A process for producing a bonded connection between a first and a second part, 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 a portion of the length between the parts, the joint having a closed or semi-closed 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 its two free edges relative to the thickness in its median part.
Process for the production of a bonded connection (40) between a first part (42) and a second part (44), with a length (L) of superposition around a longitudinal axis (L40), these parts (42, 44) being subjected to forces (T) in at least one longitudinal direction, the process consisting in producing a bonded connection (40) comprising at least one interior adhesive joint (46) and/or one exterior adhesive joint (48), over at least one part of the length (L) between the said two parts (42, 44), such a joint (46, 48) having a closed or semi-closed cross-section around the longitudinal axis (L40) of the connection (40), the thickness of an adhesive joint (46, 48) varying from a free edge (50), on the end-fitting side, to the other free edge (52), on the tube side, of said joint (46, 48) and following the direction of forces to which the first and second parts are subjected in such a way as to better distribute the overstresses over the at least one part of said length (L),
Tube (42) and end fitting (44) comprising at least one bonded surface (S1, S2) between them, with the end fitting (44) comprising a peripheral groove (54), recessed, in such a way as to accommodate by interlocking one end of the tube (42) over a superposition length (L), the tube (42) and the end fitting (44) being connected by at least one bonded connection (40) comprising at least one interior adhesive joint (46) and/or one exterior adhesive joint (48) over at least one part of the length (L) between the two said parts (42, 44) and around a longitudinal axis (L40), such a joint (46, 48) having a closed or semi-closed cross-section around the longitudinal axis (L40) of the connection (40), and the thickness of an adhesive joint (46, 48) varying from one free edge (50), on the end-fitting side, to the other free edge (52), on the tube side, of said joint (46, 48), wherein at least one adhesive joint (46, 48) has a larger thickness facing each of its two free edges (50, 52) relative to the thickness of said at least one adhesive joint (46, 48) in its median part.
