Abstract

A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.

Claims

1. A golf club head comprising:

a metallic section including a face, wherein the metallic section defines an opening;

a polymeric section extending over the opening; and

an adhesive material disposed between the metallic section and the polymeric section such that the polymeric section is adhered to the metallic section to form an adhesive joint therebetween;

wherein the adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section;

wherein the metallic section and the polymeric section are physically engaged with one another to form a mechanical joint therebetween, wherein the mechanical joint has a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section; and

wherein the adhesive retaining strength of the adhesive joint is greater than the mechanical retaining strength of the mechanical joint.

6. The golf club head, as set forth in claim 1, wherein the adhesive material is configured to cure;

wherein the adhesive retaining strength of the adhesive joint is configured to be greater than the mechanical retaining strength of the mechanical joint when the adhesive material is at least partially cured; and

wherein the mechanical joint is operative to hold the polymeric section in attachment with the metallic section until the adhesive material is at least partially cured.

7. The golf club head, as set forth in claim 6, wherein the adhesive retaining strength is configured to be no greater than the mechanical retaining strength of the mechanical joint when the adhesive material is not at least partially cured.

8. The golf club head, as set forth in claim 1, wherein the mechanical joint is operative to mechanically align the polymeric section over the opening, relative to the metallic section.

9. The golf club head, as set forth in claim 1, the metallic section comprises a metallic material and the polymeric section comprises a polymeric material;

and

wherein the metallic material is selected from a group consisting of a titanium alloy, a steel alloy, stainless steel, and an amorphous metal alloy.

10. The golf club head, as set forth in claim 9, wherein the polymeric material comprises an injection molded polyamide.

11. The golf club head, as set forth in claim 1, wherein the metallic section and the polymeric section form an interference fit with one another such that the mechanical joint is formed therebetween.

12. The golf club head, as set forth in claim 1, wherein the metallic section and the polymeric section each include a retention feature configured to mechanically engage one another to form the mechanical joint therebetween.

13. A golf club head comprising:

a forward section including a face;

a body bonded to the forward section and including a first polymeric section and a second polymeric section;

an adhesive material disposed between a portion of the first polymeric section and the second polymeric section to form an adhesive joint therebetween;

wherein the adhesive joint has an adhesive retaining strength configured to inhibit the first polymeric section from being detached from the second polymeric section when the adhesive material is at least partially cured;

wherein the first polymeric section and the second polymeric section are mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the first polymeric section from being detached from the second polymeric section; and

wherein the adhesive retaining strength of the adhesive joint is greater than the mechanical retaining strength of the mechanical joint when the adhesive material is at least partially cured.

14. The golf club head, as set forth in claim 13, wherein the adhesive retaining strength is configured to be no greater than the mechanical retaining strength of the mechanical joint when the adhesive material is not at least partially cured.

18. The golf club head, as set forth in claim 13, wherein the first polymeric section and the second polymeric section each comprise an injection molded polyamide material.

19. The golf club head, as set forth in claim 13, wherein the forward section comprises a metallic material selected from a group consisting of a titanium alloy, a steel alloy, stainless steel, and an amorphous metal alloy.

20. The golf club head, as set forth in claim 13, wherein the first polymeric section and the second polymeric section each include a retention feature mechanically engaged with one another such that the mechanical joint is formed therebetween.
