Abstract

L invention concerne un procédé d assemblage entre une pièce en matériau métallique (1) et une pièce en matériau composite (2), la jonction entre lesdites pièces étant réalisée au moyen d une fixation de section sensiblement constante reçue dans un premier trou réalisé (11) dans la pièce en matériau métallique et un deuxième trou (3) réalisé dans la pièce en matériau composite. Selon l invention, préalablement à l assemblage entre lesdites pièces, le procédé comporte : -une étape d expansion pour générer un champ de contraintes de compression à la périphérie dudit premier trou (11) et localement dans le matériau constituant la pièce en matériau métallique au moyen d un outil d expansion, -une étape d alésage unique pour réaliser ledit premier trou (11) et ledit deuxième trou (3) ayant un diamètre Ofinal sensiblement supérieur au diamètre de la fixation (9) de manière à laisser un interstice entre la paroi interne desdits trous (3, 11) et la surface externe de la fixation (9), -une étape d assemblage pour positionner la fixation (9) dans lesdits trous (3, 11) pour maintenir la pièce métallique et la pièce composite ensemble.
