Purpose: The aim of this paper is to present results of application of ultrasonic and termovision techniques to non-destructive evaluation of the degree of thermal degradation of fibre reinforced polymer composites. a model describing heat transfer taking place during. Thermographic tests were undertaken to identify thermal properties of searched material and to correlate them with operational characteristics. In the same manner ultrasounds propagation characteristics were correlated with strength properties. Design/methodology/approach: Epoxy-glass composites were exposed to thermal ageing and subsequently tested using thermography and ultrasounds. Finally destructive bending test was performed. Material characteristics evaluated in these test were compared and related to elaborate diagnostic relations. Findings: The most essential result of the project is the methodology of applying thermovision and ultrasonic testing to diagnose the state of thermal degradation of polymeric composites. Research limitations/implications: Results showed the possibility of non-destructive diagnosis of the degree of thermal degradation manifested by strength capacity deterioration 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 and ultrasonic testing 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 thermovison and ultrasonic testing to non-destructive diagnosis of kinematics of degradation processes.
