A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Some embodiments of the lightweight golf clubs described herein include a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate to maximize performance gains (e.g., ball travel distance, impact efficiency, and ball speed) targeted to individuals with swing speeds less than 85 mph. As will be further described below, in order to achieve a lightweight golf club head (having a thin crown, a thin sole, a mass efficient weight system, and a thin faceplate), the golf club head further comprises a crown-to-faceplate bridge and a sole-to-faceplate bridge to control the characteristic time (CT) properties of the golf club head.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club heady may include a body portion having an interior cavity with a front opening, a face portion coupled to the front opening to close the interior cavity, a plurality of back groove portions on a back surface of the face portion, a mass portion coupled to the body portion, a polymer filler material in the interior cavity, and a face support portion coupled to the back surface of the face portion. Each groove portion of the plurality of back groove portions is located between the face support portion and a perimeter edge of the face portion. Other examples and embodiments may be described and claimed.

A hollow golf club head includes a metallic front body coupled with a composite rear body. The front body includes a strike face and a surrounding frame that extends rearward from a perimeter of the strikeface. The rear body includes a crown member coupled with a sole member. The sole member has a structural layer formed from a filled thermoplastic material, while the resilient layer is bonded to the external surface of the structural layer and is formed from a fiber-reinforced thermoplastic composite material. The resilient layer has an opening through which a metallic weight pad at least partially extends. The weight pad is bonded to the structural layer and includes an aperture for attaching a metallic weight. The golf club head can also have one or more structural members that are upright and connect the weight pad to the crown member.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head includes a front portion. A face portion is coupled to the front portion. The face portion includes a central strike portion and a perimeter. A plurality of projections extend from the face portion to provide a ball striking surface for impacting a golf ball. Each projection is defined by a plurality of grooves intersecting one another within the face portion. The plurality of projections are each defined by an area ratio between a base portion area and a peak portion area. The area ratios of the plurality of projections decrease from the central strike portion to the perimeter of the face portion. Other examples may be described and claimed.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a recessed opening between a front opening and a back wall portion, a front plate portion coupled to the recessed opening to enclose a first interior cavity in the golf club head between the front plate portion and the back wall portion, a face portion coupled to a front portion to enclose a second interior cavity between the face portion and the front plate portion, a first filler material at least partially filling the first interior cavity, and a second filler material at least partially filling the second interior cavity. The first filler material and the second filler material have at least one different physical property. Other examples and embodiments may be described and claimed.
