摘要：
An in-situ melt processing method for forming a fiber thermoplastic resin composite overwrapped workpiece (200), such as a composite overwrapped pressure vessel. Carbon fiber, or other types of fiber, are combined with a thermoplastic resin system. The selected fiber tow (145) and the resin are prepared for impregnation of the tow by the resin. The resin is melted; and, carbon fiber is impregnated with the melted resin at the filament winding machine delivery head. The molten state of the composite is maintained and is applied, in the molten state, to the heated surface of a workpiece (200). The portion of the surface being wrapped is heated to the melting point of the thermoplastic resin so that the molten composite more efficiently adheres to the heated surface of the workpiece (200) and so that the uppermost layer of fiber resin composite is molten when overwrapped resulting in better adherence of successive layers to one another.
