Abstract

A golf club head includes a first portion joined to a second portion to at least partially define an interior club head volume. The first portion includes a wall defining an outer boundary of the club head volume, and a support rib extending from the wall to operatively stiffen the first portion. The second portion of the golf club head can engage the support rib, and the support rib can be adhered to the second portion to join the first portion and the second portion.

First claim

The invention claimed is:

1. A golf club head comprising:
a first portion joined to a second portion to at least partially define an interior club head volume;
wherein the first portion includes:
a wall defining an outer boundary of a club head volume; and
a support rib extending from the wall to operatively stiffen the first portion;

wherein the second portion of the golf club head engages a portion of the support rib of the first portion; and
wherein the second portion comprises a polymeric material comprising a resin and a plurality of discontinuous fibers.

2. The golf club head of claim 1 , wherein the plurality of discontinuous fibers have lengths from 3 mm to 12 mm.

3. The golf club head of claim 1 , wherein the plurality of discontinuous fibers have lengths from 0.01 mm to 3 mm.

4. The golf club head of claim 1 , wherein the polymeric material has a resin content from about 40% to about 90% by weight.

5. The golf club head of claim 4 , wherein the polymeric material has a resin content from about 55% to about 70% by weight.

6. The golf club head of claim 1 , wherein the plurality of discontinuous fibers are discontinuous chopped carbon fibers.

7. The golf club head of claim 1 , wherein the first portion and the second portion further define a lap joint therebetween; and wherein the first portion is adhered to the second portion across the lap joint.

8. The golf club head of claim 7 , wherein the lap joint comprises a plurality of embossed spacing features across a surface of the lap joint.

9. The golf club head of claim 8 , wherein the plurality of embossed spacing features protrude above the surface by about 0.05 mm to about 0.50 mm.

10. The golf club head of claim 1 , further comprising a weight that is removably secured to one of the first portion and the second portion.

11. A golf club head comprising:
a first portion joined to a second portion to at least partially define an interior club head volume; wherein:
the first portion includes a wall defining an outer boundary of a club head volume;
the first portion includes a support rib extending from the wall to operatively stiffen the first portion; and
the second portion comprises a polymeric material comprising a resin and a plurality of discontinuous fibers.

12. The golf club head of claim 11 , wherein the plurality of discontinuous fibers have lengths from 3 mm to 12 mm.

13. The golf club head of claim 11 , wherein the plurality of discontinuous fibers have lengths from 0.01 mm to 3 mm.

14. The golf club head of claim 11 , wherein the polymeric material has a resin content from about 40% to about 90% by weight.

15. The golf club head of claim 14 , wherein the polymeric material has a resin content from about 55% to about 70% by weight.

16. The golf club head of claim 11 , wherein the plurality of discontinuous fibers are discontinuous chopped carbon fibers.

17. The golf club head of claim 11 , wherein the first portion and the second portion further define a lap joint therebetween; and wherein the first portion is adhered to the second portion across the lap joint.

18. The golf club head of claim 17 , wherein the lap joint comprises a plurality of embossed spacing features across a surface of the lap joint.

19. The golf club head of claim 18 , wherein the plurality of embossed spacing features protrude above the surface by about 0.05 mm to about 0.50 mm.

20. The golf club head of claim 11 , further comprising a weight that is removably secured to one of the first portion and the second portion.
