Natural fiber-reinforced polymer (NFRP) composites rely on a complex interplay between the reinforcing fibers and the surrounding polymer matrix. The fibers, derived from renewable resources like plants, provide tensile strength and stiffness, while the matrix binds the fibers together and distributes loads. However, the performance of these composites is significantly influenced by fiber properties such as length, orientation, and surface treatment. For instance, studies demonstrate that increasing fiber length generally enhances mechanical properties, while certain chemical treatments can improve fiber-matrix adhesion, further boosting performance.
