Present study addresses the influence of stacking sequence effect on damage tolerance and impact behavior of hybrid composite laminates. Hybrid composite samples were fabricated with two and three different fiber combinations of woven carbon, Kevlar, and glass fibers. The behavior of impact resistance was measured by using as instrumented drop weight impact machine. The resulting failure and damage tolerances were compared with observing the impacted and nonimpacted surfaces. The degree of the hybridization effects was evaluated with reference to rule of mixture in terms of absorbed energy. The results from this study showed that the position of fibers in the hybrid samples was a major factor regarding to damage mechanism and impact resistance. Due to the asymmetric structure of the hybrid samples, the side of their impacted surfaces was significantly affected the load and deflection characteristics during the impact event. POLYM.
