Abstract

An armor system includes an appliqué comprising a high fluid retaining material (HFRM) and a plate configured to hold the appliqué against a compartment, wherein the armor system is adapted so that upon impact of a blast wave upon the plate, the HFRM is vented away from the compartment. The armor system may be adapted to a vehicle. In another embodiment, an armor system includes a plate operably connected to a plunger, one or more rods of brittle material operably contained within a tube, wherein the armor system is adapted so that upon impact of a blast shock wave upon the plate, the plate transfers the blast shock wave to the plunger and then to the contents of the tube. Optionally, the tube also contains HFRM.

Claims (20)

1. An armor system comprising:

A compartment;

an applique comprising a high fluid retaining material (HFRM) in the form of small distributed volumes of HFRM adjacent to air, such that the HFRM is shear thinning with a viscosity that decreases with increased stress, and

a plate configured to hold the applique against the compartment and contain the HFRM,

wherein the armor system is configured so that upon impact of a blast wave upon the plate, the HFRM is directed away from the compartment.

2. The armor system of claim 1 , wherein said HFRM is selected from sodium polyacrylate and polyvinyl alcohol.

3. The armor system of claim 1 , wherein said HFRM is in a condition of being at least 90% hydrated.

4. The armor system of claim 1 , wherein said HFRM comprises beads and when said beads are in a condition of being dried, a majority said beads have sizes between 150 μm and 500 μm.

5. The armor system of claim 1 , wherein the compartment is V-shaped.

6. The armor system of claim 1 , wherein the plate comprises metal, plastic, laminate, or a combination thereof.

7. An armored vehicle comprising:

a compartment;

an applique on an exterior of the compartment, the applique comprising a high fluid retaining material (HFRM) in the form of small distributed volumes of HFRM adjacent to air, such that the HFRM is shear thinning with a viscosity that decreases with increased stress, and

a plate configured to hold the applique in place and contain the HFRM,

wherein the armor system is configured so that upon impact of a blast wave upon the plate, the high fluid retaining material is directed away from the compartment.

8. The armor system of claim 7 , wherein said HFRM is selected from sodium polyacrylate and polyvinyl alcohol.

9. The armor system of claim 7 , wherein said HFRM is in a condition of being at least 90% hydrated.

10. The armor system of claim 7 , wherein said HFRM comprises said beads and when said beads are in a condition of being dried, a majority said beads have sizes between 150 μm and 500 μm.

11. The armor system of claim 7 , wherein the compartment is V-shaped.

12. The armor system of claim 7 , wherein the plate comprises metal, plastic, laminate, or a combination thereof.
