Fiber-reinforced composites have widespread applications in fields such as aerospace, automotive and even in the consumer domain, due to the fact that they exhibit high strength-to-weight ratio, enhanced stiffness and good corrosion resistance. Among the available synthetic materials, E-glass has been widely used mainly due to its ease of availability and better design flexibility. In this study, GFRP/epoxy composite laminates were fabricated using a vacuum bagging process, with varying thickness and in turn subjected to low velocity impact under constant impact energy of 15 J. The laminate behavior was investigated based on peak force, energy absorption, displacement and damage area. Further, based on the test results it was found that the damage area of the laminate, maximum displacement and contact duration of the impactor decreased while, the peak force increased by 2.39 times from 6 layers to 18 layers. The failure mode areas are presented for different thickness of laminate and it was found that fiber failure was noted in thin laminates and delamination was detected in thick laminates.
