An interesting preliminary evaluation for a low-cost approach for thermographic Non-Destructive Evaluation of carbon fiber-reinforced polymer is presented. Lock-in active thermography, by halogen lamps, has been used on a CFRP specimen with several simulated defects and two different IR-Cameras were used.

Abstract

An interesting preliminary evaluation for a low-cost approach for thermographic Non-Destructive Evaluation of carbon fiber-reinforced polymer is presented. Lock-in active thermography, by halogen lamps, has been used on a CFRP specimen with several simulated defects and two different IR-Cameras were used. Both cameras have microbolometric detectors but belong to different price range (A65 and A655), with a difference of cost that changes of a factor of 3. Phase maps for three principal harmonics were analyzed and the limits of low-cost IR camera were investigated by means of a quantitative analysis in terms of the number of detected defects and normalized phase contrast (NPC), changing the acquisition frame rate.
