Advanced sustainable bio-composites: Integrating continuous fiber reinforcement with biomimetic design for high-performance applications

The growing need for eco-friendly materials has driven efforts to create new bio-composites that reduce reliance on non-renewable resources and minimize environmental damage. However, bio-composites often need more strength and durability than traditional petroleum-based materials, making them unsuitable for demanding engineering applications. This study addresses these challenges by adding continuous fibers to a bio-based matrix, significantly improving the material’s strength, stiffness, and lifespan. The enhanced composites reached a maximum tensile strength of 120 MPa, averaging 105 MPa, while their flexural strength averaged 90 MPa. Continuous fibers provide the structural support needed to handle heavy loads and resist bending under stress. Additionally, this research uses biomimetic design—drawing inspiration from natural structures—to optimize the composite’s internal structure. By mimicking how natural materials are organized at the microscopic level, the composites achieve a better balance of density, toughness, and stiffness, along with improved resistance to damage. The findings show that combining continuous fibers with biomimetic design in GO/AG nanocomposites creates high-performing, eco-friendly materials without relying on synthetic polymers. These advancements pave the way for sustainable materials suitable for automotive, aerospace, and construction industries.
