Abstract: Described herein are embodiments of an iron-type golf club head comprising a rear opening and an insert. The insert either partially or fully occupies the club head interior cavity. The insert damps vibrations occurring within the club head at impact to provide a desirable sound and feel. The insert is formed of a low-density material, thereby providing a significant damping effect while also creating discretionary mass.

Abstract: The golf club head described herein can have a metal body and a non-metal insert. The insert forms an entire toe end of the club head. The insert can have an offset surface, located behind the strike face of the body, wherein the insert and strike face form a gap therebetween. The insert offset surface can comprise a backstop that temporarily restricts bending of a center of the strike face during a golf ball impact. The gap between the strike face and the insert allows the strike face to flex while the backstop prevents the strike face from over flexing. In one embodiment, the golf club head can comprise a body having an interior cavity that opens towards a toe end. The insert can form an outermost surface of the toe end and fill a portion of the cavity.

Abstract: A golf club head includes a resilient member extending from a sole of the club head to the crown. The resilient member has a convex, arcuate shape relative to a strike face of the club. The resilient member has a rest state prior to impact with a golf ball, in which the resilient member defines a first chord length, and a deflected state during impact with a golf ball, in which the resilient member defines a second chord length that is greater than the first chord length. The resilient member improves impact response of the strike face to allow strike face thickness to be reduced while maintaining durability of the golf club head.

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 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 heads with components composed of a metal-composite-metal construction are described herein. The metal-composite-metal construction makes up a portion of the golf club head. The metal-composite-metal construction can make up any one or combination of the following structures: faceplate, face insert, internal ribs, turbulators, crown insert, or weight channel. The composite layer of the metal-composite-metal construction is composed of reinforced fibers. The metal-composite-metal construction allows for weight savings in the golf club head while maintaining durability, strength, rigidity, and performance.

Abstract: A golf club head includes a front body and a rear body coupled to the front body to define a hollow cavity therebetween. The front body includes a strike face that defines a ball striking surface, a hosel, and a frame that at least partially surrounds the strikeface and extends rearward from a perimeter of the strikeface away from the ball striking surface. The strike face and frame are formed from a thermoplastic composite comprising a thermoplastic polymer having a plurality of discontinuous fibers embedded therein. Each of the plurality of discontinuous fibers have a length between about 0.01 mm and 3 mm. In some embodiments, the thermoplastic composite is 30% to 70% fibers by volume.

Abstract: Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein.
