Abstract
The study attempted to identify optimal material and the overall enhancement and longevity of wind turbine blades. The research approach adopted for this study is a combination of a comprehensive literature review and a rigorous computational analysis using Finite Element Analysis (FEA).Finite Element Analysis (FEA) is a computer-aided engineering (CAE) tool employed to simulate the physical behavior of structures and materials. This tool allows for detailed analysis under a multitude of conditions, including various types of loading and environmental stresses. The first step in the FEA-based structural analysis is to develop a model of the wind turbine blade. Structural loads on wind turbine blades primarily consist of gravitational, aerodynamic, and centrifugal forces. Environmental conditions play a pivotal role in the performance and durability of wind turbine blades. The analysis procedure will be an iterative process that employs Finite Element Analysis (FEA) methods for structural evaluation. The use of FEA is considered a reliable approach in compliance with the BS EN 61400 UK standard for wind turbine blade design. The chosen approach, involving Finite Element Analysis (FEA), is justified due to its proven effectiveness in predicting the structural response of complex structures such as wind turbine blades under varying loading conditions. While the Finite Element Analysis (FEA) approach is a powerful tool for modeling and analyzing the structural behavior of wind turbine blades, it comes with some limitations.To minimize these limitation, the model will be validated against experimental data, and a sensitivity analysis will be performed to assess the impact of the different parameters on the results. This composite material has gained significant traction due to its impressive mechanical properties, notably its high strength-to-weight ratio and corrosion resistance. In the context of wind turbine blades, CFRP offers a compelling value proposition. Its lightweight nature reduces the structural burden on the entire turbine system, thereby improving overall efficiency. Additionally, its resistance to fatigue ensures longevity, a key sustainability factor. The longer a blade remains in service, the fewer resources are expended in its replacement. One of the recommendations made was that a holistic approach should be adapted to sustainability, encompassing material selection, production, usage, recycling, and disposal. Embrace recycling, repurposing, and eco-friendly disposal practices to minimize waste and environmental impact.
