Vibration dampening material and method of making same
View Patent ↗An insert for a shoe formed by a reinforced elastomer material that regulates and dissipates vibration.
1. An insert for a shoe, comprising:
a shoe insert body having a generally elongated shape with an outer perimeter configured to substantially conform to a sole of the shoe so that the shoe insert body extends along an inner surface of the shoe from a location proximate to a heel of the shoe to a toe of the shoe, the shoe insert body being generally planar and formed by a reinforced elastomer material that regulates and dissipates vibration, the shoe insert body having first and second major surfaces, the reinforced elastomer material comprising:
first and second elastomer layers; and
a reinforcement layer disposed between and generally separating the first and second elastomer layers, the reinforcement layer comprising a cloth layer formed of a plurality of woven high tensile fibrous material, the plurality of woven high tensile fibrous material being connected to the first and second elastomer layers generally uniformly throughout to provide substantially complete coverage between the first and second elastomer layers, the cloth layer being generally compliant only in a direction generally perpendicular to the first major surface so as to be generally non energy storing in the direction, wherein the high tensile fibrous material generally distributes impact energy parallel to the first major surface and into the first and second elastomer layers.
2. The insert of claim 1 , wherein the reinforcement layer is generally coextensive with the shoe insert body.
3. The insert of claim 2 , wherein the reinforcement layer is generally parallel to the first major surface.
4. The insert of claim 1 , wherein the cloth layer generally separates the first and second elastomer layers and generally provides uniform coverage therebetween.
5. The insert of claim 1 , wherein the first and second elastomer layers are formed by thermoset elastomer.
6. The insert of claim 1 , wherein the reinforcement layer consists only of the cloth layer.
7. The insert of claim 1 , wherein the high tensile fibrous material is an aramid.
8. The insert of claim 1 , wherein the cloth layer is generally interlocked in and generally held in position by the first and second elastomer layers.
9. The insert of claim 1 , wherein the cloth layer is generally embedded in and generally held in position by the first and second elastomer layers.
10. The insert of claim 1 , wherein the cloth layer is generally held in position by the first and second elastomer layers to prevent sliding movement therebetween in a direction parallel to the first major material surface.
11. An insert for a shoe, comprising:
a shoe insert body having a generally elongated shape with an outer perimeter configured to substantially conform to a sole of the shoe so that the shoe insert body extends along an inner surface of the shoe from a location proximate to a heel of the shoe to a toe of the shoe, the shoe insert body being generally planar and formed by a reinforced elastomer material that regulates and dissipates vibration, the shoe insert body having first and second major surfaces, the reinforced elastomer material comprising:
first and second elastomer layers; and
a reinforcement layer disposed between and generally separating the first and second elastomer layers, the reinforcement layer comprising a cloth layer formed of fiberglass, the fiberglass being connected to the first and second elastomer layers generally uniformly throughout to provide substantially complete coverage between the first and second elastomer layers, the cloth layer being generally compliant only in a direction generally perpendicular to the first major surface so as to be generally non energy storing in the direction, wherein the fiberglass generally distributes impact energy parallel to the first major surface and into the first and second elastomer layers.
12. The insert of claim 11 , wherein the reinforcement layer is generally coextensive with the shoe insert body.
13. The insert of claim 12 , wherein the reinforcement layer is generally parallel to the first major surface.
14. The insert of claim 11 , wherein the cloth layer generally separates the first and second elastomer layers and generally provides uniform coverage therebetween.
15. The insert of claim 11 , wherein the first and second elastomer layers are formed by thermoset elastomer.
16. The insert of claim 11 , wherein the reinforcement layer consists only of the cloth layer.
17. The insert of claim 11 , wherein the cloth layer is generally interlocked in and generally held in position by the first and second elastomer layers.
18. The insert of claim 1 , wherein the cloth layer is generally embedded in and generally held in position by the first and second elastomer layers.
19. The insert of claim 1 , wherein the cloth layer is generally held in position by the first and second elastomer layers to prevent sliding movement therebetween in a direction parallel to the first major material surface.
20. An insert for a shoe, comprising:
a shoe insert body having a generally elongated shape with an outer perimeter configured to substantially conform to a sole of the shoe so that the shoe insert body extends along an inner surface of the shoe from a location proximate to a heel of the shoe to a toe of the shoe, the shoe insert body being generally planar and formed by a reinforced elastomer material that regulates and dissipates vibration, the shoe insert body having first and second major surfaces, the reinforced elastomer material comprising:
first and second elastomer layers; and
a reinforcement layer disposed between and generally separating the first and second elastomer layers, the reinforcement layer being generally coextensive with the shoe insert body, the reinforcement layer consisting of a cloth layer formed of a plurality of woven high tensile fibrous material, the plurality of woven high tensile fibrous material being connected to the first and second elastomer layers generally uniformly throughout to provide substantially complete coverage between the first and second elastomer layers, the cloth layer being generally compliant only in a direction generally perpendicular to the first major surface so as to be generally non energy storing in the direction, the cloth layer is generally interlocked in and generally held in position by the first and second elastomer layers, wherein the high tensile fibrous material generally distributes impact energy parallel to the first major surface and into the first and second elastomer layers.
