Resumo: In this study, three modalities of Thermography (Pulsed, Pulsed Phase and Lockin) were used to detect delamination defects in CFRP samples from the 4ENF test. The results obtained for each modality were compared in relation to the real delamination area in these samples. In addition to the experimental analysis, a computational simulation model was also created to evaluate the influence of defect parameters (depth and thickness) on its thermal contrast and thus estimate the detection limit presented by the Pulsed modality.
