Hybrid reinforced composites present a wide range of mechanical properties that it cannot be obtained with an only type of reinforcement. Thus, that kind of materials has recently aroused great interest for industrial applications. Particularly, Kevlar-carbon plies are strongly appreciated in nautical applications where resin degradation plays a critical role. In this work, different hybrid Kevlar-carbon vinyl ester resin laminates were carried out varying the sequence and the orientation Kevlar-carbon plies. With these plies and by using different cure conditions, composites were obtained what allowed us to optimize thermic and mechanical properties of the parts obtained. Maximum values of the mechanical properties were obtained for all types of laminates after a cured cycle at room temperatures and post-cured treatment at 100C during 3 hours room temperature. Likewise, it has been proved that the conFiguration of the laminates according to different orders of the involved layers influences greatly those properties. Source
