Abstract: A connecting rod comprises a convex elongated body around a longitudinal axis of symmetry and two connecting ends for connecting to adjacent structures. The connecting rod includes two shells with two longitudinal edges that are assembled in these edges and that each have a base of at least one shell web including continuous shell fibers primarily parallel to this axis of symmetry and impregnated with a thermoplastic shell matrix. The connecting rod incorporates at least one assembly web wound around and along the shells, and assembly fibers primarily inclined relative to the axis and impregnated with a thermoplastic assembly matrix remelted in contact with the shell matrix.

Abstract: The present invention relates to a composite connecting rod, an aeronautic ceiling or floor structure incorporating it, and a method for manufacturing this connecting rod. The invention applies to reacting primarily axial forces, in particular in the aeronautics field. The connecting rod comprises a convex elongated body around a longitudinal axis of symmetry and two connecting ends for connecting to adjacent structures, and it includes two shells with two longitudinal edges that are assembled in these edges and that each have a base of at least one shell web including continuous shell fibers primarily parallel to this axis of symmetry and impregnated with a thermoplastic shell matrix. According to the invention, the connecting rod incorporates means for assembling shells comprising at least one assembly web wound around and along shells at said body, and assembly fibers primarily inclined relative to said axis and impregnated with a thermoplastic assembly matrix remelted in contact with the shell matrix.

Abstract: The present invention relates to a connecting rod, an aeronautic floor structure incorporating it, and a method for manufacturing this connecting rod. The invention applies to a connecting rod suitable for reacting primarily axial forces, in particular in the aeronautics field. This connecting rod comprises a tubular body with two ends and two heads for connecting those ends to adjacent structures and that is suitable for reacting primarily axial forces, each head comprising an end-piece flared toward the body and glued on the latter in a gluing interface. According to the invention, the connecting rod comprises at least one first sealing gasket mounted radially between and against the body and the end-piece of each head, axially toward the inside of the gluing interface.

Abstract: A profile with one or more portion(s) whose cross-sections are substantially U-shaped, locally provided with capabilities of increasing torsional rigidity and potentially flexural rigidity, a load-bearing structural element of a vehicle such as a support grille of an electrical and/or hydraulic system incorporating that profile, and a method of manufacturing that profile are provided. The profile includes at least one U-shaped portion having a slot bounded by two wings and a core and that is locally provided and capable for increasing torsional rigidity, the profile being formed of a fibre-reinforced plastic composite, having at least one cross brace formed in the slot from a single part with the wings and the core. The wings and the core are reinforced by fibres mostly oriented in the longitudinal direction of the profile, with more than 60% of the fibres oriented in a ?30° to +30° angle with that direction.
