Abstract:
Fiber-reinforced polymer (FRP) composites are widely used in engineering applications due to their high strength-to-weight ratio and excellent mechanical performance. Hybrid composites, combining carbon and glass fibers, offer the ability to tailor stiffness, toughness, and energy absorption for specific requirements. This study investigates the impact resistance behavior of hybrid Glass-Carbon (0/90)?s composites fabricated using the Vacuum Assisted Resin Transfer Molding (VARTM) process. Two stacking sequences were examined: Group A, with carbon fibers on the outer surfaces, and Group B, with glass fibers externally. Drop-weight impact tests were performed at three energy levels (15 J, 30 J, and 60 J) according to ASTM D7136/D7136M. The results revealed that Group A exhibited higher peak load values, indicating superior stiffness and penetration resistance, while Group B showed greater deflection and enhanced energy absorption due to the ductile nature of the glass outer layers. These findings demonstrate that fiber hybridization and stacking sequence significantly influence impact response, enabling engineers to optimize composite configurations for either stiffness or toughness in structural applications.
