    Abstract

    In this study, the composites with different reinforcement structures, namely three-dimension and five-direction braided, three-dimension and four-direction braided, and laminated structures, are designed and the effects of different reinforcement structures on the vibration properties of the corresponding composites were analyzed. The dynamic properties of the braided composites and laminated composites were compared. Multivariate analysis of variance demonstrated that the structure of the reinforcement had a significant effect on the natural frequency and damping ratio of the composites. The composites with advanced braided structure had the good dynamic mechanics behavior, such as relatively high natural frequency, damping ratio, and the ratio of stiffness to weight, as well as fairly good stabilization. This study provides the basis for composite design and the selection of reinforcement structures under different conditions.
