ABSTRACT: Composite materials play a significant role in modern aircraft, missiles, submarines and sports equipment due to their exceptional strength-to-weight and stiffness-to-weight ratios, as well as their superior durability, fatigue resistance and corrosion resistance. This study examined the mechanical properties, specifically the tensile, flexural, and impact strengths, of hybrid laminated polymer composites. This study focuses on how hybridization and stacking sequences affect these properties. Specifically, eight-layered composites were fabricated using plain-woven basalt (B), carbon (C), Kevlar (K), and glass (G) fibers as reinforcements with epoxy resin (LY556). The laminates, featuring symmetric stacking sequences, were produced via hot press molding at 2 MPa and 100°C. Mechanical testing was conducted using an instrumented universal testing machine to determine the tensile and flexural properties, while a Charpy impact tester was used to assess the impact resistance. The findings indicate that the stacking sequence of the layers is pivotal in influencing the tensile, flexural, and impact properties of the composite. The findings have significant practical implications in industries such as aerospace, automotive and sports equipment manufacturing, where the enhancement of material properties is crucial for optimizing both performance and safety.
