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.

A golf club head has a body defining a ball striking face. The body further has a rear portion comprising a plurality of side walls and a planar lower portion. The plurality of side walls extend downward from a top of the golf club head towards the planar lower portion. The body further comprises a cover extending over the rear. The body further defines a gap between the cover and the planar portion.

A ball striking device, such as a golf club head, has a face with a striking surface configured for striking a ball where the face has multiple thickness regions. The face has a center region, an upper region, a lower region, a toe region, and a heel region. The upper and lower regions have a ramped thickness extending from a center region to an upper and lower edge of the face. The heel and toe regions have a constant face thickness and have a thickness less than the other regions. Additionally, the club head body has a flange where the face is welded to the club head body. The flange has a thickness that is greater than the thickness of the heel and toe regions of the face.

A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. The club head can have a non-metallic striking surface positioned at the forward portion of the body.

Described are embodiments of golf club heads having an internal cavity and features that cause the golf club head to have an improved acoustic performance when striking a golf ball. Some embodiments include one or more weight tracks and/or weight ports formed in the sole for receiving adjustable weights. The golf club heads can include one or more internal ribs, thickened wall regions, and/or posts positioned within the cavity that increase the rigidity of the club head and improve the acoustic performance of the club head when striking a ball.

A damper is provided within the cavity of a golf club head and spans substantially the full length of the striking face from heel-to-toe of the golf club head. One or more cutouts and/or other relief is provided in the damper to reduce the surface area of the damper that contacts thep rear surface of the striking face. By reducing the surface area that the damper contacts the rear surface of the striking face, the full length damper improves the sound and feel of the golf club head at impact and only minimally reduces performance of the golf club head. For example, the one or more cutouts and/or other relief maintains face flexibility, characteristic time (CT) and coefficient of restitution (COR) of the striking face.

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components.

A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

Disclosed herein is an iron-type golf club head comprising a body comprising a heel portion, a sole portion, a toe portion, and a topline portion. The topline portion has a mass per unit length of between 0.09 g/mm and 0.40 g/mm. The golf club head also comprises a strike plate coupled to the body at a front portion of the golf club head and a cavity defined between the topline portion, the sole portion, and the strike plate. The golf club head further comprises a bridge bar at a rear portion of the golf club head. The bridge bar spans the cavity, is spaced apart from the strike plate, and is rigidly fixed to and extends uprightly between the sole portion and the topline portion. The bridge bar has a mass per unit length of between 0.09 g/mm and 0.40 g/mm.

Disclosed golf club heads include a body defining an interior cavity, a striking surface, a sole, a crown, and a hosel, which is configured to provide improved aerodynamic and inertia generating properties of the golf club head. Certain embodiments include an inertia generator positioned in the sole between an area proximate the club head's center of gravity and a position toeward of the center of gravity at the rear of the golf club head. Some embodiments include fixed or removable mass elements, weights or weight assemblies positioned in the sole, including, in some instances, within or adjacent to the inertia generator. In particular embodiments, one or more weight assemblies are movably retained within a weight channel defining a path along the sole.
