ABSTRACT:
A method of manufacturing a one piece, composite, hockey stick in an autoclave. A mandrel is provided which has a non uniform cross section. Pre-preg flags are wrapped around the mandrel. Provision is made so that when the wrapped mandrel is inserted in a pressure application tube, a portion of the wrapped mandrel is separated from the pressure application tube by one or more spacers. Pressure is then applied to the pressure application tube which in turn applies the pressure to the spacers. The spacers then apply the pressure to the wrapped mandrel to compact the pre-preg on the wrapped mandrel. Next the spacers are removed and the pre-preg is cured. Finally, a blade is formed around the pre-preg flag.
