초록 ▼

A method for manufacture of a hollow complex three-dimensional fiber golf club head having at least one hole. A fluid-removable core is shaped in the general form of the golf club head, placed in a flexible pressurizable bladder around the core, at least one ply of fiber impregnated with a curable resin is wrapped over the core and bladder, and a cured part is formed by pressurizing the bladder while the core, bladder, and impregnated fiber is in a female mold to force the plies against the inner surfaces of the mold. After heating to cure the resin, the bladder and the fluid-removable core is removed from the interior of the cured part by disintegrating core with a fluid sufficient to allow removal of the bladder.

대표청구항 ▼

1. A method for manufacture of a hollow complex three-dimensional fiber golf club head having at least one hole, the method comprising;placing a mandrel core comprising a solvent-soluble material in a pressurizable bladder to form a bladder/core assembly,wrapping resin impregnated reinforcing fiber around the bladder/core assembly,pressurizing the bladder in a female mold to compact the fiber against inside surfaces of the mold and heating the mold to cure the resin to form a cured part, such that compaction of the fiber against the inside surfaces of the mold is from the pressurization of the bladder and not from the mandrel core,removing the mandrel core and bladder from the interior of the cured part by injecting solvent into the interior of the bladder to disintegrate and remove sufficient core material to allow removal of the bladder from the interior of the cured part. 2. The method of claim 1 wherein the solvent comprises water and the core comprises a water-soluble material. 3. The method of claim 1 wherein the bladder comprises a water-soluble material which is at least partially solubilized when the water is introduced into the interior of the bladder. 4. The method of claim 1 wherein the bladder is in part removed by dissolving the water soluble material of the bladder when the solvent is introduced into the interior of the bladder. 5. The method of claim 1 wherein the bladder is removed by pulling the bladder out through a hole in the cured part. 6. A method for manufacture of a hollow complex three-dimensional fiber golf club head having at least one hole, the method comprising;shaping a meltable core in the general form of the golf club head,placing a flexible pressurizable bladder around the core,wrapping over the assembly of core and bladder at least one ply of fiber impregnated with a curable resin,forming a cured part by pressurizing the bladder while the assembly of core, bladder, and impregnated fiber is in a mold to force the plies against the inner surfaces of the mold, such that compaction of the fiber against the inner surfaces of the mold is from the pressurization of the bladder and not from the core, and heating to cure the resinremoving the bladder and the meltable core from the interior of the cured part by first melting and removing core sufficient to allow removal of the bladder. 7. The method of claim 6 wherein the core comprises a metal alloy. 8. A method for manufacture of a hollow complex three-dimensional fiber golf club head having at least one hole, the method comprising;shaping a fluid-removable core in the general form of the golf club head,placing a flexible pressurizable bladder around the core,wrapping over the assembly of core and bladder at least one ply of fiber impregnated with a curable resin,forming a cured part by pressurizing the bladder while the assembly of core, bladder, and impregnated fiber is in a female mold to force the plies against the inner surfaces of the mold, such that compaction of the fiber against the inner surfaces of the mold is essentially from the pressurization of the bladder and not from the core, and heating to cure the resin,removing the bladder and the fluid-removable core from the interior of the cured part by first disintegrating and removing at least a portion of the fluid-removable core with a fluid sufficient to allow removal of the bladder. 9. The method of claim 8 wherein the fluid-removable core comprises a material that is soluble in the fluid. 10. The method of claim 8 wherein the fluid-removable core comprises a water soluble starch and the fluid comprises water. 11. The method of claim 8 wherein the fluid comprises water. 12. The method of claim 8 wherein the bladder is formed by heat sealing a heat-sealable film, by molding, or by dipping and curing around a mandrel. 13. The method of claim 8 wherein the core includes structure corresponding to the hosel of the head and an inflation fitting is disposed relative to said structure whereby the inflation fitting is used to pressurize the bladder. 14. The method of claim 8 wherein when the inflation fitting is removed it leaves a hole into the interior of the cured part through which fluid is introduced into the interior of the part for the disintegrating and removing the portion of the fluid removable core. 15. The method of claim 8 wherein the bladder comprises a fluid-removable material. 16. The method of claim 15 wherein the fluid removable bladder material comprises a water soluble material and the fluid removable core comprises a water-soluble material. 17. The method of claim 16 wherein the fluid is water, and the removing of the bladder and core comprises injecting water into the interior of the part to dissolve and remove the fluid removable bladder material and the fluid removable core. 18. The method of claim 17 wherein undissolved portions of the fluid removable core material and the fluid soluble bladder material are removed by the injecting of the water.
