Abstract: A composite material comprising a plurality of fiber tape strips woven or braided together. Each of the plurality of fiber tape strips is made of a single layer of unidirectional fibers. The fibers are at least partially embedded in a thermoplastic matrix. A tubular composite part is made from this composite material and of an internal film. A method of manufacturing the composite material comprises weaving or braiding the fiber tape strips, especially in the form of a tube. A method of manufacturing a composite part comprises pressurizing the film inside the tube while heating both the tube and the film up to their forming temperature so as to bond the film to the woven fiber tape strips.

Abstract: A tool for manufacturing a part made of a sheet of thermoplastic material comprises a female die and a male die. The female die has a cavity, whose wall has a bottom portion and a top portion. The male die has a backing structure, a support attached to the backing structure and a heat-resistant bladder. The bladder has an inlet for connection with a source of compressed fluid. The support is used to support the bladder. The male die further comprises a base attached to the bladder. The base is deformable so as to enter the cavity of the female die. The bladder is adapted to apply a pressure substantially perpendicular to the cavity wall. The base is adapted and positioned to deform the thermoplastic sheet upon entering the cavity by making the thermoplastic sheet first contact the bottom portion of the wall. The bladder expends while applying a pressure on the thermoplastic sheet against the wall from the bottom portion to the top portion.
