This study investigates the synergistic effects of incorporating heat-treated rice husk Si 3 N 4 bioceramic and corn husk fibers in high-content cellulosic corn husk fiber-polyester composites (E0 to E4). Mechanical, flammability, and fatigue properties are comprehensively analyzed. Tensile strength and modulus exhibit significant improvements, showcasing Si 3 N 4 ’s positive impact. Flexural properties demonstrate synergies between Si 3 N 4 and corn husk fibers. SEM analysis validates reinforcing mechanisms, emphasizing improved matrix adhesion and toughened matrices. Impact strength, hardness, wear resistance, and flame resistance all show positive trends, highlighting Si 3 N 4 ’s pivotal role in enhancing these properties. Tensile creep analysis indicates Si 3 N 4 ’s influence in minimizing deformation over time. Fatigue performance reflects the synergistic effects of corn husk fibers and Si 3 N 4 . Overall, these composites demonstrate enhanced mechanical strength, durability, and flame resistance, suggesting their potential for diverse applications requiring superior material properties. The study provides valuable insights into the multifaceted improvements achievable through the strategic combination of heat-treated Si 3 N 4 and natural fiber in composite materials, offering a promising avenue for advanced material development with applications in drones, automotives, aviation, and radomes.
