    Abstract: A multi-layer golf ball includes a core, an intermediate layer surrounding the core, and a cover layer surrounding the intermediate layer. The core defines an outer surface that includes a plurality of polygonal land portions substantially aligned on a common sphere, which has a diameter of between 22 mm and 32 mm. The intermediate layer has a radially inward-facing surface that is flush with the outer surface of the core, and has a radial thickness of between 4 mm and 9 mm. The outer surface of the core defines a first set of annular grooves disposed about a first axis, and a second set of annular grooves disposed about a second axis. Each of the first and second set of annular grooves extend radially inward from the common sphere, and the first axis and the second axis are orthogonal.

    Abstract: A thermoplastic multi-layer golf ball has a core center having a shell from about 1-6 mm thick defining an interior space about 12-24 mm in diameter, a core layer at least about 5 mm thick outward from the core center, and a cover. The shell includes a first thermoplastic material with first flexural modulus less than about 15,000 psi. The core layer includes a second thermoplastic material with second flexural modulus up to about 15,000 psi and greater than the first flexural modulus and a specific gravity of at least about 1.5 g/cm3. The cover includes a third thermoplastic material with a third flexural modulus that in a first embodiment is up to about 5,000 psi and less than the first flexural modulus and in a second embodiment is least about 40,000 psi.

    Abstract: A golf ball is provided that includes at least one layer of material that is a composite of thermoplastic and a second phase material that is dispersed within the thermoplastic. This material may be a blend of thermoplastic and elastomeric material. Preferably, the golf ball comprises a hard sphere core such as a hollow metal core, a layer of Thermoplastic Elastomer Composite, and a cover layer. This results in a golf ball that is legal for play and capable of drive distances essentially equivalent to those of currently available high performance golf balls, but also provides a ball that has less hook and slice during play, while being durable and economical to produce.
