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 including a first material and having a toe portion, a heel portion, a top portion, a sole portion, a back portion, a front portion having a face portion. The golf club head may also include a third mass portion including a second material and coupled to the body portion, and a plurality of mass portions coupled to the third mass portion. The density of the second material is greater than a density of the first material. The interior cavity may include an elastic polymer material. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

a body portion associated with a first mass and made of a first material, the body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity partially or entirely filled with a polymer material associated with a first coefficient of restitution (COR) greater than or equal to 0.7 when an initial velocity is greater than or equal to 100 feet per second;

at least one mass portion associated with a second mass and made of a second material, the at least one mass portion located at or below a horizontal midplane of the golf club head;

a port connected to the interior cavity; and

a face portion having a thickness of less than or equal to 1.905 millimeters (0.075 inch),

wherein the first mass is greater than or equal to the second mass,

wherein the golf club head is associated with a second COR, and

wherein the first and second CORs are associated with a COR ratio of less than two (2).

2. A golf club head as defined in claim 1, wherein the COR ratio comprises a ratio in a range from about 0.8 to about 1.2.

3. A golf club head as defined in claim 1, wherein the at least one mass portion comprises a tungsten material.

4. A golf club head as defined in claim 1, wherein the interior cavity is partially or entirely filled with the polymer material from the port.

5. A golf club head as defined in claim 1, wherein the first COR comprises a COR greater than 0.7 and less than or equal to 0.9 when the initial velocity is greater than 100 feet per second.

6. A golf club head as defined in claim 1 further comprising a bonding portion configured to bond the polymer material to the face portion.

7. A golf club head as defined in claim 1 further comprising a bonding portion configured to bond the polymer material to the face portion, wherein a ratio of the thickness of the face portion and a thickness of the bonding portion is greater than or equal to 0.1 and less than or equal 4.0.

8. A golf club head comprising:

a body portion made of a first material, the body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity partially or entirely filled with a second material associated with a first coefficient of restitution (COR) greater than or equal to 0.7 when an initial velocity is greater than or equal to 100 feet per second; and

at least one mass portion made of a third material, the at least one mass portion located at or below a horizontal midplane of the golf club head,

wherein the golf club head is associated with a second COR, and

wherein the first and second CORs are associated with a COR ratio.

9. A golf club head as defined in claim 8, wherein the second material comprises an elastic polymer material.

10. A golf club head as defined in claim 8, wherein the COR ratio comprises a ratio of less than two (2).

11. A golf club head as defined in claim 8, wherein the COR ratio comprises a ratio in a range from about 0.8 to about 1.2.

12. A golf club head as defined in claim 8, wherein the first COR is greater than 0.7 and less than or equal to 0.9 when the initial velocity is greater than 100 feet per second.

13. A golf club head as defined in claim 8 further comprising a bonding portion configured to bond the second material to the face portion, wherein a ratio of a thickness of the face portion and a thickness of the bonding portion is greater than or equal to 0.1 and less than or equal to 4.0.

14. A golf club head as defined in claim 8, wherein the interior cavity is associated with an interior cavity volume, and wherein the interior cavity volume is related to a body portion volume by equation 0.2≦

V_c/V_b≦

0.5, where V_c is the interior cavity volume in units of in³, and V_b is the body portion volume in units of in³.

15. A golf club head comprising:

a body portion made of a first material, the body portion having a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity;

a face portion having a thickness; and

a cavity filling portion configured to partially or entirely fill the interior cavity, the cavity filling portion having a first portion and a second portion made of a second material, the first portion of the cavity filling portion configured to attach the second portion of the cavity filling portion to the face portion, the second portion of the cavity filling portion having a coefficient of restitution (COR) greater than or equal to 0.7 when an initial velocity is greater than or equal to 100 feet per second, and

wherein a ratio of the thickness of the face portion and a thickness of the first portion of the cavity filling portion is greater than or equal to 0.1 and less than or equal to 4.0, and

wherein the first material is different from the second material.

16. A golf club head as defined in claim 15, wherein the first portion of the cavity filling portion comprises an epoxy material, and wherein the second portion of the cavity filling portion comprises an elastic polymer material.

17. A golf club head as defined in claim 15, wherein a thickness of the face portion is related to the volume of the polymer material by equation 0.01≦

T_f/V_e≦

0.2, where T_f is the thickness of the face portion in units of inches, and V_e is the volume of the second material in units of in³.

18. A golf club head as defined in claim 15, wherein the interior cavity is associated with an interior cavity volume, and wherein the interior cavity volume is related to a body portion volume by equation 0.2≦

V_c/V_b≦

0.5, where V_c is the interior cavity volume in units of in³, and V_b is the body portion volume in units of in³.

19. A golf club head as defined in claim 15, wherein the COR of the second portion of the cavity filling portion comprises a COR greater than 0.7 and less than or equal to 0.9 when the initial velocity is greater than 100 feet per second.
