The principle and the applications of infrared thermography non-destructive testing (NDT) technology
are described in this paper. Experiment results show that, the infrared thermography NDT technology is an effective
method for several adhesive products quality testing, such as, glass-fiber-reinforced-foam bonding structure, cork
bonding structure, composite honeycomb sandwich structure. It is believed that infrared thermography NDT technology
has widely application potential in future.
