Abstract: In recent years, Glass Fiber-reinforced plastic (GFRP) composite materials have been increasingly replacing conventional metallic materials in structural applications, due their excellent specific strength and stiffness properties. However, GFRP laminate having weak interfaces in normal to loading direction and they are very susceptible to impact loading. The damage of composite structures to impact events is one of the most important aspects of study to uncover the significance and the more dominant damage characteristics in terms of impactor mass, impact velocity, impact energy and different stacking orientations. This paper presents the effect of stacking sequence on low velocity impact behavior of GFRP composite laminate.

Keywords: Glass Fiber-reinforced plastic, stacking sequence, Specific Strength, impact velocity
