Abstract

The use of new materials and new production techniques enables the industrial production of the ever more complex parts. This increases the requirements to the non-destructive testing methods. Previous studies have shown that pulse-phase thermography (PPT) is a fast and effective method to detect flaws in Carbon Fiber Reinforced Plastic (CFRP) parts. Currently PPT is mostly used for qualitative analysis. This study shows a possibility to estimate material parameters from PPT data. To avoid distortions which may occur by the use of DFT, a new method to transform recorded data from the time domain into the frequency domain will be elucidated in this study. Material parameter can be estimated by fitting the phase curve of the analytical solution of the heat conduction equation to the phase curve of recorded data. The capability of this material parameter estimation procedure was tested on finite element simulations and on experimental data.
