This study investigates the structural and dynamic properties of a three-meter H-rotor Darrieus Vertical Axis Wind Turbine (VAWT) blade using a detailed 2D finite element method analysis. We conducted both static and dynamic analyses on a cylindrical cross-section of the VAWT blade, examining different composite configurations: a three-layer, a five-layer, and an eleven-layer configurations. The results indicate that the five-layer composite structure offers optimal performance, balancing strength and manufacturability. The three-layer configuration exhibited significantly higher in-plane normal stresses, up to 139.22% more, and 29.02% higher transverse shear stresses compared to the five-layer configuration, indicating increased structural vulnerability. In contrast, the five-layer and eleven-layer composites showed minimal differences, with only a 0.55% increase in deflection for the five-layer composite. The five-layer configuration demonstrated comparable mechanical properties to the eleven-layer composite while being more cost-effective and easier to manufacture. These findings underscore the potential of optimizing composites to enhance the durability and efficiency of VAWTs, particularly in offshore and airborne applications where weight and cost are critical factors. This research contributes to the optimization of VAWT designs, paving the way for more sustainable wind energy solutions.
