Abstract : This article concerns the electrical characterization of T700/M21 unidirectional composite materials during the cure with sensors developed for the purpose. It proposes a reliable and reproducible protocol for the characterization of the material during curing. An analysis is carried out to assess the impact of parasitic access elements, which is reduced to a minimum by appropriate dimensioning of the electrodes. A study of the electrical conduction in relation to the direction of the fibres made it possible to establish a suitable approach to homogenized measurement of the material. The use of electrical impedance spectral analysis allows in-situ monitoring of the curing process. The results obtained are compared with those of a rheological analysis of the same material and highlight the value of the proposed protocol.
