Abstract
Plain GFRP laminates and stainless steel (SS) wire reinforced GFRP laminates were prepared by hand layup method. The composite specimen reinforced with SS wires placed at various pitch distances was fabricated, and drop-weight impact tests were conducted with velocities of 2.80, 3.13 and 3.43 m/s. The impact damage area was evaluated by using lighting technique, and fracture behaviors were analyzed using scanning electron microscopic images. Impact energy absorption and damage area due to low-velocity impact on the GFRP composites without wires and SS wire reinforced GFRP composites were calculated, and efficiency of absorption was compared with respect to impact velocity and pitch distance.
