Analysing the Effect of Composite Ply Counts & their Orientation on the Vibration Frequency of a Wind Turbine Blade

Wind turbine blades are subjected to various loading conditions, including extreme weather. Modern wind turbine blades are typically made from composite materials, making it essential to map the structure of these composites to their mechanical properties. This study examines the vibration frequency response of a wind turbine blade as a function of ply count and fiber orientation in the composite material. The findings indicate that as the number of plies in the composite increases, the influence of fiber orientation decreases. However, a higher ply count also results in increased vibration frequencies, which may not be desirable for practical applications. This research aims to identify an optimized set of material parameters that can be mapped to achieve specific desired properties.
