An in-situ melt process for creating a fiber resin composite overwrap, said in-situ melt process comprising the steps of: - selecting a fiber tow consisting of unimpregnated fibers; - selecting a thermoplastic resin compatible with said selected fiber tow; - preparing said fiber tow for impregnation by said selected thermoplastic resin, wherein the step of preparing said fiber tow for impregnation by said thermoplastic resin includes the steps of drying said fiber tow, spreading said fiber tow to a selected bandwidth, and heating said fiber tow to a selected temperature, wherein said selected temperature is approximately a melting point of said selected thermoplastic resin; - preparing said thermoplastic resin for impregnation into said fiber tow; - reducing viscosity of said thermoplastic resin by heating said thermoplastic resin to a melting point of said thermoplasitic resin; - impregnating said prepared molten thermoplastic resin into said prepared fiber tow in close proximity to a filament winding head, thereby creating a molten fiber resin composite towpreg; - heating a selected portion of a workpiece to said melting point of said thermoplastic resin; - applying a first layer of said molten fiber resin composite towpreg to said heated surface of said workpiece whereby a molten state of said molten fiber towpreg is maintained during a wrapping procedure thereby resulting in said molten fiber resin composite towpreg more efficiently adhering to the heated surface of the workpiece; - heating a selected portion of a previously applied layer of said fiber resin composite towpreg, wherein said previously applied layer of said fiber resin composite towpreg is melted prior to applying an additional layer of molten fiber resin composite towpreg wherein said heat is applied directly to the outermost surface of the overwrap and a surface of the workpiece is maintained at a temperature approximating the thermoplastic resin's melting temperature; - applying an additional layer of molten fiber resin composite towpreg to said molten previously applied layer of fiber resin composite towpreg whereby applying said molten fiber resin composite towpreg to an area of molten fiber resin composite towpreg previously applied to said workpiece allows successive molten fiber resin composite towpreg layers to adhere to one another and further allows individual filaments within said molten fiber resin composite towpreg to slide relative to one another, thereby effectively eliminating catenary, wrinkles, and creases within the fiber resin composite overwrap; and - compacting and consolidating said molten fiber resin composite towpreg layers to one another under pressure thereby removing entrapped air. - selecting a fiber tow consisting of unimpregnated fibers;
