The Characterization of Defects in Multi-Layered Composite Materials by Thermal Tomography Methods

The idea of thermal tomography is slicing a work piece for some in-depth layers which exhibit the distribution of thermal properties in materials by the analogy with X-ray tomography. Thermal tomography is based on the analysis of the surface temperature evolution which follows thermal stimulation of test samples. In this paper, some experimental results of applying the dynamic thermal tomography algorithm to a carbon fibre reinforced plastic sample are presented. The efficiency of few data processing methods is discussed.
