Randomized trial assesses fatigue life in small wind turbine blades, indicating potential for cost-effective design.

This study aims to analyze the structural performance and fatigue life of small wind turbine blades made from various composite materials.
Conducted finite element structural analysis using ANSYS Mechanical 2024 R2.
Evaluated three composite laminate configurations: GFRP, CFRP, and a hybrid design.
Performed modal analysis to assess natural frequencies and resonance avoidance.
GFRP laminate achieved a fatigue life of 2.84 × 10⁸ cycles, meeting design requirements for 20 years.
CFRP provided 35.5% lower mass and 18.9% enhanced fatigue life compared to GFRP but was 8.4 times more expensive.
Hybrid CFRP/GFRP reduced mass by 21.1% while maintaining a cost of 3.2 times that of pure GFRP.
