Abstract

A method of fabricating a composite vessel encompassing rapid manufacturing. The process includes using a liner, of metal or plastic materials, over which a braided or developed preform is wrapped. The dry fiber wrapped liner is placed in a mold and resin injected into the cavity formed between the liner and the mold outer walls. The liner is flooded with heated and/or cooled pressurized fluid thus enabling complete and independent process control from within the liner for both the resin injection and the cure phases. Fiber placement control is determined through combined biaxial and triaxial braid/preform design, and by wrapping at controlled tension onto the supporting liner. Fiber tension control is further enhanced by the methodology of mold loading whereby tensioning forces are enacted during actual load and close. The process may use thermoset or thermoplastic resins and any of a variety fibrous reinforcements.
