Evaluation of selected thermal properties of components of bonded joint for purposes of active thermography

Adhesively bonded joints are widely used in the automotive industry. Different kinds of defects could appear in the bounded joint during its creation. The defects could be detected by use of many destructive and non-destructive methods including active thermography. Application of active thermography requires setting of test parameters. It could be done based on analytical or numerical models which requires material properties of bonded components. In the article presented results of measurements of thermal diffusivity and specific heat of automotive steel and adhesive for purposes of further modelling and estimation of active thermography test parameters.
