Abstract
The invention includes a golf ball having a center, a hoop-stress layer of high tensile elastic modulus material wrapped or wound about the core, at least one layer of a resilient elastomeric material, and a cover of at least one layer. The center in the golf ball can be a fluid with an encapsulating shell or a solid. A binding material can be used in conjunction with the hoop-stress layer to facilitate positioning of the hoop-stress layer around the center for easier manufacturing.
Claims41
A golf ball comprising four or more layers, wherein one of the layers is a hoop-stress layer, comprising at least one material with a tensile elastic modulus of at least about 10,000 kpsi, situated between two of the three innermost layers.
A golf ball having four or more layers comprising:
- a center;
- a cover comprising at least one layer;
- and
- a hoop-stress layer comprising at least one material with a tensile elastic modulus of at least about 10,000 kpsi, situated between two of the three innermost layers, wherein the material has a first cross-sectional area and the material is coated with a binding material to provide a coated material with a second cross-sectional area greater than the first.
