Aluminium with a composition of 7-10% Silicon (Si), 2-4% Copper (Cu) is a matrix used by adding Nano SiC reinforcement particles with variations of 0.25; 0.3; 0.4%Vf with the purpose of making bullet-proof materials that have high toughness, impact resistance, and good strength. In this study, fabricated composites used a stir casting process to produce superior mechanical properties which was caused by the bond between an effective matrix and reinforcement particles. Besides, the addition of Nano SiC reinforcement particles, it was also followed by adding 5%wt Magnesium (Mg) as a wetting agent, 0.04%wt Strontium (Sr) as modifier agent, and 0.15%wt Al-5Ti-1B as a grain refining agent. Fabricated composite specimens will be carried out several tests to determine mechanical properties such as density, porosity, hardness, tensile strength, impact resistance, and ballistic test. The result of the test will be compared to the results of that without the addition of reinforcement particles. Then, using the Optical Microscope (OM), Scanning Electron Microscope (SEM), Dispersive X-Ray Spectroscopy (EDX), and X-Ray Diffraction (XRD) to analyse the dispersion of reinforcement particles in the selected alloy matrix.
