Abstract
L’invention concerne un procédé de fabrication d’un pièce (20) en matériau composite, notamment pour une turbomachine d’aéronef, ladite pièce comportant : - un corps (21) comprenant un renfort fibreux (22), tissé et densifié par une matrice, le corps comprenant une surépaisseur (se) prédéterminée de matrice agencée dans une zone à préparer (Z1) du corps, et - un élément de détection (25) de l’atteinte de l’intégrité physique du renfort fibreux dans la zone à préparer. Selon l’invention, le procédé comprend les étapes suivantes : - agencement de l’élément de détection, dans ou sur le renfort fibreux, qui comprend un fil conducteur (27) entouré d’une gaine isolante (28), - injection d’une matrice dans le renfort fibreux, - densification de la matrice avec le fil conducteur, - préparation de surface où une épaisseur prédéterminée de matrice est supprimée, - mesure de la valeur de la résistance du fil conducteur.
