This paper presents experimental testing of samples from two unidirectional Carbon Fibre Composite (CFC) panels to determine the factors that influence the electrical properties of CFCs and to also determine the temperature co-efficient of resistance. The CFC panels were manufactured by two different techniques to compare the impact of the manufacturing process on the electrical properties. Various electrical conductivity measurement methods were evaluated to determine the most consistent and

... curate technique. The influence of sample geometry on the measured electrical conductivity was also investigated. Thermal imaging was used to image resistive losses and illustrate the current paths through the fibres within the CFC test samples. Finally, the effects of increasing temperature on the CFC samples are presented, illustrating that CFCs have a negative temperature co-efficient.
