Abstract:A kind of carbon fiber-reinfored plastics(CFRP) plate, with paper and aluminium lards and air bubbles inside was fabricated. Heated by an electrical blower, the temperature change of the composite surface was recorded with an thermal imager,. The lards and air bubbles embedded in the composite can be detected and evaluated in real-time.
Keywords:infrared thermography    carbon fiber-epoxy plate    composite    defect    NDT
