Thermography and 3D numerical method - a tool for determination the material thermal properties

The paper presents the method for determination the thermal properties of composite material by means of active thermography and 3D numerical non-stationary heat conduction model. The method is tested on the samples made of composite materials having known subsurface defects. The results obtained are discussed from the point of view to predict the behavior of the composite material by estimation of their thermal properties. The software developed enables the calculation of the temperature distribution through the sample versus time and location of the defect by means of inverse method involving experimentally obtained thermogram.
