, and 296.96 MPa, respectively. Young’s modulus of elasticity was highest for specimen 3 (Silicon carbide 9% and Aluminium-5083 91%). Tensile strength and hardness of Aluminium metal matrix composites are enhanced by the increment of the weight fraction of the reinforcing phase (Silicon carbide).
