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 front portion, a rear portion, a toe portion, a heel portion, a bottom portion, a top portion, and a crown portion covering an opening in the top portion. The crown portion may include an upper plurality of composite layers, a lower plurality of composite layers, and one or more integral ribs disposed between the upper and lower pluralities of composite layers. Other examples and embodiments may be described and claimed.

Claims

1. A golf club head comprising:

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

a crown portion attached to the top portion and covering the opening, the crown portion comprising;

an upper plurality of composite layers;

a lower plurality of composite layers;

a crown stiffening portion disposed between the upper plurality of composite layers and the lower plurality of composite layers, the crown stiffening portion comprising;

a first integral rib extending from a front perimeter of the crown portion toward a rear perimeter of the crown portion, the first integral rib comprising a plurality of composite layers; and

a second integral rib extending from the front perimeter of the crown portion toward the rear perimeter of the crown portion, the second integral rib comprising a plurality of composite layers.

2. A golf club head as defined in claim 1, wherein the upper plurality of composite layers comprises an outer structural layer comprising carbon fibers and resin.

3. A golf club head as defined in claim 1, wherein the lower plurality of composite layers comprises an inner structural layer comprising glass fibers and resin.

4. A golf club head as defined in claim 1, wherein the plurality of composite layers of the first integral rib comprise carbon fibers and resin.

5. A golf club head as defined in claim 1, wherein the plurality of composite layers of the second integral rib comprise carbon fibers and resin.

6. A golf club head as defined in claim 1, wherein the first and second integral ribs diverge in a direction from front to rear in the crown portion.

7. A golf club head as defined in claim 1, wherein a composite layer in the first integral rib has a width at least 5% greater than a width of an adjacent composite layer in the first integral rib.

8. A golf club head as defined in claim 1, wherein a composite layer in the second integral rib has a width at least 5% greater than a width of an adjacent composite layer in the second integral rib.

9. A golf club head comprising:

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

a crown portion attached to the top portion and covering the opening, the crown portion comprising;

an upper plurality of composite layers;

a lower plurality of composite layers; and

a crown stiffening portion disposed between the upper plurality of composite layers and the lower plurality of composite layers, the crown stiffening portion comprising;

a toe-side integral rib extending from a front perimeter of the crown portion to a rear perimeter of the crown portion, the toe-side integral rib comprising a plurality of composite layers;

a heel-side integral rib extending from the front perimeter of the crown portion to the rear perimeter of the crown portion, the heel-side integral rib comprising a plurality of composite layers; and

a central integral rib extending along the front perimeter of the crown portion and connecting the toe-side integral rib to the heel-side integral rib, the central integral rib comprising a plurality of composite layers.

10. A golf club head as defined in claim 9, the crown portion further comprising a central crown portion extending from the toe-side integral rib to the heel-side integral rib and extending from the central integral rib to the rear perimeter of the crown portion, wherein the central crown portion has a maximum height that is greater than a maximum height of a toe-side crown portion and greater than a maximum height of a heel-side crown portion.

11. A golf club head as defined in claim 9, wherein the crown portion further comprises a toe-side crown portion, a heel-side crown portion, and a central crown portion located between the heel-side crown portion and the toe-side crown portion, the central crown portion having a maximum height that is greater than a maximum height of the toe-side crown portion and greater than a maximum height of the heel-side crown portion.

12. A golf club head as defined in claim 9, wherein the crown portion further comprises:

a toe-side crown portion, a heel-side crown portion, and a central crown portion located between the heel-side crown portion and the toe-side crown portion, the central crown portion having a maximum height that is greater than a maximum height of the toe-side crown portion and greater than a maximum height of the heel-side crown portion;

a first contoured transition region extending between and separating the toe-side crown portion and the central crown portion, and

a second contoured transition region extending between and separating the heel-side crown portion and the central crown portion.

13. A golf club head as defined in claim 9, wherein the crown portion further comprises:

a toe-side crown portion, a heel-side crown portion, and a central crown portion located between the heel-side crown portion and the toe-side crown portion, the central crown portion having a maximum height that is greater than a maximum height of the toe-side crown portion and greater than a maximum height of the heel-side crown portion;

a first contoured transition region extending between and separating the toe-side crown portion and the central crown portion; and

a second contoured transition region extending between and separating the heel-side crown portion and the central crown portion,

wherein the toe-side integral rib is disposed within the first contoured transition region, and

wherein the heel-side integral rib is disposed within the second contoured transition region.

14. A golf club head comprising:

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

a crown portion attached to the top portion and covering the opening, the crown portion comprising;

an upper plurality of composite layers;

a lower plurality of composite layers;

a first integral rib disposed between the upper plurality of composite layers and the lower plurality of composite layers, the first integral rib comprising a plurality of composite layers arranged in a stack, wherein at least one composite layer in the stack is wider than an adjacent composite layer in the stack; and

a second integral rib disposed between the upper plurality of composite layers and the lower plurality of composite layers, the second integral rib comprising a plurality of composite layers arranged in a stack, wherein at least one composite layer in the stack is wider than an adjacent composite layer in the stack.

15. A golf club head as defined in claim 14, wherein the first integral rib extends from a front perimeter of the crown portion to a rear perimeter of the crown portion.
