Abstract
This contribution deals with the implementation of a PC-controlled structural health monitoring system for continuous damage detection. The system is implemented in a real size demonstrator component made of carbon fiber reinforced polymer (CFRP). The component is equipped with an actuator array of piezoelectric patches which are driven by power amplifiers. With the appropriate test signals elastic Lamb waves are emitted into the continuum in a specific direction. Vibrometer measurements of reflections which are caused by delaminations make it possible to observe the size and position of the defect areas.
