The method is for the discriminant monitoring of a composite multi-material assembly () having at least one internal layer () made of a first, electrically conductive composite material and a second layer () made of a second, electrically insulating composite material, the second layer () covering the first internal layer (). The method includes: —preparing the composite multi-material assembly () by exposing a portion () of the internal layer (), which constitutes a first electrode; —applying a second electrode () to the surface of the second layer (), one of these electrodes () being earthed; —performing discriminant monitoring wherein a current is generated between the first electrode () and the second electrode () by applying a threshold voltage Us predetermined by calibration to characterize a lack of structural defects, the appearance of a breakdown at a voltage lower than the threshold voltage Us being indicative of the presence of at least one structural defect in the composite assembly ().
