The invention of novel materials is essential for present-day industry and society. These sectors are looking for not only strength and cost but also on environmental compliance issues. Synthetic fiber-reinforced composites (SFRC) are having enough strength but are not biodegradable and not environmentally friendly. Natural fiber reinforced composites (NFRC) have moderate strength but are environmentally friendly and biodegradable. The drawbacks in NFRC and SFRC composites were addressed by the hybridization of composite. The current research aims to investigate the performance of a hybrid composite plate made of coconut coir (CC), carbon-fiber (CF), and epoxy resin. The hand layup method was followed to fabricate the hybrid composite. Five samples were prepared, based on varying weight percentages in the following stacking order of 20CC, 15CC/5CF, 10CC/10CF, 5CC/15CF, and 20CF. Utilizing the universal testing machine (UTM – INSTRON 3369) and the Izod impact tester, the tensile, flexural, and impact strengths were determined. In contrast to other composites, the hybrid 10CC/10CF composite has high mechanical properties. The SEM (Scanning electron microscope) analysis revealed bonding between the CC, CF, and epoxy. The developed hybrid composite is useful in industries such as footwear, textiles, marine, military, and aerospace.
