IR thermography for lightning-strike damage monitoring in composite materials

International audienceThe increasing tendency to substitute metallic parts of aircrafts by lighter composite structures comes with other issues. One of them is the resistance of composite materials to lightning strike. The present paper illustrates how the use of infrared thermography can improve the understanding of lightning-strike induced damage and assess its severity. It is based on an experimental campaign carried out in ONERA: several carbon/epoxy composite samples, with or without specific protection, were impacted by lightning arcs of various current levels. An infrared camera was used during and after those tests to monitor and analyze the resulting damage inside the samples
