Golf ball with a translucent layer comprising composite material
View Patent ↗A golf ball having at least a core and a composite layer comprising a fibrous material and a matrix material is disclosed. The fibrous material may comprise a polymer, glass or metal. The matrix material preferably comprises a translucent polymer. In one embodiment of the present invention, the fibrous material comprises a ferromagnetic material and the golf ball is subjected to induction heating to improve adhesion between adjacent ball layers. The golf ball may additionally comprise a translucent cover layer surrounding the composite layer or an intermediate layer disposed between the composite layer and the core.
1. A golf ball comprising an opaque core and a composite cover layer and an inteiniediate layer disposed between the core and the composite layer and an outer cover layer surrounding the composite cover layer, the outer cover layer comprising a translucent polymer;
wherein at least a portion of said composite cover layer comprises a translucent polymer, and
wherein a fibrous material is at least partially embedded in said translucent polymer of said composite cover layer so the fibrous material is visible to a person viewing the ball, and
wherein said fibrous material comprises at least one material selected from the group consisting of polymers, ceramic glass, and metal.
2. The golf ball of claim 1 , wherein said fibrous material comprises individual fibers having a length between about 0.5 mm and about 10.0 mm.
3. The golf ball of claim 1 , wherein said fibrous material comprises a filament.
4. The golf ball of claim 1 , wherein said fibrous material has an aspect ratio of about 5 or greater.
5. The golf ball of claim 1 , wherein said fibrous material comprises at least one material selected from the group consisting of polyether urea, poly(ester-urea), polyester block copolymers, poly(propylene), polyethylene, polyamide, acrylics, polyketone, poly(ethylene terephthalate), poly(phenylene terephthalate), poly(acrylonitrile), trans-diaminodicyclohexylmethane, dodecanedicarboxylic acid and poly(trimethylene terephthalate).
6. The golf ball of claim 1 , wherein said intermediate layer comprises at least one polymer.
7. The golf ball of claim 6 , wherein said polymer is selected from the group consisting of polybutadiene, natural rubber, polyisoprene, styrene-butadiene, ethylene- propylene-diene rubber and highly neutralized polymers.
8. The golf ball of claim 1 , wherein said intermediate layer comprises elastic fibers wound around said core.
9. The golf ball of claim 1 , wherein said composite layer further comprises an amount of reflective particulates.
10. The golf ball of claim 9 , wherein said reflective particulates have an aspect ratio of at least about 5 and are selected from the group consisting of metal flake, iridescent glitter, metalized film and colored polyester foil.
