Golf club heads and methods to manufacture golf club heads
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 ma include a hollow body portion having a toe portion with a toe portion edge, a heel portion with a heel portion edge, a back portion with a back wall portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and a front portion. A face portion may be coupled to the front portion and include a front surface and a back surface. The body portion includes a face support portion including a composite material and coupled to the back surface of the face portion. The face support portion may include at least one reinforcement portion. Other examples and embodiments may be described and claimed.

5. A golf club head as defined in claim 1 , wherein the at least one reinforcement portion comprises a relatively thicker portion of the base plate portion.
6. A golf club head as defined in claim 1 , wherein the at least one reinforcement portion comprises a rib portion projecting from the base plate portion and extending from a location at or proximate to a first side of the base plate portion to a location at or proximate to a second side of the base plate portion.
7. A golf club head as defined in claim 1 , wherein the face support portion is coupled to the back surface of the face portion with an adhesive.
8. A golf club head comprising:
a body portion having an interior cavity with a front opening;
a face portion coupled to the front opening to close the interior cavity, the face portion comprising a front surface configured to strike a golf ball, a back surface, and a plurality of back groove portions on the back surface of the face portion; and
a face support portion coupled to the back surface of the face portion with an adhesive, the face support portion comprising a composite material.
9. A golf club head as defined in claim 8 , wherein at least two back groove portions of the plurality of back groove portions are connected.
10. A golf club head as defined in claim 8 , wherein the plurality of back groove portions at least partially surround the face support portion.
11. A golf club head as defined in claim 8 , wherein the interior cavity is at least partially filled with a filler material, and where the filler material is coupled to the face support portion.
12. A golf club head as defined in claim 8 , wherein the face support portion comprises at least one reinforcement portion, and wherein the at least one reinforcement portion comprises a relatively thicker portion of the face support portion.
13. A golf club head as defined in claim 8 , wherein the face support portion comprises at least one reinforcement portion, and wherein the at least one reinforcement portion comprises a rib portion projecting from a back surface of the face support portion and extending from a location at or proximate to a first side of the face support portion to a location at or proximate to a second side of the face support portion.
14. A golf club head comprising:
a hollow body portion comprising a toe portion with a toe portion edge, a heel portion with a heel portion edge, a back portion with a back wall portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and a front portion;
a face portion coupled to the front portion, the face portion including a front surface and a back surface; and
a face support portion comprising a composite material and coupled to the back surface of the face portion, the face support portion including at least one reinforcement portion extending from a location at or proximate to a first side of the face support portion to a location at or proximate to a second side of the face support portion.
15. A golf club head as defined in claim 14 , wherein the back surface of the face portion comprises a plurality of back groove portions at least partially surrounding the face support portion.
16. A golf club head as defined in claim 14 , wherein the at least one reinforcement portion comprises a relatively thicker portion of the face support portion.
17. A golf club head as defined in claim 14 , wherein the at least one reinforcement portion comprises a rib portion projecting from the face support portion.
18. A golf club head as defined in claim 14 , further comprising a plurality of connected reinforcement portions.
