    Abstract: A method of processing a thermoplastic composite tubular lineal comprising providing a pre-pregged thermoplastic composite around an elongated stationary mandrel; wrapping the pre-pregged thermoplastic composite with a release material; heating the stationary mandrel so that the pre-pregged thermoplastic composite melts and the release material contracts, exerting pressure on the pre-pregged material; cooling the pre-pregged material and release material so as to form a thermoplastic composite tubular lineal in its final configuration; pulling the thermoplastic composite tubular lineal downstream; and removing the release material from the thermoplastic composite tubular lineal.
