In this study, finite element analysis is studied to examine the dynamic behavior of composite blades with different layers and fiber orientation angle combinations. There are many factors affecting modern turbine blade performance and durability, and the most important factor is the structural features of the blade. Composite materials are an important option for turbine blades because they are lighter, more durable and more flexible than traditional metallic materials. However, examining the dynamic behavior of composite materials under different rotation speeds plays a critical role. In this context, a finite element model is created in ANSYS to evaluate the natural frequency behavior of different composite turbine blades. The finite element method is an effective approach preferred to determine the dynamic behavior of complex structures. In this way, it is determined to simulate the composite blade consisting of different layers and different fiber orientation angle combinations. The dynamic responses of different composite blade structures are evaluated and their design parameters are examined. One of the main findings of the study is the change of natural frequencies of composite blades under different dynamic rotation speeds. Higher rotational speeds generally increase the interaction between the torsional and bending modes of the wing. This can trigger resonance states of the blade structure and negatively affect the overall performance of the turbine. Therefore, it is examined how different layer combinations affect the dynamic behavior of the blade at high speeds. When the study results are evaluated, taking into account the effect of fiber orientation angles and layers of composite materials on vibration behavior can contribute to optimizing blade design parameters.
