Purpose: The purpose of present study was to determine the thermal diffusivity of carbon fibre/epoxy composites with different fibre content using flash method. 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 recorded thermograms the thermal diffusivity values were determined for two different heating conditions to verify the effect of heating conditions on thermal diffusivity values. Findings: It was found from obtained results that composites with different carbon fibre content had different values of thermal diffusivity. The method initially proposed by Parker as “flash method” for the thermal diffusivity measurements of homogeneous solids was successfully applied to determine thermal diffusivity of CFRP composites. Relationship showed that the thermal diffusivity is linear function of carbon content in considered materials. Research limitations/implications: Developed relationships between thermal diffusivity and fibre content is not universal for any other carbon fibre reinforced composites (manufactured using different technique and/or using different constituent materials), 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 or laboratory applications to determine thermal diffusivity in carbon fibre reinforced composite materials. Originality/value: The originality of present investigation is in application of transient thermography based on flash method approach to measure thermal diffusivity of carbon/epoxy composites.
