In this study epoxy/vinyl ester (EP/VE) based hybrid thermoset resin was developed and used as a matrix in unidirectional carbon fabric reinforced composite. The mechanical characteristics of the hybrid and the individual resins were revealed by dynamic mechanical analysis (DMA), three-point bending, and hardness tests. The produced composites were investigated by three point bending, impact-, and fatigue tests. The morphological characterization of the materials was carried out by atomic force

Based on the results enhanced inter-laminar properties of the produced composites were exhibited. Keywords Hybrid resin · fatigue · composite · epoxy · vinyl ester · IPN 58
