| Abstract Scope |
Natural fiber-reinforced polymer (NFRP) composites have emerged as sustainable alternatives for structural engineering due to their low density, renewable origin, and favorable specific mechanical properties. This review examines recent developments in the structural application of NFRP composites, emphasizing material selection, structural design, manufacturing technologies, long-term durability, and mechanical performance under service conditions. Current applications in civil infrastructure, transportation, marine structures, sports equipment, and lightweight engineering are critically analyzed. Design challenges associated with environmental degradation, creep, fatigue, impact resistance, fire safety, and the absence of comprehensive design standards are discussed. Recent advances in numerical modeling, structural optimization, hybrid composite systems, and performance-based design are also reviewed. Finally, future opportunities involving sustainable construction, digital engineering, smart structural systems, and life-cycle assessment are highlighted. This review provides an engineering perspective on the transition of NFRP composites from laboratory-scale materials to reliable structural components for next-generation sustainable infrastructure. |
