Objectives To develop a patch repair system that will allow rapid repair and turn-around of aircraft under field conditions. To develop a monitoring system embedded into the patch that, which detects and monitor the cure condition. To develop a system that can act as strain gauges to monitor residual stress due to the cure process. To develop a system that can both transmit and receive Lamb waves in order to detect voids, debonds and crack propagation in the substrate. To integrate all above into one system.
