Abstract

Methods and apparatus for providing ballistic protection and stopping high-velocity rounds or explosives. The apparatus may include a ballistic panel for providing ballistic protection. The ballistic panel includes a core that includes a plurality of node cells, an intermediate layer that surrounds the core and fills in the node cells, and an outer coating. The ballistic panel absorbs the force of high-velocity, ballistic, low-velocity, and high foot pound pressure rounds, fragments, and impacts and is capable of completely capturing such ballistic rounds and fragments without external deflection or complete penetration through ballistic panel.

Claims

1. A ballistic panel for providing ballistic protection comprising:

a three-dimensional core that includes a plurality of node cells and provides structural support of the ballistic panel, wherein the core approximates an octet truss;

an intermediate layer that surrounds the core and fills in the node cells; and

an outer coating that substantially surrounds and encapsulates the intermediate layer, wherein the ballistic panel absorbs the force of ballistic rounds of multiple velocities and multiple pressures, fragments, and impacts and is capable of completely capturing such ballistic rounds and fragments without external deflection or complete penetration through ballistic panel.

2. The ballistic panel of claim 1 wherein the intermediate layer is a ceramic layer.

3. The ballistic panel of claim 2 wherein the ceramic layer includes ceramic spheres and a bonding media that bonds the ceramic spheres together.

4. The ballistic panel of claim 3 wherein the bonding media is a bonding urethane.

5. The ballistic panel of claim 1 wherein outer coating is a polymer.

6. The ballistic panel of claim 5 wherein the outer coating polymer is an elastomeric polyurethane, solvent free 100% solids.

7. The ballistic panel of claim 1 wherein core is plastic.

8. The ballistic panel of claim 1, further comprising a force-absorbing backing.

9. The ballistic panel of claim 1 wherein the ballistic panel is mounted on a material with force-absorbing properties.

10. The ballistic panel of claim 1 wherein the intermediate layer is of differing thickness on either side of core.

11. The ballistic panel of claim 1 wherein the intermediate layer comprises ceramic spheres and the node cells include nodes that are of approximately the same diameter of the ceramic spheres.

12. The ballistic panel of claim 1 wherein the core is flexible and bendable.

13. The ballistic panel of claim 12 wherein the ballistic panel is curved.

14. An apparatus comprising a plurality of ballistic panels of claim 1 interlocked and joined together.

15. A vehicle door comprising a ballistic panel according to claim 1.

16. A building block comprising a plurality of ballistic panels according to claim 1.

17. A ballistic panel for providing ballistic protection comprising:

a three-dimensional core that includes a plurality of node cells and provides structural support of the ballistic panel, wherein the core defines a tetrahedron- and octahedron shape;

an intermediate layer that surrounds the core and fills in the node cells; and

an outer coating that substantially surrounds and encapsulates the intermediate layer, wherein the ballistic panel absorbs the force of ballistic rounds of multiple velocities and multiple pressures, fragments, and impacts and is capable of completely capturing such ballistic rounds and fragments without external deflection or complete penetration through ballistic panel.
