Nano-sisal fiber reinforced polymer composites for biocompatible lightweight structural applications

This research focuses on the mechanical and thermal characterization of nano-sisal fiber-reinforced polymer composites, exploring the potential of incorporating nanomaterials to enhance the performance of traditional sisal fiber composites. Natural sisal fibers (NSF) serve as the starting point for the chemical and physical processes that produce sisal fibers. Several analytical techniques are used to describe the materials, such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), and field emission scanning electron microscopy (FE-SEM). This study investigates the synergistic effects of integrating nanoscale reinforcements into sisal fiber-reinforced polymer matrices. Mechanical properties, including tensile strength, flexural strength, and impact resistance, are systematically evaluated using standardized testing procedures. Fabricating epoxy polymer-based composites involves adding silver fibers in various weight percentages (1, 2, 3, 4, 5, 6, 7, and 8%). The results highlight the influence of nanoscale additives on the overall mechanical performance and thermal stability of the composite materials. Furthermore, the study investigates the potential for improved load-bearing capacity, durability, flexural strength, tensile strength, impact resistance, thermal analysis, and heat resistance in sisal fiber composite samples, where these composites could exhibit utility. The findings of this research contribute to the understanding of nano-sisal fiber-reinforced polymer composites and their viability in various engineering applications. • Nano sisal fiber composites is conducted, focusing on chemical and physical treatment. • Fourier transform infrared spectroscopy (FTIR) analysis identify the various functional group. • FE-SEM and HR-TEM characterization revealed that the mechanical and thermal properties increased for 7wt. % of nano sisal fiber reinforced composite samples due to good interfacial bonding with the fiber and matrix. • The study suggests that nano composites made bio composite could be used in medical devices like biocompatible drug delivery systems, aerospace and automotive sectors, and medical fields like blood bags and cardiac devices.
