Structural health monitoring (SHM) based on Lamb waves, a type of ultrasonic guided waves, is a promising method for in-service inspection of composite structures. Lamb waves can be excited and received using a network of actuators and sensors, which are permanently attached to the structure. By analysing the sensor signals, different kinds of structural defects can be detected and located through the interaction of the Lamb waves. This paper presents the development and manufacturing of a full-scale composite fuselage panel with a door surround structure and integrated SHM system. The SHM system consists of piezoceramic sensor arrays, which are integrated into the composite manufacturing process in the form of semi-finished parts. With this approach, the manufacturing steps and costs can be reduced. |
