Abstract: A golf ball with one or more cover layers having an outer surface defining a plurality of dimples, one or more spherical core layers and one or more mantle layers superposed about the core layer. Each of the cover, core and mantle layers has a flexural modulus range of values. A particulate material layer is disposed onto the surface of one or more of the cover layer(s), the core layer(s) and the mantle layer(s). The particulate materials are comprised of a mixture of at least one from the group including metal, polymer, rubber, ceramic, and composite materials along with at least one adhesive compound. The particulate material layer(s) provide perimeter weighting for the golf ball layer onto which they are disposed. The particulate material layers(s) are formulated to have flexural moduli values that transition between the flexural moduli values of the golf ball layers between which the particulate material layer(s) are positioned.

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.
