Özet
The increasing demand for sustainable energy has accelerated the development of high-performance wind turbine systems. In this context, material selection for turbine blades plays a critical role in ensuring structural efficiency, fatigue resistance, and long-term reliability. This study evaluates the mechanical and structural advantages of carbon fiber reinforced polymer (CFRP) composites compared to glass fiber reinforced polymer (GFRP) materials in wind turbine blade applications. Results from the literature indicate that CFRP provides significantly higher stiffness-to-weight and strength to weight ratios, enabling up to 20-30% weight reduction in critical blade components such as spar caps. This reduction improves aeroelastic stability, decreases fatigue loading, and enhances overall energy capture efficiency. Furthermore, CFRP exhibits superior fatigue resistance under cyclic loading conditions exceeding 108 cycles, which is essential for the typical 20-30 year service life of wind turbines. However, the higher cost of CFRP remains a limiting factor, leading to its selective use in load-critical regions. The findings suggest that hybrid material strategies combining GFRP and CFRP offer an optimal balance between cost and performance.
