Research Abstract

In the present research, a real-time and non-contact identification method of the location and the history of the impact force acting on the aerospace CFRP structures is developed using radiated sounds occurring at the impact. The real-time method to estimate the occurrence and the extent of the impact damage in the CFRP structures is also developed from the identified force history. That is, the location and the force history are identified from the radiated sounds measured with microphones, and the monitoring method to estimate the impact damage is also developed. The validity of the present method is verified through the application to CFRP laminated plates and CFRP sandwich panels.
