Advanced NDT Techniques for DOTNAC Project: Comparative Analysis of THz Results

Explore the results of inspections conducted on calibration and blind samples using conventional and THz NDT techniques in the DOTNAC project. Discover the impact damage detection in carbon fiber and glass fiber samples, as well as the detection of inclusions such as water and Teflon. A total of 12195 data points were analyzed from 76 samples with 1742 tests performed. The workshop provides insights into the effectiveness of FMCW THz, IWEX UT, solid laminate, and other techniques in identifying defects and anomalies. Join us for in-depth discussions on this innovative NDT project's outcomes.
