The aim of this study is to investigate the impact and biaxial tensile-after impact behaviors of inter-ply hybrid carbon-glass/epoxy composites and reference composites. The samples prepared in five different lamination types such as 1C1G, 2C2G, 3C1G, Ref-C and Ref-G. Samples were subjected to low-velocity impact loading and then subjected to biaxial tensile testing. Some of the non-impacted samples were subjected to biaxial tensile testing for comparison with the results of the impacted samples. From the results obtained, the best impact behavior was shown by 2C2G and Ref-G samples at 17.5 J and 22.5 J energy levels while the weakest impact behavior was shown by samples with 3C1G and Ref-C lamination types for all energy levels. The highest biaxial tensile strength values were obtained in Ref-C samples while the lowest ones were obtained in Ref-G samples. For inter-ply hybrid samples, the highest biaxial tensile strength was obtained for 3C1G samples while the lowest one was determined for 1C1G samples. In addition, it was observed that the biaxial tensile strengths decreased as the energy level value increased for each lamination type. As a result, carbon-glass/epoxy hybridization has shown to have a significant/positive effect on the biaxial tensile strength of composites.
