Abstract

Claims (31)

1. A flexible armor, comprising

a first layer of fiber weave material, wherein the first layer of fiber weave material forms an outermost layer on one side of the flexible armor;

a second layer of fiber weave material, wherein the second layer of fiber weave material forms an outmost layer opposite the first layer on the other side of the flexible armor;

an inner ceramic layer, wherein the inner ceramic layer is a single continuous piece of interlinked ceramic material that is in between the first layer of fiber weave material and the second layer of fiber weave material; and

a shear thickening fluid, wherein the inner ceramic layer is coated in the shear thickening fluid and the shear thickening fluid fills open space within the inner ceramic layer.

2. The flexible armor of claim 1 , wherein the first layer of fiber weave material and the second layer of fiber weave material are selected from a group consisting of Kevlar, ballistic nylon, or a combination thereof.

3. The flexible armor of claim 1 , wherein the inner ceramic layer is selected from a group consisting of alumina, boron carbide, silicon carbide, and titanium diboride.

4. The flexible armor of claim 1 , wherein the shear thickening fluid is a colloid.

5. The flexible armor of claim 1 , wherein the flexible armor is a garment.

6. The flexible armor of claim 1 , wherein the flexible armor is a blanket.

7. The flexible armor of claim 1 , wherein the inner ceramic layer is any ceramic material capable of being 3D printed.

8. A flexible armor, comprising:

a first layer of fiber weave material, wherein the first layer of fiber weave material forms an outermost layer on one side of the flexible armor;

a second layer of fiber weave material, wherein the second layer of fiber weave material forms an outmost layer opposite the first layer on the other side of the flexible armor;

an inner ceramic layer, wherein the inner ceramic layer is a single continuous piece of interlinked ceramic material that is in between the first layer of fiber weave material and the second layer of fiber weave material; and

a shear thickening fluid, wherein the shear thickening fluid is coated onto the first layer of fiber weave material, the second layer of fiber weave material, the inner ceramic layer, or a combination thereof.

9. The flexible armor of claim 8 , wherein the first layer of fiber weave material and the second layer of fiber weave material are selected from a group consisting of Kevlar, ballistic nylon, or a combination thereof.

10. The flexible armor of claim 8 , wherein the inner ceramic layer is selected from a group consisting of alumina, boron carbide, silicon carbide, and titanium diboride.

11. The flexible armor of claim 8 , wherein the shear thickening fluid is a colloid.

12. The flexible armor of claim 8 , wherein the flexible armor is a garment.

13. The flexible armor of claim 8 , wherein the flexible armor is a blanket.

14. The flexible armor of claim 8 , wherein the inner ceramic layer is any ceramic material capable of being 3D printed.

15. A method of making flexible armor, comprising:

3D printing an inner ceramic layer, wherein the inner ceramic layer is a single continuous piece of interlinked ceramic material;

attaching a first layer of fiber weave material to a second layer of fiber weave material, thereby enclosing the inner ceramic layer within the first and second layer of fiber weave material, wherein the first layer of fiber weave material forms an outermost layer on one side of the flexible armor and the second layer of fiber weave material forms an outmost layer opposite the first layer of fiber weave material on the other side of the flexible armor; and

coating a first layer of fiber weave material, a second layer of fiber weave material, the inner ceramic layer, or a combination thereof in shear thickening fluid, wherein the first layer of fiber weave material or the second layer of fiber weave material is coated in shear thickening fluid prior to attaching and the inner ceramic layer is coated in shear thickening fluid after attaching by leaving an opening between the first layer of fiber weave material and second layer of fiber weave material to form a pouch with the inner ceramic layer therein prior to completing the attaching of the first layer of fiber weave material and second layer of fiber weave material and adding the shear thickening fluid to the pouch onto the inner ceramic layer and then completing the attaching the first layer of fiber weave material and second layer of fiber weave material together.

16. The method of claim 15 , wherein the first layer of fiber weave material and the second layer of fiber weave material are selected from a group consisting of Kevlar, ballistic nylon, or a combination thereof.

17. The method of claim 15 , wherein the inner ceramic layer is selected from a group consisting of alumina, boron carbide, silicon carbide, and titanium diboride.

18. The method of claim 15 , wherein the shear thickening fluid is a colloid.

19. The method of claim 15 , wherein the inner ceramic layer is any ceramic material capable of being 3D printed.

20. The method of claim 15 , wherein the flexible armor forms a garment or a blanket.
