The observed trend in Figure illustrates that tensile modulus of the composites exhibits a rise with the augmentation of the coupling agent content. The enhancement in stiffness of the composites can be attributed to the presence of the coupling agent. The introduction of a coupling agent to change the fibers can lead to an improvement in the tensile strength and tensile modulus of EFB/kenaf hybrid green composites. The aforementioned attribute makes composites a more suitable choice for applications that require heightened degrees of strength and stiffness. .
