Composite plate for an article of footwear
A stitched article includes a substrate and a first strand portion formed from a bundle of fibers. The substrate has a first region and a second region. The first strand portion is attached to the substrate in the first region and in the second region via a series of stitches formed with a thread and forms a first layer on the substrate. The article has a first concentration of the stitches in the first region along a first length of the strand portion and a second concentration of the stitches different than the first concentration in the second region along a second length of the first strand portion.
1. A method for forming a plate for an article of footwear, the method comprising:
forming a stitched article including:
providing a substrate with a first region and a second region; and
attaching a first strand portion formed from a first bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a first thread by crossing the stitches over the first strand portion and penetrating the substrate at first attachment locations that are spaced apart from the first strand portion to form a first layer on the substrate, the stitched article having a first concentration of the stitches in the first region along a first length of the first strand portion and a second concentration of the stitches different than the first concentration in the second region along a second length of the first strand portion.
2. The method of claim 1 , further comprising consolidating at least one of (i) fibers of at least the first bundle of fibers of the first strand portion, (ii) fibers and/or a yarn of the substrate, and (iii) the first thread of the stitched article with a resin composition.
3. The method of claim 1 , further comprising extending the first length of the first strand portion in a direction between a medial side of the substrate and a lateral side of the substrate.
4. The method of claim 3 , further comprising extending the second length of the first strand portion in a direction between the medial side of the substrate and the lateral side of the substrate.
5. The method of claim 1 , wherein the first concentration is greater than the second concentration.
6. The method of claim 1 , further comprising providing a first average distance between stitches in the first region that is greater than a second average distance between stitches in the second region.
7. The method of claim 1 , wherein attaching the first strand portion formed from the first bundle of fibers to the substrate includes attaching a first bundle of fibers including at least one of carbon fibers, boron fibers, glass fibers, and synthetic polymer fibers.
8. The method of claim 1 , wherein forming the stitched article includes attaching a second strand portion formed from a second bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a second thread.
9. The method of claim 8 , wherein attaching the first strand portion formed from the first bundle of fibers to the substrate includes attaching a first bundle of fibers including carbon fiber, and attaching the second strand portion formed from the second bundle of fibers to the substrate includes attaching a second bundle of fibers including glass fibers.
10. The method of claim 1 , further comprising attaching a plurality of traction elements to a side of the plate.
11. A method for forming a plate for an article of footwear, the method comprising:
forming a stitched article including:
providing a substrate with a first region and a second region;
extending a first length of a first strand portion formed from a first bundle of fibers in a direction between a medial side of the substrate and a lateral side of the substrate; and
attaching the first strand portion to the substrate in the first region and in the second region via a series of stitches formed with a first thread to form a first layer on the substrate, the stitched article having a first concentration of the stitches in the first region along the first length of the first strand portion and a second concentration of the stitches different than the first concentration in the second region along a second length of the first strand portion.
12. The method of claim 11 , further comprising extending the second length of the first strand portion in a direction between the medial side of the substrate and the lateral side of the substrate.
13. The method of claim 11 , wherein the first concentration is greater than the second concentration.
14. A method for forming a plate for an article of footwear, the method comprising:
forming a stitched article including:
providing a substrate with a first region and a second region; and
attaching a first strand portion formed from a first bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a first thread to form a first layer on the substrate, the stitched article having a first concentration of the stitches in the first region along a first length of the first strand portion and a second concentration of the stitches less than the first concentration in the second region along a second length of the first strand portion.
15. The method of claim 14 , wherein attaching the first strand portion formed from the first bundle of fibers to the substrate includes attaching a first bundle of fibers including at least one of carbon fibers, boron fibers, glass fibers, and synthetic polymer fibers.
16. The method of claim 14 , wherein forming the stitched article includes attaching a second strand portion formed from a second bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a second thread.
17. Method for forming a plate for an article of footwear, the method comprising:
forming a stitched article including:
providing a substrate with a first region and a second region; and
attaching a first strand portion formed from a first bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a first thread to form a first layer on the substrate, the stitched article having a first average distance between the stitches in the first region along a first length of the first strand portion and a second average distance between the stitches that is less than the first average distance in the second region along a second length of the first strand portion.
18. The method of claim 17 , wherein attaching the first strand portion formed from the first bundle of fibers to the substrate includes attaching a first bundle of fibers including at least one of carbon fibers, boron fibers, glass fibers, and synthetic polymer fibers.
19. The method of claim 17 , wherein forming the stitched article includes attaching a second strand portion formed from a second bundle of fibers to the substrate in the first region and in the second region via a series of stitches formed with a second thread.
