Fiber-reinforced composites have been widely applicated in the ship fields owing to their characteristics of light weight and high strength. Although the integral forming process is becoming mature， the assembly and joint of the composites is still a challenge. Therefore， improving the mechanical properties of joint is the key to the application of fiber-reinforced composites. This paper introduces the normal joining technology， including mechanical ， adhesive and hybrid joints， which also briefly describes the key points during designing the joint. Finally， the future application of joining technology for fiber-reinforced composites in the ship fields is summarized and prospected.
