Abstract
Low-velocity impact tests were performed to investigate the impact behaviour of hybrid composite laminates reinforced by basalt-nylon intraply fabrics. The purpose of using this hybrid composite is to combine the good mechanical property of basalt fiber as brittle fiber with the excellent impact resistance of nylon fiber as ductile fiber. Five different types of woven fabric with different content of nylon (0%, 25%, 33.3%, 50% and 100%) were used as reinforcement. For hybrid fabrics the percentage of nylon is equal in the warp and weft direction. The quasi-isotropic stacking sequence was selected for this study. The height of 2.4 m was chosen, corresponding to nominal impact energy of 30 J. The c-scan techniques were employed to assess the internal damage of composite laminates. The results show that impact performance of these composites was affected sufficiently of the basalt/nylon fibers content. The visual inspection and ultrasonic c-scan of the impact damaged specimens revealed that content of basalt/nylon fiber could restraint the type and size of damages.
Keywords: Intraply hybrid, Basalt, Nylon, Low velocity Impact, C-scan.
