Abstract
A golf ball is provided that has a spherical core exhibiting a stiffness from 400 MPa to 200 GPa. The stiffness of the core may be controlled by adjusting the materials of construction and the ratio of the materials. 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 golf ball that has less hook and slice during play.
Claims11
A golf ball comprising:
- a cover layer having an outer surface defining a plurality of dimples and an inner surface opposite the outer surface that defines a cavity;
- and
- a spherical core disposed within the cavity, wherein the spherical core comprises a polymer matrix composite and has a stiffness from 400 MPa to 200 GPa, and wherein the polymer matrix composite comprises a polymer resin and silicon carbide whiskers.
