Process for bonding two parts subjected to tensile forces, bonded parts obtained

摘要

A process for producing a bonded connection between first and a second parts, with a length of superposition around a longitudinal axis, these parts being subjected to forces in at least one longitudinal direction, includes producing a bonded connection having at least one interior and/or exterior adhesive joint, over the length between the parts, the joint having a cross-section around the longitudinal axis, the thickness of the joint varying from a free edge on the end-fitting side, to the other free edge on the tube side, and following the direction of forces to which the parts are subjected so as to better distribute the overstresses over at least one part of the length. At least one adhesive joint is produced, having in the longitudinal direction a large thickness facing each of two free edges relative to the thickness in a median part.

1. A process for production of a bonded connection between a tube and an end fitting, with a length of superposition around a longitudinal axis of the tube and the end fitting, the tube and the end fitting being subjected to forces in at least one longitudinal direction, the process comprising:
producing the bonded connection comprising at least one adhesive joint over at least one part of a length between the tube and the end fitting, said at least one adhesive joint comprising at least one of the group consisting of i) an interior adhesive joint and ii) an exterior adhesive joint over the at least one part of the length between the tube and the end fitting, said at least one adhesive joint having a closed or semi-closed cross-section around the longitudinal axis of the connection, a thickness of said at least one adhesive joint varying from a first free edge on an end-fitting side, to a second free edge on a tube side of said at least one adhesive joint and following a direction of forces to which the tube and the end fitting are subjected in such a way as to better distribute overstresses over the at least one part of said length between the tube and the end fitting, wherein at least one adhesive joint is produced, having, in the longitudinal direction being subjected to the forces, a larger thickness facing each of said first and second free edges relative to a thickness of said at least one adhesive joint in a median part said at least one adhesive joint.
