Quantitative Evaluation of Pulsed Thermography, Lock-in Thermography and Vibrothermography on Foreign Object Defect (FOD) in CFRP
نویسندگان
چکیده
In this article, optical excitation thermographic techniques, including pulsed thermography and lock-in thermography, were used to detect foreign object defect (FOD) and delamination in CFRP. Then, vibrothermography as an ultrasonic excitation technique was used to detect these defects for the comparative purposes. Different image processing methods, including cold image subtraction (CIS), principal component thermography (PCT), thermographic signal reconstruction (TSR) and Fourier transform (FT), were performed. Finally, a comparison of optical excitation thermography and vibrothermography was conducted, and a thermographic probability of detection was given.

متن کاملExperimental Comparison of Lock-in and Pulsed Thermography for the Nondestructive Evaluation of Aerospace Materials
Infrared thermography is a nondestructive evaluation technique aimed to the detection of surface temperature variations related to the presence of subsurface defects. Several inspection techniques have been developed over the years with basically two approaches, lock-in thermography and pulsed thermography. These two techniques are based on the principle of heat diffusion and thermal wave refle...
متن کاملQuantitative Subsurface Defect Evaluation by Pulsed Phase Thermography : Depth Retrieval with the Phase
Pulsed Phase Thermography (PPT) is a NonDestructive Testing and Evaluation (NDT&E) technique based on the Fourier Transform that can be thought as being the link between Pulsed Thermography, for which data acquisition is fast and simple; and Lock-In thermography, for which depth retrieval is straightforward. A new depth inversion technique using the phase obtained by PPT is proposed. The techni...
متن کاملNon-destructive Evaluation of Composites Materials by Pulsed-phase Thermography: Depth Inversion
This work is focused in the application of Pulsed-Phase Thermography (PPT) to non-destructive evaluation of composite materials. In this approach, the composite sample is heated by a thermal pulse briefly and recording the surface temperature decay with an infrared camera. Data processing and depth inversion is carried out by extracting and analyzing the response of the sample on the frequency ...
متن کاملNondestructive Evaluation of Plexiglas Materials Using Lock-in and Pulse Phase Infrared Thermography
− Lock-in and pulse phase infrared thermography measurement techniques have been exploited for quantitative assessment of subsurface defects in a reference specimen made of Plexiglas. Radiometric thermal images were post-processed using a contrast approach in the frequency domain, allowing defect depth location to be resolved with a relative combined standard uncertainty of about 7% for thickne...
