Materials are also vital to the advancement of essential structural parts such as pressure containers, storage tanks, and an array of high- performance concepts that require a balance between high strength, long life and low mass. The objective of this research paper is to study the mechanical behavior a Kevlar/Epoxy based hybrid composite material with Al₂O₃ nanoparticles by experimental approach and analyze its compressive and tensile properties. The results show that the response of the composite was highly sensitivity to resin for compressive loading, resulting in differences in the mechanical properties. Notably, when a content (Vf) of Kevlar fibers is reduced from 55 to 50%, the composite still had sufficient tensile strength. The retention of tensile strength was due to the reinforcing mechanism of the Al₂O₃ nanoparticles that enhanced load transfer from matrix to reinforcement. A side-by-side comparison of two principal composite panels was performed and the processes undertaken in fabrication, testing, and analysis were highlighted. The investigation also demonstrates the promising perspectives of Kevlar/Epoxy-Al₂O₃ hybrid composites for lightweight, high-strength applications.
