This work presents results from free-vibration analyses on tapered wing box made of composite material. The analyses are performed through a refined one-dimensional model based on the Carrera Unified Formulation. The displacements over the beam cross-section are evaluated using polynomial expansions. In this way, no geometrical approximations are introduced in the problem and a three-dimensional result can be obtained. Two simple tapered wing boxes have been considered and different laminations have been taking into account. The results are compared with a shell model achieved by a commercial code. The results demonstrate the good accuracy of the model and his use in tailoring analyses.
