摘要
Non-destructive method for detecting zones with non-conductivematerials, such as materials that includeglass fibres, in a part made of a conductive composite,such as a composite whose reinforcing fibres are carbonfibres, provided with an organic coating, thatcomprises the following stages: a) providing a devicefor applying an electric potential on the surface ofsaid part; b) determining the dielectric breakdownpotential Pr corresponding to the thickness E of thecoating; c) applying said dielectric breakdownpotential Pr with said device to the part for thepurpose of identifying those zones that have non-conductivematerials when dielectric breakdown does notoccur in them.
