The study examines the structural performance of nine lightweight composite materials under shock and impact loads using both experimental and computational methods. The top three lightweight materials are identified for further analysis. The study also investigates composite materials' behavior under rapid loading in real-time applications like bullet crash analysis, UAV propellers, and car bumpers.The crash analysis of three composites - CFRP, GFRP, and KFRP - is performed using ANSYS Workbench's explicit technique-based finite element analysis (FEA). Comparisons are made based on structural characteristics, and two grid convergence tests validate computational processes and discretization accuracy. Standard methodologies are applied across all three real-time applications, ensuring acceptable error percentages.
