| Resumo: | Title screen In the last few years, composites have been used in various fields. Carbon fiber reinforced polymer (CFRP) is one of the composites that is widely used for a variety of purposes such as in the aerospace field, aircraft industry, medical field, automobile industry, military and many others. Non-destructive testing (NDT) with infrared thermography techniques have been broadly applied to defect detection in specimens. In the later, excitations sources from mechanical, convective, optical, or induction sources are typically employed. In this paper, the capabilities of different approaches such as conventional pulsed and Lock-in thermography, vibrothermography and LED illumination have been compared in order to detect artificial Teflon inserts between CFRP plies. For this purpose, Tanimoto criterion has been used on acquired images by different methods. A 3D finite element method (FEM) with COMSOL Multiphysics has been used in parallel to simulate and optimize the parameters of experiments. |
