Infrared Thermal Wave Nondestructive Testing of Aluminum Honeycomb Composite for Bonding Defects

Since the disbond in aluminum honeycomb composite reduce the intensity of composite boards and affect their application, it is necessary to detect the defects timely. The aluminum honeycomb composite was inspected by infrared wave nondestructive testing. It was shown by experimental results that the technique was effective for rapid and intuitive testing of the bonding quality and structure of an aluminum honeycomb composite test piece.
