Abstract

A process and apparatus are provided for forming filament wound composite workpieces. The process comprises the steps of: providing reinforcement material; providing an injection die; providing a winding apparatus including a rotatable mandrel; passing the reinforcement material through the injection die; injecting a resin material into the injection die to impregnate the reinforcement material with the resin material to form impregnated reinforcement material; and winding the impregnated reinforcement material about the mandrel so as to form a composite workpiece.
