Abstract

A golf ball with a mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the mantle layer is disclosed herein. The golf ball may multiple layers. A preferred embodiment of a golf ball comprises a core, a mantle layer and a cover.

Claims (16)

1. A golf ball comprising:

a core;

a mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the mantle layer; and

a cover layer disposed over the mantle layer.

2. The golf ball according to claim 1 wherein the graphene material ranges from 0.4 to 2.5 weight percent of the mantle layer.

3. The golf ball according to claim 1 wherein the graphene material ranges from 0.6 to 1.5 weight percent of the mantle layer.

4. A golf ball comprising:

a core;

an inner mantle layer disposed over the core, the inner mantle layer having a thickness ranging from 0.03 inch to 0.09 inch, the inner mantle layer composed of an ionomer material, the inner mantle layer material having a plaque Shore D hardness ranging from 34 to 55;

an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.050 inch, the outer mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the outer mantle layer; and

a cover layer disposed over the outer mantle layer, the cover layer has a thickness ranging from 0.025 inch to 0.040 inch.

5. A golf ball comprising:

a core;

an inner mantle layer disposed over the core, the inner mantle layer having a thickness ranging from 0.030 inch to 0.090 inch, the inner mantle layer comprising an ionomer material and a graphene material in an amount ranging from 0.1 to 5.0 weight percent of the inner mantle layer;

an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.070 inch, the outer mantle layer material having a plaque Shore D hardness ranging from 50 to 71, wherein the inner mantle is thicker than the outer mantle, and the outer mantle is harder than the inner mantle; and

a cover layer is disposed over the outer mantle layer, the cover layer having a thickness ranging from 0.025 inch to 0.050 inch.
