Abstract

Delamination defects are a common cause of failure in laminated composites. Currently, laminated composites are widely used in wind turbine blades, and the laminates are made of fibrous materials laid in multiple layers, so the fiber orientation significantly affects the stress distribution of the laminates when they are subjected to forces. In this paper, the forced vibration analysis of laminates with different fiber orientation clamping angles is carried out under three different delamination defects. The von Mises stress distribution and lateral velocity of laminates were analyzed under bending and torsional loads. It is proved that the forced vibration state of laminates is the best when the fiber direction Angle is 90°.
