Abstract: A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process.

Abstract: A tubular part with a complex geometrical shape, the tubular part is made of a composite material including, on the one hand, a core part made of a very high-temperature resin obtained by a 3-D direct-creation method using a very high-temperature thermoplastic resin and, on the other hand, a coating of resin-impregnated fibres. The part includes, for example, at least one internal separation of the tube into several conduits that do not communicate with one another. The part is suitable for conveying air flows in opposite or separate directions. One of the conduits can be a dedicated cable raceway.

Abstract: A method for making parts (6) having a complex geometrical shape, the geometrical shape including e.g. various bends, branching, deflectors, sections or thickness, that includes the steps of: forming a core part (1) having a geometry substantially similar to that of the target shape, except for the outer thickness, using a three-dimensional creation method; wrapping at least a portion of the core part with fibres previously or subsequently impregnated with resin until the final dimensions of the target shape are reached; and curing the resin.
