Abstract

A method of making a tire includes forming a first sheet of material having a circular shape. The first sheet of material includes an upper ring and a lower ring. The first sheet of material further includes a plurality of spoke portions extending from the upper ring to the lower ring. A reinforcement is placed on the first of polymeric material, which includes placing the reinforcement on at least a portion of the upper ring. A second sheet of material having a circular shape is formed. The second sheet of material is placed on the first sheet of material such that the reinforcement is sandwiched between the first and second sheets of material. The method further includes placing additional sheets of material and additional reinforcements on the second sheet of material until a tire is built.

First claim

What is claimed is:

1. A method of making a tire, the method comprising:
forming a first sheet of polymeric material having a substantially circular shape,
wherein the first sheet of polymeric material includes a first upper ring and a first lower ring, and
wherein the first sheet of polymeric material further includes a first plurality of spoke portions extending from the first upper ring to the first lower ring;
placing a reinforcement on the first sheet of polymeric material, including placing the reinforcement on at least a portion of the first upper ring;
forming a second sheet of polymeric material having a substantially circular shape;
placing the second sheet of polymeric material on the first sheet of polymeric material such that the reinforcement is sandwiched between the first sheet of polymeric material and the second sheet of polymeric material;
placing additional sheets of polymeric material having substantially circular shapes and placing additional reinforcements on the second sheet of polymeric material, until a tire is built having a predetermined width; and
wherein the placing the reinforcement on the first sheet of polymeric material includes placing cords of material on the first sheet of polymeric material.

2. The method of claim 1 , further comprising curing the tire.

3. The method of claim 1 , wherein the forming the first sheet of polymeric material having a substantially circular shape includes forming the first sheet of polymeric material by an additive manufacturing method.

4. The method of claim 3 , wherein the additive manufacturing method is selected from the group consisting of 3D printing, binder jetting, directed energy deposition, fused deposition modeling, laser sintering, material jetting, material extrusion, powder bed fusion, rapid prototyping, rapid tooling, sheet lamination, and vat photopolymerization.

5. The method of claim 1 , wherein the forming the first sheet of polymeric material having a substantially circular shape includes forming the first sheet of polymeric material by a subtractive manufacturing method.

6. The method of claim 1 , wherein the forming the first sheet of polymeric material having a substantially circular shape includes molding the first sheet of polymeric material.

7. The method of claim 1 , wherein the placing the reinforcement on the first sheet of polymeric material includes placing the reinforcement on at least some of the first plurality of spoke portions.

8. The method of claim 1 , wherein the placing the reinforcement on the first sheet of polymeric material is performed by a 3D printing process.

9. The method of claim 1 , wherein the forming the first sheet of polymeric material includes forming a first polymeric sheet of a first polymeric material and a first metal.

10. The method of claim 1 , further comprising placing an electronic device on the first sheet of polymeric material, prior to placing the second sheet of polymeric material on the first sheet of polymeric material, such that the electronic device is sandwiched between the first sheet of polymeric material and the second sheet of polymeric material.

11. The method of claim 1 , wherein the reinforcement includes at least one upper ring and a plurality of spoke reinforcements extending from the at least one upper ring, and wherein the placing the reinforcement on the first sheet of polymeric material includes placing the at least one upper ring and the plurality of spoke reinforcements on the first sheet of polymeric material, the plurality of spoke reinforcements being spaced circumferentially from one another.

12. The method of claim 1 , wherein the reinforcement includes at least one upper ring and at least one lower ring spaced apart from and below the at least one upper ring, and wherein the placing the reinforcement on the first sheet of polymeric material includes placing the at least one upper ring and the at least one lower ring on the first sheet of polymeric material.

13. A method of making a green tire, the method comprising:
forming a plurality of sheets of green rubber having a substantially circular shape,
wherein each sheet of green rubber includes an upper ring and a lower ring, and
wherein each sheet of green rubber further includes a plurality of spoke portions extending from the upper ring to the lower ring;
forming a plurality of reinforcements;
disposing each reinforcement of the plurality of reinforcements between adjacent sheets of the plurality of sheets of green rubber, wherein at least one reinforcement is sandwiched between the upper rings of adjacent sheets of green rubber; and
wherein the forming the plurality of reinforcements includes forming the plurality of reinforcements from cords of material.

14. The method of claim 13 , wherein the disposing each reinforcement of the plurality of reinforcements between adjacent sheets of the plurality of sheets of green rubber includes sandwiching at least one reinforcement between the spoke portions of adjacent sheets of green rubber.

15. The method of claim 13 , wherein the disposing each reinforcement of the plurality of reinforcements between adjacent sheets of the plurality of sheets of green rubber includes sandwiching at least one reinforcement between the lower rings of adjacent sheets of green rubber.

16. The method of claim 13 , wherein the forming the plurality of sheets of green rubber includes forming the plurality of sheets of green rubber from a plurality of different green rubber compounds.

17. The method of claim 13 , wherein the forming the plurality of sheets of green rubber includes forming the plurality of spoke portions with a geometry that varies along an axial direction of the green tire.

18. The method of claim 13 , wherein the forming the plurality of sheets of green rubber includes forming the plurality of sheets of green rubber with a thickness between 0.02 mm to 25.4 mm.
