Active Microwave Thermographic Measurement of In-Plane Thermal Diffusivity
Abstract
This research shows the efficacy of an Active Microwave Thermography (AMT) based thermal materials characterization approach for measuring in-plane thermal diffusivity. To this end, two independent approaches, space-resolved and iterative, are utilized to extract the in-plane thermal diffusivity from AMT measurements conducted on two quasi-isotropic CFRP laminates. The experimental results obtained from the two approaches yield consistent values of the in-plane thermal diffusivity, thus supporting the validity of the results and showing the applicability of the AMT-based materials characterization technique.
