Abstract

A golf ball with aerodynamic coefficient magnitude and aerodynamic force angle, resulting in improved flight performance, such as increased carry and flight consistency regardless of ball orientation. In particular, the present invention is directed to a golf ball having increased flight distance as defined by a set of aerodynamic requirements, at particular spin ratios and Reynolds Numbers. The invention is also directed toward golf balls having high spin decay rates during the first second of flight that yields improved flight performance and longer ball flight.

Claims (17)

1. A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a fluid and a honeycomb material, such that after being impacted by a golf club the rate of spin decay is greater than 4% during the first second after impact.

2. The golf ball of claim 1 , wherein the honeycomb material comprises polycarbonate.

3. The golf ball of claim 1 , wherein the honeycomb material comprises polypropylene.

4. The golf ball of claim 1 , wherein the intermediate layer decouples the solid core from the solid cover.

5. The golf ball of claim 1 , wherein the fluid has a viscosity of from about 1,000 to about 250,000 centipoises.

6. The golf ball of claim 1 , wherein the intermediate layer comprises a viscoelastic liquid.

7. A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a fluid and a honeycomb material, wherein the fluid has a viscosity of from about 1,000 to about 250,000 centipoises.

8. The golf ball of claim 7 , wherein the honeycomb material comprises polycarbonate.

9. The golf ball of claim 7 , wherein the honeycomb material comprises polypropylene.

10. The golf ball of claim 7 , wherein the fluid has a viscosity of from about 10,000 to about 250,000 centipoises.

11. The golf ball of claim 7 , wherein the fluid has a viscosity of from about 50,000 to about 250,000 centipoises.

12. The golf ball of claim 7 , wherein the fluid has a viscosity of from about 100,000 to about 250,000 centipoises.

13. A golf ball comprising a solid core, a solid cover and an intermediate layer disposed therebetween, wherein the intermediate layer comprises a viscous fluid and a honeycomb material, wherein the specific gravities of the viscous fluid and the core are within about 3% of each other.

14. The golf ball of claim 13 , wherein the honeycomb material comprises polycarbonate.

15. The golf ball of claim 13 , wherein the honeycomb material comprises polypropylene.

16. The golf ball of claim 13 , wherein the specific gravities of the viscous fluid and the core are within about 2% of each other.

17. The golf ball of claim 13 , wherein the specific gravities of the viscous fluid and the core are within about 1% of each other.
