Abstract: Some embodiments include club heads having reinforced club head faces. In one example, the club head comprises a variable face thickness with thickened and thinned regions. The face includes a thinned perimeter region positioned near a perimeter of the face, and a thickened central region positioned over a geometric center of the face. The club head further comprises a 360 undercut that extends along the entire perimeter of the face. The combination of the thinned perimeter region, thickened central region, and 360 undercut reinforces the club head while permitting the face to bend. Other embodiments of related club heads and methods are also disclosed.

Abstract: Some embodiments include club heads having reinforced club head faces. Other embodiments of related club heads and methods are also disclosed.

Abstract: Described herein is a golf club head comprising a composite material, the golf club head further comprising: a front end having a bottom rail, a top rail, and a strikeface, the strikeface including a striking surface, a back surface, and a reinforcement element extending from the back surface of the strikeface; a rear end opposite the front end; a heel portion; a toe portion opposite the heel portion; a sole coupled to the front end along the bottom rail at a sole transition region, the sole extending toward the rear end of the golf club head and including a sole thickness, a first weight member and a second weight member, and a perimeter wall extending from the front end near the heel portion to the front end near the toe portion along the rear end of the golf club head, wherein the perimeter wall decreases in height from the front end toward the rear end of the golf club head.

Abstract: Disclosed herein is a golf club heads having a body portion and a face portion, wherein the face portion comprises a variable thickness profile disposed at an angle on the rear surface of the face plate.

Abstract: Embodiments of golf club heads comprising a face with a variable thickness to improve the durability in the club head, increase ball speed, and increase characteristic time (CT) are described herein. The face comprises thickened and thinned regions. The face includes a perimeter thickened region positioned near a perimeter of the face, a thinned region positioned inward of the perimeter thickened region toward a center of the face, and a central thickened region positioned over the center of the face. The combination of the thickened and thinned regions of the face increase ball speed and further increase or maximize CT without sacrificing durability.

Abstract: A golf club head includes a rear body having a crown member coupled to a sole member, and a front body coupled to the rear body to define a substantially hollow structure. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strike face. At least a portion of an outer wall of the club head comprises a thermoplastic composite having a plurality of lamina layers. The plurality of lamina layers include at least a fabric reinforced thermoplastic composite layer and a filled thermoplastic layer, and the fabric reinforced thermoplastic composite layer and the filled thermoplastic layer are directly bonded to each other without an intermediate adhesive.

Abstract: Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

Abstract: Embodiments of golf club heads having adjustable weighting systems with a plurality of discrete attachment locations capable of receiving one or more weights are described herein. The golf club heads described herein provide user adjustability of club head center of gravity to adjust ball flight while maintaining a high moment of inertia and low and back center of gravity position.

Abstract: Described herein is a hollow body iron-type golf club head having a sole and ballast configured to relieve stress within a forward portion of the sole. In a first configuration, the golf club head comprises a ballast undercut for relieving stress. In other configurations, the ballast undercut is combined with additional stress relief features, such as a cascading sole near the face sole juncture, for further reductions to face thickness.
