Porosity Determination by Pulsed Thermography in Reflection Mode

Research output: Chapter in Book/Report/Conference proceedingsConference contribution

Abstract

In this work we measure the thermal diffusivity of a series of porous carbon fibre reinforced plastics specimens using pulsed thermography in reflection mode. These diffusivity values are compared with porosity values derived by means of computed tomography. In addition, numerical simulations of the heat transfer are performed using a finite-element program. The simulation shows that the effective thermal diffusivity values derived in reflection mode scatter more than the transmission results especially at low porosity. Furthermore, for porosities higher than 10 percent the sensitivity for both methods decreases. The experimental results are similar to those seen in the numerical study.
