Golf ball with a translucent layer comprising composite material
View Patent ↗A golf ball comprising an opaque core, a composite cover layer, an intermediate layer, and an outer cover layer is provided. The composite cover layer and outer cover layer are formed from a translucent polymeric matrix, and a fibrous material is embedded in the translucent polymeric matrix of the composite cover layer. In one version, the fibrous material comprises a woven or non-woven mat. In another version, the fibrous material comprises a shape memory alloy. In yet another version, the fibrous material comprises a ferromagnetic material and the metal material is subjected to induction heating to improve adhesion between adjacent ball layers.
1. A golf ball comprising:
an opaque core, a composite cover layer, an intermediate layer disposed between the core and the composite layer, and an outer cover layer surrounding the composite cover layer;
the composite cover layer and outer cover layer each comprising a translucent polymer, wherein a fibrous material is at least partially embedded in the translucent polymer of the composite cover layer so the fibrous material is visible to a person viewing the ball, and wherein the fibrous material comprises a fibrous mat.
2. The golf ball of claim 1 , wherein the fibrous mat is woven.
3. The golf bail of claim 1 , wherein the fibrous mat is non-woven.
4. A golf ball comprising:
an opaque core, a composite cover layer, an intermediate layer disposed between the core and the composite layer, and an outer cover layer surrounding the composite cover layer;
the composite cover layer and outer cover layer each comprising a translucent polymer, wherein a fibrous material is at least partially embedded in the translucent polymer of the composite cover layer so the fibrous material is visible to a person viewing the ball, and wherein the fibrous material comprises a shape memory alloy.
5. The golf ball of claim 4 , wherein the shape memory alloy is selected from the group consisting of Ag—Cd, Cu—Al—Ni, Cu—Sn, Cu—Zn, Cu—Z—X (X═Si, Sn, Al), In—Ti, Ni—Al, Ni—Ti, Fe—Pt, Mn—Cu and Fe—Mn—Si.
6. A golf ball comprising:
an opaque core, a composite cover layer, an intermediate layer disposed between the core and the composite layer, and an outer cover layer surrounding the composite cover layer;
the composite cover layer and outer cover layer each comprising a translucent polymer, wherein a fibrous material is at least partially embedded in the translucent polymer of the composite cover layer so the fibrous material is visible to a person viewing the ball, and wherein the fibrous material comprises a ferromagnetic material.
7. The golf ball of claim 6 , wherein the ferromagnetic material is selected from the group consisting of Co 2 Ba 2 Fe 12 O 22 , Fe 3 O 4 (44 micron), Fe 3 O 4 (840 micron), Fe 2 O 3 , SrFe 12 O 19 , iron, cobalt, nickel, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, actinium, thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, iron based steel stocks, and pre-hardened steel stocks.
8. The golf ball of claim 7 , wherein the ferromagnetic material is subjected to induction heating.
