AbstractAbstract With the progress in science and technology, the use of polymer composites has become increasingly widespread for both scientific research and engineering applications. Especially, glass and carbon fiber/epoxy composites are increasingly demanding for structural applications in aerospace, automotive and marine industries due to their excellent mechanical performance and design advantages over conventional materials [1]. At the same time, the dynamic behavior of composites under impact loading is one of the major concerns in the use of the industry as it is highly susceptible to impact loads which cause significant damage such as cracking of the matrix, delamination and breakage of the fibers [2]. Although carbon fiber reinforced composite laminates have excellent tensile properties, they are vulnerable to out-of-plane applied loads and compressive stresses that occur in low speed impacts [3]. Glass fibers, light and cheaper materials, are generally more ductile, although tensile strengths are slightly lower than carbon fiber [4]. Hybridization, which is applied to composite structures as a "synergistic strengthening" by combining advantageous features of two different reinforcing elements, is widely used where high structural performance and economic efficiency are required [5].
