Many researchers are searching for structural materials of high strength, less weight and low cost. In generally strong materials are relatively density and light materials have less strength. In order to achieve high strength and less weight, we go for composite materials. Then the tensile strength and impact strength of specimens is determined using ultimate testing machine and impact testing machine. This study investigates the mechanical properties of composite materials by incorporating various fibers, namely S-Glass, Aramid and Nylon, each combined with a 10% addition of carbon powder. Additionally, hybrid combinations of these fibers such as S-Glass + Aramid + 10% Carbon Powder, Aramid + Nylon + 10% Carbon Powder, Nylon + S-Glass + 10% Carbon Powder and Nylon + S-Glass + Aramid + 10% Carbon Powder are explored. Polyester-resin is utilized as the matrix material to form the composite specimens, adhering to ASTM standards. The research focuses on evaluating the mechanical performance of the composite materials through comprehensive testing methods. Tensile Strength, Flexural Strength, Impact Strength, and Hardness are examined to assess the material's overall robustness. Scanning Electron Microscopy (SEM) is employed to study the microstructure of the composites, providing insights into the distribution and interaction of the fibers within the matrix. Furthermore, the study extends to practical applications by analyzing car bumper made from the composite materials. A static analysis is conducted to determine Von-Misses stress, total deformation. This analysis aids in understanding how these materials perform under real-world conditions, specifically in scenarios relevant to automotive applications. The outcomes of this research contribute valuable insights into the potential enhancements in mechanical properties achieved by incorporating different fibers and carbon powder in composite materials. The findings offer guidance for optimizing the composition of hybrid fiber-reinforced polymers for applications demanding high strength and impact resistance, such as automotive components.
