The use of carbon-fiber-reinforced plastic (CFRP) in aircraft and space structures is recently increasing. We investigated the possibility of nondestructively detecting a delamination in CFRP using a low-Tc first-order gradiometric superconducting quantum interference device (SQUID) loop. A CFRP plate including a thin insulator sheet between the central layers was prepared. The injected current method was adopted. The magnetic field due to the sheet was measured by a SQUID nondestructive evaluation system using the lock-in detection technique. The position and size of the sheet were successfully detected by mapping the measured field. The result agreed with that by ultrasonic testing. Future application of this method for detecting deep-lying flaws was discussed.
