Natural-Fibre-Reinforced Composite-Based Micro-Size Wind Turbines: Numerical Analysis and Feasibility Study

Due to their inherent advantages, micro-sized horizontal axis wind turbines (HAWT) are preferred over vertical (VAWT) for urban applications. Typically, HAWTs on the market constructed using steel, alloys, or fibre-reinforced composites, with latter being most economical and stable in comparison steel alloy-based HAWTs. Nevertheless, light of increased emphasis cost savings environmental sustainability, natural-fibre composites have become more desirable. This study focuses implementation flax-fibre-reinforced HAWT blades designed applications particular. The proposed were CATIA feasibility performance evaluated via numerical analyses ANSYS. Structural, modal, harmonic conducted under various loading conditions. results indicate that possess higher natural frequencies, greater stability, lower deflection amplitudes at resonance frequencies than other materials.
