N2 - The object of this paper is to numerically investigate the fluid-structure interaction of composite hydrofoil. The aim is to validate 3D numerical simulation model with fluid-structure interaction of composite materials comparing to experimental data, and study the fluid-structure interaction of composite hydrofoil. Numerical results are presented for a composite hydrofoil. The hydrofoil has unswept trapezoidal planform of aspect ratio 3.33. The numerical model has been validated and showed reasonable agreement with the experiment measurements. Then the forces and deformations of composite hydrofoil with different plying angles have been investigated at Re=1x106 and initial angle of attack α=6°. The results show that lift and drag coefficients and tip twist angle decrease and get minimum at about plying angle θ=35°. According to Classical Laminate Theory, the intrinsic bending-twisting coupling of composite structures leads to the variation of twist angle for different plying angles. The relation expression on elements of matrices D has been derived to estimate twist angle at tip qualitatively.
