Abstract

Embodiments relate generally to a traction surface and methods for forming the traction surface. The traction surface may comprise a compound material comprising glass fibers oriented orthogonal to the surface of the compound material extending from the compound material, wherein when the traction surface contacts an icy surface, the glass fibers are operable to penetrate a liquid-like top layer of the icy surface to provide grip with an ice layer below the liquid-like top layer. The method for forming the traction surface may comprise integrating glass fibers into a compound material; orienting the glass fibers within the compound material such that the glass fibers are oriented approximately orthogonal to the surface of the compound material; splitting the compound material to expose the glass fibers, wherein the glass fibers extend from the surface of the compound material; and forming the split compound material into a traction surface.

First claim

What is claimed is:

1. A traction surface comprising:
a compound material comprising a plastic material; and
glass fibers, the glass fibers oriented orthogonal to a surface of the compound material extending between approximately 250 to 450 micrometers from the compound material,
wherein:
when the traction surface contacts an icy surface, the glass fibers are operable to penetrate a liquid top layer of the icy surface to provide grip with an ice layer below the liquid top layer, and
the entire traction surface is formed of the compound material and at least a portion of the glass fibers.

2. The traction surface of claim 1 , wherein the traction surface is formed of a sheet having the glass fibers extending from at least one surface of the sheet.

3. The traction surface of claim 2 , wherein the sheet comprises a thickness of approximately 2 millimeters.

4. The traction surface of claim 1 , wherein the glass fibers are oriented within the compound material by rolling the glass fibers through a roller system, wherein an opening of the roller system is less than a length of the glass fibers.

5. The traction surface of claim 4 , wherein the glass fibers are further oriented within the compound material by stacking blocks of the compound material together and compressing the blocks together.

6. The traction surface of claim 1 , wherein the glass fibers are exposed on at least one surface of the compound material by splitting the compound material in a direction orthogonal to an orientation of the glass fibers.

7. The traction surface of claim 1 , wherein the traction surface is incorporated into an outsole for footwear.

8. The traction surface of claim 1 , wherein the traction surface comprises a plug operable to attach to an element that will contact icy surfaces.

9. The traction surface of claim 1 , wherein the compound material further comprises a vulcanized rubber material.

10. A traction surface comprising:
a compound material comprising a plastic material; and
glass fibers, the glass fibers oriented orthogonal to a surface of the compound material extending between approximately 250 to 450 micrometers from the compound material,
wherein:
when the traction surface contacts an icy surface, the glass fibers are operable to penetrate a liquid top layer of the icy surface to provide grip with an ice layer below the liquid top layer,
the entire traction surface is formed of the compound material and at least a portion of the glass fibers, and
the traction surface comprises a plug operable to attach to an element that will contact icy surfaces.
