Abstract

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a top portion, a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, an interior, and a cover portion. The cover portion may include a plurality of layers. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a body portion comprising a top portion, a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, and an interior;

an opening in the top portion; and

a cover portion attached to the body portion and covering the opening in the top portion, the cover portion comprising;

a structural top layer comprising a fiber composite material;

a noise-dampening middle layer comprising a polymer material, the noise-dampening middle layer bonded to the structural top layer; and

a structural bottom layer comprising a fiber composite material, the structural bottom layer bonded to the noise-dampening middle layer,

wherein the structural bottom layer is bonded to the top portion to attach the cover portion to the body portion.

2. A golf club head as defined in claim 1, wherein an outer surface of the cover portion is flush with an outer surface of the top portion.

3. A golf club head as defined in claim 1, wherein the polymer material is an elastomer.

4. A golf club head as defined in claim 1, wherein the noise-dampening middle layer is bonded to the structural top layer by an adhesive.

5. A golf club head as defined in claim 1, wherein the cover portion is bonded to the top portion by one or more adhesives.

6. A golf club head as defined in claim 1 further comprising a reinforcement portion extending across the opening.

7. A golf club head as defined in claim 1 further comprising a reinforcement portion extending across the opening, the reinforcement portion having a width between 3% and 15% of a distance between the toe portion and the heel portion.

8. A golf club head comprising:

a body portion comprising a top portion, a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, and an interior;

an opening in the top portion; and

a cover portion attached to the body portion and covering the opening in the top portion, the cover portion comprising;

a first layer comprising a composite material, the first layer being a structural layer;

a second layer adjacent to and bonded to the first layer, the second layer comprising a polymer material, the second layer being a noise dampening layer; and

a third layer adjacent to and bonded to the second layer, the third layer comprising a composite material, the third layer being a structural layer.

9. A golf club head as defined in claim 8, wherein the composite material of the first layer is a fiber composite material.

10. A golf club head as defined in claim 8, wherein the composite material of the first layer is a graphite-epoxy composite material.

11. A golf club head as defined in claim 8, wherein the composite material of the third layer is a fiber composite material.

12. A golf club head as defined in claim 8, wherein the composite material of the third layer is a graphite-epoxy composite material.

13. A golf club head as defined in claim 8, wherein the second layer is bonded to the first layer by an adhesive.

14. A golf club head as defined in claim 8, wherein the third layer is bonded to the second layer by an adhesive.

15. A golf club head comprising:

a body portion comprising a crown portion, a bottom portion, a toe portion, a heel portion, a front portion, a rear portion, and an interior;

an opening in the crown portion; and

a cover portion attached to the body portion and covering the opening in the crown portion, the cover portion comprising;

a first layer comprising a composite material, the first layer being a structural layer;

a second layer adjacent to and bonded to the first layer, the second layer comprising a polymer material, the second layer being a vibration-isolating layer; and

a third layer adjacent to and bonded to the second layer, the third layer comprising a composite material, the third layer being a structural layer.

16. A golf club head as defined in claim 15, wherein the opening comprises a shoulder that supports the cover portion.

17. A golf club head as defined in claim 15, wherein the opening comprises a shoulder that supports the cover portion, and wherein an outer surface of the cover portion is flush with an outer surface of the crown portion.

18. A golf club head as defined in claim 15, wherein the crown portion comprises a reinforcement portion extending across the opening.

19. A golf club head as defined in claim 15, wherein the polymer material of the second layer is a thermoplastic polyurethane material.

20. A golf club head as defined in claim 15, wherein the polymer material of the second layer is a thermoplastic elastomer material.
