Paper Details

This study investigates the mechanical properties of short natural fiber-reinforced thermoplastic composites (NFCs), emphasizing their potential for enhancing performance while supporting sustainability. By analyzing fibers such as flax, hemp, kenaf, sisal, and abaca, we reveal how their distinct chemical compositions and physical traits impact the mechanical characteristics of NFCs. Key factors including fiber content, length, diameter, and orientation are examined to identify optimal conditions for maximizing strength and stiffness. Our findings underscore the critical role of fiber-matrix interfacial bonding in effective stress transfer, while highlighting techniques like chemical treatments to improve wettability and overcome challenges posed by the inherent differences between natural fibers and polymer matrices. The study also addresses the complexities of fiber dispersion and orientation in composite manufacturing. Despite certain challenges, including moisture absorption and variability in fiber quality, NFCs demonstrate considerable promise in applications across automotive, aerospace, and marine industries, offering lightweight and cost-effective alternatives to traditional materials. This research lays the groundwork for future innovations in sustainable material development, pointing to enhanced performance through refined processing techniques and material selection.
