Feasibility study on the use of date palm fibers in 3D printing : application to small wind turbine blades

Abstract

This project explores the development of biodegradable composite materials for 3D-printed small-scale wind turbine blades, emphasizing sustainability and mechanical performance. A composite of polylactic acid (PLA) reinforced with palm leaf fibers is designed, fabricated using a hydraulic press, and mechanically characterized through tensile testing and filament extrusion trials. A detailed literature review supports material selection and processing. The obtained properties are used in aeroelastic and aerodynamic simulations via QBlade, covering airfoil analysis, blade geometry, and structural deformation. The PLA–palm composite is compared with conventional materials like CFRP and GFRP. Results demonstrate promising performance, suggesting this bio-composite as a viable, eco-friendly alternative for wind energy applications.
