Abstract: Helicopterfiber reinforced resin composite material structures are quite sensible to the internal delamination and cracks induced by impact and fatigue stress. It can make composite material structure damage catastrophically without any prewarning. Therefore, the requirement for the method that can detect delamination and cracks in the composite material structures in time is more and more imperative. And that structural health monitoring(SHM) can implement monitoring on compo-site material structures in real time and in-situ. Vibration based SHM utilizes vibration properties, such as damping, modal and natural frequency, which can be easily and continuously extract from the vibration of helicopter composite material structures. It is a SHM method which will hold application foreground greatly. The vibration based SHM technologies of helicopter composite material structures are reviewed.
