Abstract

L’invention concerne une pièce (10), notamment pour une turbomachine (100) d’aéronef, comportant :- un corps (40) creux délimitant une cavité interne en matériau composite réalisé à base de fibres noyées dans une résine, la cavité interne étant remplie d’un matériau de remplissage (43),- un capteur de fissuration (50) apte à détecter une fissuration de la pièce (10) entre le matériau composite du corps et le matériau de remplissage, et comprenant un fil conducteur (51) agencé dans le matériau composite et le matériau de remplissage et s’étendant dans une zone (Z1) de la pièce dans laquelle la présence d’une fissuration doit être surveillée, et- un élément de liaison (60) relié au capteur de fissuration et configuré pour transmettre un signal (S) lorsqu’une fissuration est détectée en mesurant la résistance du fil et la comparant à un seuil prédéterminé. Figure pour l'abrégé : Figure 3
