Abstract: Fiber-reinforced composites have been widely used in various lightweight applications due to their excellent mechanical properties. In practice, fiber-reinforced composites are required to be connected with other heterogeneous materials such as metals, in which hybrid joints have better mechanical properties than the bonded and traditional mechanical joints. Fatigue life is the key to the service performance of fiber-reinforced composite-metal hybrid joints. This paper studies the fatigue performance of various components of hybrid joints, discusses the fatigue life prediction methods and the important factors affecting the fatigue performance of hybrid joints. Furthermore, the development trend of hybrid joints is summarized and prospected.

Key words: fiber-reinforced composites, metal, hybrid composite joint, fatigue performance, life prediction
