Abstract
The goal of this study is the analysis of some candidate defect characterization parameters in application to the detection of impact damage in carbon fiber reinforced polymers. It is shown that quantitative evaluation of 'defectivity' aimed to further estimation of material strength, or lifetime, should be done by determining material thermal properties. Experimental results obtained are related to active thermal nondestructive testing of aviation panels with impact damage. The efficiency of some image processing algorithms, such as principal component analysis, Fourier and wavelet transform, has been evaluated. It has been found that the result of image sequence processing should be an image of diffusivity in a two-sided procedure and image of effusivity in a one-sided procedure.
