Abstract
Provided are, among other things, systems, methods and techniques for making a shoe outsole and to shoe outsoles made using such techniques. In one such technique, a sheet of composite material is produced by extruding a base material together with a sheet of fabric material. The sheet of composite material is then cut into an outsole component, and a shoe outsole is fabricated using the outsole component.
Claims18
A method of making a composite material, comprising:
- (a) extruding a base material into a sheet of base material;
- (b) depositing a plurality of individual fibers onto a surface of the sheet of base material before the sheet of base material has fully hardened;
- and
- (c) pressing the individual fibers into the surface of the sheet of base material in order to form a sheet of composite material,
- wherein the sheet of composite material has a bottom layer of the base material alone and a thinner top layer into which the individual fibers have been embedded.

A method of making a composite material, comprising:
- (a) extruding a base material into a sheet of base material by at least one of pushing or drawing said base material through an extrusion die having a profile shape that is appropriate for producing said sheet;
- (b) depositing a plurality of individual fibers onto a surface of the sheet of base material before the sheet of base material has fully hardened;
- and
- (c) pressing the individual fibers into the surface of the sheet of base material in order to form a sheet of composite material,
- wherein the extrusion die is shaped so as to form a three-dimensional pattern in a surface of the sheet of base material that is being extruded.
