1. A golf club head comprising:
a body comprising a face, a crown, a sole, a toe, a heel, a cavity, a hosel, and a shaft, wherein the cavity comprises an outer shell and a filler material, wherein the cavity has a rounded bottom,
wherein the filler material has a glass transition temperature, and wherein the hosel is adjustable within the cavity when the filler material reaches the glass transition temperature.
2. The golf club head of claim 1 , wherein the filler material is a thermoplastic material.
3. The golf club head of claim 1 , wherein the glass transition temperature is about 130° F. or higher.
4. The golf club head of claim 3 , wherein the glass transition temperature is about 140° F. or higher.
5. The golf club head of claim 1 , wherein the golf club head has a face angle that is adjustable by about 10° or less from a square alignment.
6. The golf club head of claim 1 , wherein the golf club head has a lie angle that is adjustable by about 20 percent in either direction.
7. The golf club head of claim 1 , wherein the golf club head has a loft angle that is adjustable by about 5° or less from the preset loft angle.
8. The golf club head of claim 1 , wherein the filler material comprises polyurethane, polyurea, epoxy, elastomer, polyethylene, polyamides, ionomer, polyesters, polypropylene, or combinations thereof.
9. The golf club head of claim 8 , wherein the filler material is selected from the group consisting of polyurethane, polyurea, or a combination thereof.
10. The golf club head of claim 1 , wherein the cavity extends less than 75 percent of the distance from the crown to the sole.
11. The golf club head of claim 1 , wherein the cavity extends less than about 90 percent of a distance from the crown to the sole.
12. A golf club head comprising:
a body comprising a face, a crown, a sole, a toe, a heel, a hosel disposed within a cavity, and a shaft, wherein the cavity comprises an outer shell with a rounded bottom and a filler material disposed within the outer shell selected from the group consisting of polyurethane, polyurea, or a combination thereof,
wherein the filler material has a glass transition temperature of about 130° F. or higher, and wherein the hosel is adjustable within the cavity when the filler material reaches the glass transition temperature.
13. The golf club head of claim 12 , wherein the glass transition temperature is about 150° F. or higher.
14. The golf club head of claim 12 , wherein the glass transition temperature ranges from about 130° F. to about 275° F.
15. The golf club head of claim 12 , wherein the filler material has a specific gravity of less than about 1.5.
16. The golf club head of claim 12 , wherein the adjustable hosel allows adjustability of lie angle, face angle, loft angle, or combinations thereof.
17. The golf club head of claim 16 , wherein the lie angle is adjustable between about 40° and 70°, the face angle is adjustable by at least about 5° from a square alignment, and the loft angle is adjustable by about 10° or less from a preset loft angle.
18. The golf club head of claim 12 , wherein the cavity extends less than about 90 percent of a distance from the crown to the sole.
