Abstract
This work focuses on investigating the effects of thermal cycles in the impedance-based damage detection performance of Macro-Fiber Composites (MFC). A host structure with an MFC bonded to its surface is submitted to a 90 minutes temperature cycle that varies from -20°C to 65° C. After each cycle the electrical impedance of the test sample is measured with and without the presence of a representative damage (an added mass). The results indicate that the thermal cycling affects the smart device by changing its impedance profile, a phenomenon that should be taken into account in damage detection algorithms.
