Abstract

A method of manufacturing a component for a sole structure of an article of footwear includes providing a printer having a platform, a first head that receives a first feed, and a second head that receives a second feed. The method further includes printing a base layer on the platform, with the base layer comprising a substrate material and defining a longitudinal axis. Additionally, the method includes printing a first fiber layer continuously on the base layer, with the first fiber layer defining a first fiber orientation that is disposed at a first angle relative to the longitudinal axis, and printing a second fiber layer continuously on the first fiber layer, the second fiber layer defining a second fiber orientation that is disposed at a second angle relative to the longitudinal axis. The first angle is different from the second angle.

First claim

I claim:

1. A method of manufacturing a component for a sole structure of an article of footwear, the method comprising:
providing a three-dimensional printer having a platform, a first head that receives a first feed, and a second head that receives a second feed;
printing a base layer on the platform, the base layer comprising a substrate material and defining a longitudinal axis,
printing a first fiber layer continuously on the base layer, the first fiber layer defining a first fiber orientation that is disposed at a first angle relative to the longitudinal axis;
printing a second fiber layer continuously on the first fiber layer, the second fiber layer defining a second fiber orientation that is disposed at a second angle relative to the longitudinal axis, wherein the first angle is different from the second angle; and
treating a printed model in a compression molding process, wherein the printed model comprises at least the base layer, the first fiber layer, and the second fiber layer.

2. The method of claim 1 , wherein the first fiber layer comprises at least 60% of substrate material.

3. The method of claim 1 , wherein the second fiber layer comprises at least 50% of fiber material.

4. The method of claim 1 , wherein the first fiber layer and the second fiber layer define different layer volumes.

5. The method of claim 4 , wherein the first fiber layer includes at least one of a carbon fiber, an aramid fiber, a boron fiber, or a glass fiber.

6. The method of claim 1 , wherein the printed model comprises at least five fiber layers.

7. The method of claim 1 , wherein the printed model comprises an arch segment extending between a posterior segment and an anterior segment.

8. The method of claim 1 , wherein a transparent resin is applied to the printed model within the compression mold.

9. The method of claim 1 , wherein the printed model includes a third fiber layer defining a third fiber orientation that is disposed at a third angle relative to the longitudinal axis, the third angle being equal to the first angle and the third fiber layer being separated from the first fiber layer by the second fiber layer.

10. A plate for a sole structure of an article of footwear, the footwear comprising an upper having an insole, the plate comprising:
a medial side that is opposite a lateral side;
a heel end that is opposite a toe end;
a base layer comprising a substrate material; and
a plurality of composite layers coupled to the base layer, wherein each of the composite layers comprises a first volume of base material and a second volume of fiber material,
wherein the first volume of base material and the second volume of fiber material are different,
wherein each of the composite layers defines a fiber orientation, the fiber orientation being different between adjacent composite layers, and
wherein the plate is printed layer-by-layer to define a top side and a bottom side, at least a portion of the top side being spaced apart from the insole of the upper.

11. The plate of claim 10 , wherein the composite layers are arranged as a stack between a top side and bottom side of the plate and the stack has quasi-isotropic properties.

12. The plate of claim 11 , wherein each of the composite layers has anisotropic properties, the anisotropic properties being different between adjacent composite layers.

13. The plate of claim 12 , wherein the anisotropic properties include at least one of a bending resistance, a torsional resistance, or a tensile stiffness.

14. The plate of claim 10 , wherein the first volume of base material is less than the second volume of fiber material.

15. The plate of claim 10 , wherein the second volume of fiber material includes at least one of carbon fibers, aramid fibers, boron fibers, or glass fibers.

16. A method of using a three-dimensional printer and a compression mold for producing a plate for an article of footwear, comprising:
providing a feed of substrate material that is fed to a first head of the printer;
providing a feed of a fiber material that is fed to a second head of the printer;
providing a preformed model on a platform within the printer; and
providing a design model to the printer, wherein the first head and the second head are selectively activated and deactivated to print at least two composite layers on the preformed model, and
wherein the at least two composite layers are separated from the preformed model and received within the compression mold.

17. The method of claim 16 , wherein each of the at least two composite layers comprises a continuous fiber strand that is applied by the second head.

18. The method of claim 16 , wherein the plate includes an anterior segment having a first stiffness, an arch segment having a second stiffness, and a posterior segment having a third stiffness.

19. The method claim 18 , wherein the first stiffness is greater than the second stiffness and the third stiffness is greater than the first stiffness.

20. The method of claim 18 , wherein the first stiffness, the second stiffness, and the third stiffness are equal.
