Claims (16)

1. A golf ball, comprising:

a core layer;

an intermediate layer; and

a cover layer, wherein the intermediate layer is 100 wt. % poly(p-phenylene-2,6-benzobisoxazole), and wherein the intermediate layer is spun yarn or wound fiber up to 0.140 inches thick.

2. The golf ball of claim 1 , wherein the intermediate layer is a casing layer.

3. The golf ball of claim 1 , wherein at least one of the core layer or the cover layer includes a poly(p-phenylene-2,6-benzobisoxazole)-based material.

4. The golf ball of claim 1 , wherein the poly(p-phenylene-2,6-benzobisoxazole) is wound around the core layer and heat treated.

5. A golf ball comprising:

a dual core layer with an inner core layer and an outer core layer;

an intermediate layer; and

a cover layer,

wherein the intermediate layer is 100 wt. % poly(p-phenylene-2,6-benzobisoxazole), and wherein the intermediate layer is a spun yarn or wound fiber up to 0.140 inches thick.

6. The golf ball of claim 5 , wherein the intermediate layer is a casing layer.

7. The golf ball of claim 5 , wherein at least one of the inner core layer, the outer core layer, or the cover layer includes a poly(p-phenylene-2,6-benzobisoxazole)-based material.

8. The golf ball of claim 7 , wherein the poly(p-phenylene-2,6-benzobisoxazole)-based material is a filler or reinforcing agent.

9. The gold ball of claim 5 , wherein the poly(p-phenylene-2,6-benzobisoxazole) is wound around the dual core and heat treated.
