Purpose: Primary purpose of the present experimental study was to evaluate the local fibre content in carbon fibre/epoxy composites using transient thermography. Design/methodology/approach: The experiments have been performed using transient thermography to obtain the thermograms for carbon/epoxy specimens with different carbon fibre content. From obtained thermograms the thermal diffusivity values were determined and compared for each specimen and correlated with carbon content. The composites were two times tested using two different heating conditions to check the conformity of determined diffusivity values. Findings: It was found from obtained results that composites with different carbon fibre content had different values of thermal diffusivity, indicating that transient thermography can be considered as a non-destructive testing method for fiber content evaluation in CFRP composites. Research limitations/implications: Developed empirical formula is not universal for any other fibre reinforced polymer composite, so different relationships should be determined for different composites. Practical implications: The results obtained from present experiment would be of great importance in the industrial applications to obtain first estimate of carbon fibre content in fibre reinforced composite materials. Originality/value: The originality of present investigation is in application of transient thermography for local fibre content evaluation in polymer composite materials. The method should be of interest for the industrial quality control applications and is of great importance for composite products with high failure-free requirements.
