Purpose: The aim of this paper is to present a model describing heat transfer taking place during thermovision testing of polymer composites. Thermographic tests were undertaken to identify thermal properties of searched material and to correlate them with operational characteristics. Design/methodology/approach: Heat transfer model of thermographic testing stand of our own design was elaborated. The model was applied as a tool of tested material characteristics identification, forming the basis of laminate degradation degree diagnosis. Findings: The most essential result of the project is the physical heat transfer model. Good conformity between model predictions and exemplary experimental results was achieved. The set of physical characteristics describing thermal state of composite was identified and introduced into the model. Research limitations/implications: Experimental results of heat transfer through the composite mounted in thermographic testing stand proved the correctness of developed model. Results of physical properties identification showed the possibility of non-destructive diagnosis of wide class of materials, namely polymeric composites. Practical implications: Results of presented project together with results of planned experimental programme devoted to elaboration of diagnostic relations enable to apply thermography directly to the state of polymeric structural materials assessment. Especially the degree of material degradation may be estimated. Originality/value: Originality of the project is based on possibility of practical application of the model to simulate heat transfer through tested sample mounted in thermographic test stand. Proposed scope of diagnostic tests was not interesting for scientists till now.
