Highlights: Kenaf fibre biocomposites are positioned as sustainable alternatives to carbon and glass fibres for UAV applications, offering low density, renewable sourcing and significant carbon footprint reduction. The review systematically covers kenaf integration across UAV structures, electronics, and additive manufacturing, including KNFRP panels, pellets, 3D-printing filaments, pressed paper, foams and biofilms. Kenaf-based hybrid composites demonstrate enhanced mechanical, thermal and impact performance, enabling their use in semi-structural and selected load-bearing UAV components. Kenaf-based materials show strong potential for UAV electronics, providing electrical insulation, vibration damping, acoustic control, and thermal management for PCBs and sensor systems. Key challenges, such as moisture sensitivity, thermal stability, recyclability, and supply-chain scalability, are critically discussed, with mitigation strategies and future research directions outlined to enable practical UAV adoption. Unmanned aerial vehicles (UAVs) are experiencing rapid growth across diverse sectors, creating an increasing demand for lightweight, high-performance and environmentally sustainable materials. Conventional drone materials offer excellent mechanical properties but pose environmental concerns due to their high carbon footprint, energy-intensive production and limited biodegradability. Kenaf fibre, a renewable natural fibre, presents a promising alternative owing to its low density, high specific strength, cost-effectiveness and eco-friendly characteristics. This review and research proposal explores the current and potential applications of kenaf-based materials in drone manufacturing, including kenaf fibre-reinforced biocomposites, pressed paper, composite pellets and 3D printing filaments for structural, functional and electrical housing components. Kenaf-based materials have demonstrated mechanical strengths approaching 300 MPa, dielectric constants of approximately 2.5 and electrical breakdown strengths exceeding 150 kV/mm, highlighting their potential for lightweight UAV structures and electronic insulation applications. The proposed research focuses on optimising kenaf fibre treatment, fibre–matrix compatibility, hybrid reinforcement strategies and additive manufacturing parameters to develop lightweight, durable and multifunctional kenaf-based UAV components. The framework aims to establish a systematic pathway for the development and validation of kenaf-based materials for next-generation sustainable UAVs. [ABSTRACT FROM AUTHOR] |
