Jute fiber, an abundantly available natural fiber, is increasingly explored for structural composite applications. However, its inherent flaws and the limited development of optimized textile architectures have restricted its use in high load-bearing engineering applications. Hybridization with glass fiber offers a promising route to enhance the mechanical performance of jute composites while reducing the reliance on synthetic materials. Nonetheless, challenges remain in achieving high jute content and sufficient strength within hybrid structures. To address these limitations, this study presents the development of a novel hybrid preform architecture using a fiber wrapping technique, where glass fibers serve as the core and jute fibers are wrapped around them. Additionally, graphene oxide (GO) treatment was applied to modify jute fibers, improving their compatibility with glass fibers. Mechanical testing revealed that the GO-treated hybrid composite (G.cGFJF) demonstrated the highest performance, achieving a tensile strength of 272.63 MPa, a flexural modulus of 10.42 GPa, and an impact resistance of 85.56 kJ m. Moreover, water absorption was significantly reduced to 1.12% in GO-coated samples, attributed to enhanced surface hydrophobicity and interfacial bonding. These results highlight the strong synergistic effects between the high-strength glass fiber core and the interlocking jute fiber wrap, indicating that GO-modified jute/glass hybrid composites hold great promise for next-generation structural components in automotive, aerospace, and civil engineering sectors where performance and sustainability are critical.
黄麻纤维是一种储量丰富的天然纤维，在结构复合材料应用方面正得到越来越多的探索。然而，其固有的缺陷以及优化纺织结构的有限发展限制了它在高承载工程应用中的使用。与玻璃纤维进行混杂提供了一条有望提高黄麻复合材料机械性能同时减少对合成材料依赖的途径。尽管如此，在混杂结构中实现高黄麻含量和足够强度方面仍然存在挑战。为解决这些限制，本研究提出了一种采用纤维缠绕技术的新型混杂预制件结构的开发方法，其中玻璃纤维作为核心，黄麻纤维缠绕在其周围。此外，应用氧化石墨烯（GO）处理来改性黄麻纤维，提高它们与玻璃纤维的相容性。力学测试表明，经GO处理的混杂复合材料（G.cGFJF）表现出最高性能，实现了272.63 MPa的拉伸强度、10.42 GPa的弯曲模量以及85.56 kJ m的抗冲击性。此外，GO涂层样品的吸水率显著降低至1.12%，这归因于表面疏水性和界面粘结的增强。这些结果突出了高强度玻璃纤维核心与相互缠绕的黄麻纤维之间的强大协同效应，表明GO改性的黄麻/玻璃混杂复合材料在汽车、航空航天和土木工程领域对下一代结构部件具有巨大潜力，在这些领域性能和可持续性至关重要。
