摘要:
A high CoR golf ball having predetermined moment of inertia is provided. A portion of the golf ball preferably contains substantially no filler, which contributes to the increased resilience of the ball. In accordance to one aspect of the invention, the portion with substantially no filler is an intermediate layer of the ball, and preferably is the outer core layer of the ball. The remaining portions of the ball preferably contribute to the moment of inertia of the ball. To craft a low moment of inertia ball, the innermost core should have a high specific gravity. Additionally, the outermost layers of the ball may have a low specific gravity. Conversely, to craft a high moment of inertia ball, the ball should have a thin dense layer positioned radially outward from its centroid radius. Additionally, the innermost core may have a low specific gravity. To craft a mid range moment of inertia ball, the ball may comprise a high specific gravity inner core and a thin dense layer. Preferably, the portion with substantially no filler is relatively larger than other portions of the ball.

The present invention is directed to multi-layer golf balls having a center, a cover layer, and at least one intermediate layer between the core and the cover layer. The center, the at least one intermediate layer and the cover are constructed to have different initial velocities and COR such that the gradients of initial velocities and COR progress from a slower center to a faster cover.

The present invention is directed to golf balls having a resilient inner core and outer core made of a material substantially free of fillers. The invention also encompasses golf balls wherein the inner and outer cores are not made of a thermoplastic material. The invention encompasses golf balls having an inner core, an outer core, an inner cover, and an outer cover wherein the inner core is encased by an outer core wherein the outer core has a volume greater than the inner core, inner cover, or outer cover and the inner core is made of a material substantially free of fillers. The volume relationship of the inner core (V12), outer core (V14), inner cover (V16), and outer cover (V18) is represented by the mathematical relationship: V14>⅗(V12+V16+V18), wherein V12≧V18≧V16. Also, the inner core has a specific gravity ρ12, the outer core has a specific gravity ρ14, the inner cover has a specific gravity ρ16, and the outer cover has a specific gravity ρ18, wherein the relationship between the specific gravities is expressed by the mathematical expression: ρ16≧ρ18≧ρ12≧ρ14.

摘要:
The present invention relates to golf ball components and golf balls comprising high levels of pre-vulcanized or pre-crosslinked materials, as well as methods of making same. The pre-vulcanized or pre-crosslinked materials are typically thermoset materials that are fragmented or ground into a powder, exposed to high pressure, high temperature sintering (“HPHTS”) and molded into the desired shape.

The present invention is directed towards a multi-layered core golf ball that comprises a thermoplastic inner casing layer molded between two polybutadiene core layers to create a faster golf ball with less spin, by designing a ball that has more of the stored energy of the core released at impact. One inner casing layer and/or an outer core layer is comprised of a partially or fully neutralized ionomer.
摘要:
A golf ball having a multi-layered core comprising at least three core layers and a dimpled cover is disclosed. The core may have three layers, A, B and C, four layers, A, B, C and D, five layers, A, B, C, D and E or up to six layers, A, B, C, D, E and F. In accordance to the present invention, the radius or thickness of each core layer is at least twice as much as the adjacent outer core layer. One outer core layer can be a water vapor barrier layer to protect the ball from water vapor encroachment, which reduces the performance of the ball. Another outer core layer can be a thin dense layer with high specific gravity to increase the rotational moment of inertia to reduce the spin of the ball during flight. Another outer core layer can be a perforated spherical shell to increase the resilience and/or coefficient of restitution of the ball. Another outer core layer could be a cushioning layer to act as a shock absorber. The core layers may also have increasing or decreasing hardness.
