A method of manufacturing a tubular multilayer structure made from a continuous fiber pre-impregnated with a thermoplastic resin includes feeding the material to a shaping station before the material is wound around the mandrel. The material is heated over a shaped hot plate while in the shaping station to lightly melt the material. The material is tensioned to at least 15,000 psi before the material is wound around the mandrel to ensure good bonding of the wound layers.
