Abstract—Hybrid composites allowed the possibility to alter the composite properties for a specific application, improving their manufacturability and reducing the cost by introducing cheaper fibres. Therefore, the hybrid of natural and synthetic fibres in a composite system has attracted interest in research field attributable to environmental consciousness. The focus of the study is to determine whether any improvement in impact response exists as a result of combining high-performance woven Kevlar synthetic fibre and woven coir natural fibre in a specified laminated stacking sequence. Thus, the study was conducted by performing an experiment to differentiate the capabilities of hybrid by comparing the impact responses effect of different stacking configurations. It focused on the impact resistance and penetration behaviour of the hybrid composites, as well as their suitability for modern structural applications. The results from this study showed that the hybrid of coir/Kevlar-epoxy laminated composites revealed an improved in impact response.
