Benefits of technology
The present invention relates to a golf club head comprising a composite face insert and a variable thickness core material. The composite face insert is made of multiple layers of prepreg plies and a sheet molding compound, which is permanently sandwiched between the layers. The golf club head may also include a face cup, a face insert, a sole, and a crown, and the variable thickness core material may be formed by co-molding the prepreg plies with the sheet molding compound. The invention also provides a method for making the golf club head by sandwiching a sheet molding compound between two layers of prepreg plies and affixing a face cap within the sheet molding compound. The invention allows for improved performance and aesthetics of golf club heads.
Problems solved by technology
Prepreg plies are not the ideal materials to use for golf club face construction, however, because using these materials to create the variable face thickness patterns that are demanded by consumers can be time consuming (the plies must be oriented by hand in a mold), expensive (the cost of plies can be high), and wasteful (scrap parts of the plies cannot easily be reused).

Embodiment Construction
[0032]The present invention provides a solution to the problems set forth above by providing a preferred, combination composite material that can be used to more efficiently make structurally sound golf club parts, including face cups, face inserts, face plates, face patches, soles, crowns, and other parts that require specific and / or continuously variable thicknesses. The present invention also provides face structures that incorporate the novel composite material. The present invention may also be used to make parts for products and devices other than golf clubs.
[0033]As shown in FIGS. 1 and 2, the composite material 10 used to create prior art composite golf club faces typically is made up of multiple prepreg plies 20. Collections of prepreg plies are also referred to as laminates herein. These plies include collections of core-level plies 22, exterior plies 24, and interior plies 26. As noted above, it is both time consuming and expensive to create thickness changes in composite...
