電気抵抗変化法と発振周波数変化を用いたCFRP積層板の無線はく離検出
For a rotating composite component such as a helicopter blade, delamination of composite laminates causes low reliability. Since it is difficult to detect the delamination of rotating component in-service with a wired system, wireless detecting system is demanded to improve the reliability. In the present study, the wireless system for detecting the delamination is proposed. This method adopts an electrical resistance change method and an oscillating circuit to transmit the information of the
