In this study, the natural responses of fiber reinforced composite hydrofoils are obtained using FEM. It is of great importance to estimate the vibrational responses of fiber reinforced composite hydrofoils correctly due to the flexible characteristics of the material. Modal analysis is performed on a cantilevered hydrofoil which has a cross-section of a modified NACA0009 profile using FEM software Abaqus 2019. Newly developed structured mesh modeling method is used, and the results are compared with the conventional modeling methods and experiment. In the developed mesh model, boundaries of the layers are modified in order to apply a structured mesh. By investigating the stress distribution of the hydrofoil for the bending mode case, it is evident that the developed mesh model results in the most accurate and physical result compared to existing modeling method.
