@article{(Open Science Index):https://publications.waset.org/pdf/16125, title = {Development of an Infrared Thermography Method with CO2 Laser Excitation, Applied to Defect Detection in CFRP}, author = { Sam-Ang Keo and Franck Brachelet and Florin Breaban and Didier Defer}, country = {}, institution = {}, abstract = {This paper presents a NDT by infrared thermography with excitation CO2 Laser, wavelength of 10.6 μm. This excitation is the controllable heating beam, confirmed by a preliminary test on a wooden plate 1.2 m x 0.9 m x 1 cm. As the first practice, this method is applied to detecting the defect in CFRP heated by the Laser 300 W during 40 s. Two samples 40 cm x 40 cm x 4.5 cm are prepared, one with defect, another one without defect. The laser beam passes through the lens of a deviation device, and heats the samples placed at a determinate position and area. As a result, the absence of adhesive can be detected. This method displays prominently its application as NDT with the composite materials. This work gives a good perspective to characterize the laser beam, which is very useful for the next detection campaigns. }, journal = {International Journal of Civil and Environmental Engineering}, volume = {7}, number = {8}, year = {2013}, pages = {580 - 584}, ee = {https://publications.waset.org/pdf/16125}, url = {https://publications.waset.org/vol/80}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 80, 2013}, }
