The use of composite materials in aerospace and other fields is more and more widespread. The structural response and fatigue characteristics of composite materials under vibration load are more concerned. In this paper, the vibration fatigue test is carried out with the typical composite structure as the research object, and two failure modes and vibration fatigue S–N curves of the typical composite structure are obtained. It can provide technical support for anti-vibration fatigue design of structure.
