Damping is a significant feature of the dynamic behavior of composites to control resonant response. While some methods work effectively in forecasting the damping of laminated composites, few damping prediction approaches have been developed for woven composites. Based on the elastic-viscoelastic correspondence principle, an effective method called the complex stiffness method is presented to determine the damping properties of woven composites. The effect of damping of fiber phase in fiber tows is considered to improve the accuracy of the predictions. Experiments were performed to validate the proposed model and good agreements are achieved between test data and predictions.
