Thermal imaging of composite panel 1 (a), panel 6 (b), and panel 7 (c) under microwave exposure. Panel 1 is a 10 cm × 10 cm composite but appears oblong due to orientation of thermal camera. Panels 6 and 7 are 5 cm × 5 cm composites that were masked along the edges with microwave nonabsorbing tape to prevent arching along edges. It is clear that introduction of CNTs allows for better heating efficiency as the entire panel can be heated to the required temperature for healing.
