There has been an increasing Interest in composites containing low density and low cost reinforcements. Among various discontinuous dispersions used, fly ash in one of the most inexpensive and low density reinforcement available in large quantities as solid waste by product during combustion of coal in thermal power plant. The study conducted investigates the impact of incorporating varying proportions (ranging from 0% to 9%) of silicon carbide (SiC) and fly ash (FA) into AA7075 aluminum alloy composites. These composites were fabricated using the stir casting method, a widely used technique in composite material synthesis. Notably, the study employed equal proportions of SiC and FA in the composite fabrication process, ensuring a balanced distribution of both reinforcements. The mechanical properties of the prepared composites were extensively evaluated. Specifically, three key mechanical properties were examined: Young's modulus, impact strength, and flexural strength. Young's modulus indicates the stiffness of a material, impact strength measures its ability to withstand sudden loads or shocks, and flexural strength gauges its resistance to bending. This research provides valuable insights into the optimization of composite materials through the incorporation of SiC and FA, thereby paving the way for the development of high-performance materials with enhanced mechanical properties, suitable for a wide range of engineering applications.
