WTB4: MODAL ANALYSIS OF WIND TURBINE BLADES BEHAVIOR WITH FOUR DISTINCT MATERIALS

To stay up with the constantly changing energy sector, wind turbine lifespan and energy efficiency must be increased. The advantages of the composite-material blade include low weight, high tensile strength, anti-corrosion, fatigue resistance, and thermal insulation. The selection of materials for wind turbine blades has been the subject of extensive research, particularly the comparison of metals and composites. Because of their characteristics, composites clearly produce better results than metals. However, there remains a research gap in determining which of the several composites is the best material. To examines the natural frequencies and associated deformation of four wind turbine blades composed of Kevlar, aluminium composites, Carbon Fibre Reinforced Plastic (CFRP), and Glass Fibre Reinforced Plastic (GFRP) this research work proposes WTB4: Modal Analysis of Wind Turbine Blades Behavior with Four Distinct Materials. This research goal also includes confirming the blade's strength and evaluating the aforementioned materials to determine which is most appropriate for a wind turbine blade and their vibration patterns. From the results, it is observed that the Carbon fibres provide stronger stiffness, lower compressive strength and a greater sensitivity to misalignment compared to other composite materials
