Fiber reinforced resin matrix composites are increasingly used in various fields and they are the key strategic materials related to national defense security and economic development. The vibration of composites can lead to undesirable effects in practical applications. It is of great significance to study its vibration mechanism and optimize its vibration performance to improve the application of composites. In this paper, the basic principles of vibration analysis of composites are firstly introduced. Then, several mathematical analysis methods for obtaining the natural frequencies and forced responses of composites are discussed. Furthermore, various structural and material parameters influencing natural frequencies are analyzed. In addition, the research methods on the vibration of variable stiffness composites are reviewed. Finally, some future research directions on the vibration performance of composites are also discussed.
