Multi-layer wearable body armor

1. A multi-layer armor plate comprising:

a strike plate formed via additive manufacturing of metal matrix composite materials comprising a metal matrix and a nanocellulose supplement;

a mesh layer positioned over the strike plate, the mesh layer having a number of open cells; and

an outer skin layer positioned over the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer.

2. The armor plate set forth in claim 1 , wherein the strike plate has a multi-curved profile for conforming to a wearer's torso, an inner face for at least partially covering the wearer's chest, an outer strike face, upper corner concave reliefs for accommodating the wearer's arms, and lower corner concave reliefs for accommodating the wearer's hips and thighs.

3. The armor plate set forth in claim 2 , wherein the mesh layer is formed of metal and has an inner side positioned on the outer strike face of the strike plate and an outer side, with the open cells formed between the inner side and the outer side.

4. The armor plate set forth in claim 3 , wherein the open cells of the mesh layer entrap air.

5. The armor plate set forth in claim 1 , wherein the mesh layer has an outer side and the outer skin layer is formed of metal and has an inner face and an outer face, the inner face positioned over the outer side of the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer.

6. The armor plate set forth in claim 1 , further comprising expandable, buoyant foam that at least partially fills the open cells of the mesh layer.

7. A multi-layer, wearable body armor plate comprising:

a strike plate formed via additive manufacturing of metal matrix composite materials comprising a metal matrix and a nanocellulose supplement and having a multi-curved profile for conforming to the wearer's torso, an inner face for at least partially covering the wearer's chest, an outer strike face, upper corner concave reliefs for accommodating the wearer's arms, and lower corner concave reliefs for accommodating the wearer's hips and thighs;

a mesh layer having an inner side positioned on the outer strike face of the strike plate, an outer side, a number of open cells formed between the inner side and outer side, and edges between the inner side and the outer side; and

a metallic outer skin layer positioned over the outer side and the edges of the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer.

8. The body armor plate set forth in claim 7 , wherein the mesh layer is formed of metal.

9. The body armor plate set forth in claim 8 , wherein the open cells of the mesh layer entrap air.

10. The body armor plate set forth in claim 7 , further comprising expandable, buoyant foam that at least partially fills the open cells of the mesh layer.

11. A method of forming a multi-layer, wearable body armor plate comprising:

depositing a metal matrix composite material via additive manufacturing to form a strike plate having a multi-curved profile, an inner face, an outer strike face, upper corner concave reliefs, and lower corner concave reliefs;

depositing additional metal matrix composite material via additive manufacturing to form a mesh layer over the strike plate, the mesh layer having an inner side positioned on the outer strike face of the strike plate, an outer side, a number of open cells formed between the inner side and the outer side, and edges between the inner side and the outer side; and

depositing additional metal matrix composite material via additive manufacturing to form a metallic outer skin layer over the outer side and the edges of the mesh layer so as to encapsulate the open cells of the mesh layer between the strike plate and the outer skin layer.

12. The method as set forth in claim 11 , wherein the metal matrix composite materials comprise a metal matrix and a nanocellulose supplement.

13. The method as set forth in claim 11 , further comprising forming access holes in the mesh layer.

14. The method as set forth in claim 13 , further comprising injecting expandable, buoyant foam in the open cells of the mesh layer.

15. The method as set forth in claim 13 , further comprising sealing the access holes.

16. The method as set forth in claim 11 , further comprising designing the multi-curved profile of the strike plate so the strike plate conforms to a particular wearer's torso.
