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.
