GOLF CLUB HEAD AFT BODY CONSTRUCTION
An aft body of a golf club head and method of manufacturing the aft body is shown. The aft body has a composite crown and sole and separately formed skirt between the crown and sole. The method of manufacturing the aft body includes thermoforming the crown and sole and subsequently injection molding the skirt.
1 . An aft body of a golf club head comprising:
a crown portion;
a sole portion opposite said crown portion;
a bridge portion connecting said crown portion and said sole portion at a rear end of said aft body; and
a skirt portion formed between an outer perimeter portion of said crown portion and an outer perimeter portion of said sole portion,
wherein said crown portion and said sole portion are made of a composite material,
wherein said skirt portion is made of a polymer material,
wherein said crown portion, said sole portion, and said bridge portion are integrally formed,
wherein said outer perimeter portion of said crown portion comprises a first shoulder,
wherein said outer perimeter portion of said sole portion comprises a second shoulder, and
wherein said first shoulder and said second shoulder are embedded within said skirt portion.
2 . The aft body of a golf club head of claim 1 , wherein said first shoulder is spaced apart from said second shoulder by a predetermined distance.
3 . The aft body of a golf club head of claim 1 , further comprising a weight housing attached to said bridge portion and located within said skirt portion at said rear end of said aft body.
4 . The aft body of a golf club head of claim 3 , wherein said weight housing includes a recessed portion configured to receive a weight member, and
wherein said weight housing comprises a threaded bore configured to receive a threaded fastener to secure said weight member to said weight housing.
5 . The aft body of a golf club head of claim 1 , wherein said polymer material of said skirt portion comprises at least one of polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyethylenimine, or polyether ether ketone.
6 . The aft body of a golf club head of claim 1 , wherein said crown portion and said sole portion have a thickness between 0.3 mm and 1.0 mm.
7 . The aft body of a golf club head of claim 1 , wherein said sole portion has a thickness greater than said crown portion.
8 . The aft body of a golf club head of claim 7 , wherein said sole portion has a thickness between 0.8 mm and 1.2 mm and said crown portion has a thickness between 0.4 mm and 0.8 mm.
9 . An aft body of a golf club head comprising:
a crown portion;
a sole portion opposite said crown portion;
a bridge portion connecting said crown portion and said sole portion at a rear end of said aft body; and
a skirt portion formed between an outer perimeter portion of said crown portion and an outer perimeter portion of said sole portion,
wherein said crown portion and said sole portion are made of a composite material,
wherein said skirt portion is made of a polymer material, and
wherein said sole portion has a thickness greater than said crown portion.
10 . The aft body of a golf club head of claim 9 , wherein said sole portion has a thickness between 0.8 mm and 1.2 mm and said crown portion has a thickness between 0.4 mm and 0.8 mm.
11 . The aft body of a golf club head of claim 9 , wherein said polymer material of said skirt portion comprises at least one of polycarbonate, polysulfone, polyethersulfone, polyphenylsulfone, polyethylenimine, or polyether ether ketone.
12 . The aft body of a golf club head of claim 9 , wherein said crown portion and said sole portion have a thickness between 0.3 mm and 1.0 mm.
