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.

A ducting and associated method is provide in which the ducting includes a pipe with a thermoplastic or thermoplastic elastomeric layer and a reinforcing layer. The pipe has a curved or bent geometry and the reinforcing layer is made of a composite material based on reinforcement in intimate and direct contact with the subjacent layer. The geometry is obtained by hot forming the inner layer to give the geometry, and the reinforcement is either impregnated with a thermosetting matrix to form a thermosetting composite, or reinforcing fibers are intermixed with thermoplastic fibers or powders, or impregnated with a plastic polymeric coating that is curable chemically. Alternatively, the inner layer is first covered with the reinforcing layer in which the reinforcement includes reinforcing fibers intermixed with a thermoplastic material in the form of fibers, film or powder is blow-molded to give the pipe its final geometry.

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. The connecting rod can be manufactured by assembling the first seal in contact with each end-piece and a first inner or outer face of an end zone opposite the body, then gluing each end-piece on the body, by injection and suction of a glue radially between the body and each end-piece and axially toward the outside of this first sealing gasket.
摘要:
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.

A link arm for connecting a first unsuspended mass to a second suspended mass, and its manufacturing method are provided. In some embodiment the arm applies in particular to a suspension system for a motor vehicle, wherein the arm is able to equip a wheel suspension by having triangular housings to receive a stub axle of the wheel and two connecting links to the chassis of the vehicle. In some embodiments, the arm comprises housings to receive a first linkage joint to the first mass, and at least a second linkage joint to the second mass, and comprises: a stiffening portion which comprises a first thermoplastic or thermosetting matrix composite material reinforced with fibers and which comprises a peripheral rim of the arm, and an anti-buckling portion interposed in the stiffening portion and extending from the rim over substantially the entire arm.
