NDT Study of Complex CFRP/GFRP Structure by Means of Active Thermography
Method. The calibration plate with Teflon inserts as artificial defects was tested. The standard configuration of the NDTherm® NT system was used together with the specially developed algorithm for enhancing the contrast via special time compression and polynomial fit to ensure noise reduction.
Results. The Teflon inserts were clearly seen under 16 layers of hybrid structure. It took less than 5 minutes to run measurements.
Conclusion. The results have shown that this noncontact method is quick, reliable and cost-effective. The Opgal NDTherm® Technology and product line has shown enhanced detection capabilities in various applications.
