Abstract
The present invention is directed to a golf ball comprising a multi-layer core component. The multi-layer core comprises an interior center component formed from a thermoset material, a thermoplastic material, or combinations thereof. The multi-layer core also comprises a core layer disposed about the center component, formed from a thermoset material, a thermoplastic material, or combinations thereof. The present invention golf ball may further comprise an outer core layer that surrounds the multi-layer core. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known golf balls.
Claims20
A golf ball comprising:
- a multi-layer core comprising a center component and a core layer disposed about said center component;
- wherein said center component comprises a thermoset material and said core layer comprises a thermoset material;
- and,
- a cover layer disposed about said multi-layer core;
- wherein said cover layer includes at least one of (i) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less, said inner cover layer being harder than said outer cover layer, (ii) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater, wherein said inner cover layer is softer than said outer cover layer, (iii) a single non-ionomeric outer cover layer having a Shore D hardness of from about 40 to 80, and (iv) a single ionomeric outer cover layer having a Shore D hardness of at least 56.
A golf ball comprising:
- a multi-layer core comprising a center component and a core layer disposed about said center component;
- wherein said center component comprises a polybutadiene thermoset material and said core layer comprises a polybutadiene thermoset material;
- and,
- a cover layer disposed about said multi-layer core;
- wherein said cover layer includes at least one of (i) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less, said inner cover layer being harder than said outer cover layer, (ii) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater, wherein said inner cover layer is softer than said outer cover layer, and (iii) a single non-ionomeric outer cover layer having a Shore D hardness of from about 40 to 80, and (iv) a single ionomeric outer cover layer having a Shore D hardness of at least 56.
A golf ball comprising:
- a multi-layer core comprising a center component and a core layer disposed about said center component;
- wherein said center component comprises a polybutadiene/ZDA thermoset material and said core layer comprises a polybutadiene/ZDA thermoset material;
- and,
- a multi-layer, ionomeric cover layer disposed about said dual core;
- wherein said cover layer includes at least one of (i) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less, said inner cover layer being harder than said outer cover layer, and (ii) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater, wherein said inner cover layer is softer than said outer cover layer.
