An armor system pellet and an array and armor composed therefrom are provided. The pellet includes a pellet body and a plurality of projections for interlocking adjacent pellets when arranged in an array. The projections are configured for maximizing a contact area between adjacent pellets without substantially restricting independent movement of each of the pellets.
1. An armor system comprising an array of pellets, each having a pellet body and four finger-like projections extending radially outwardly from said pellet body, each of said four finger-like projections of a pellet being capable of contacting three finger-like projections of adjacent pellets when arranged in a single layer array for maximizing a contact area between adjacent pellets, wherein each of said pellets is capable of independent side to side movement within said array and is further capable of independently pitching with respect to a surface of said array in response to a projectile impact on a finger-like projection of said four finger-like projections.
2. The armor system pellet of claim 1 , wherein said maximizing a contact area between adjacent pellets maximizes a transfer of an impact force of said projectile from said pellet to said adjacent pellets.
3. The armor system pellet of claim 1 , being composed of a ceramic material.
4. The armor system pellet of claim 3 , wherein said ceramic material includes a material selected from the group consisting of alumina, boron carbide, boron nitride, silicon carbide, silicon nitride, and zirconium oxide.
5. The armor system pellet of claim 1 , wherein a front surface of the pellet is convex.
6. The armor system pellet of claim 5 , wherein a front surface of each of said four finger-like projections is convex.
7. The armor system pellet of claim 1 , wherein a largest diameter of the pellet exceeds a largest height thereof.
8. The armor system of claim 1 , further comprising front and back plates sandwiching said array.
9. The armor system of claim 8 , further comprising a polymer resin disposed between said array and said front and/or back plates.
10. The armor system of claim 9 , wherein each of said pellets is capable of said independent side to side movement with respect to said polymer resin.
11. The armor system of claim 8 , further comprising a flexible support structure for securing said array to said front and/or back plates.
12. The armor system of claim 11 , further comprising connectors for interconnecting said front and back plates through said support structure.
13. The armor system of claim 8 , further comprising a shock absorbing layer disposed between said front and back plates.
14. The armor system of claim 8 , wherein each of said pellets is capable of said independent side to side movement with respect to said front and back plates sandwiching said array.
15. The armor system of claim 1 , comprising at least two layers of said array.
16. The armor system of claim 1 , further comprising a high tensile strength fabric disposed around said array.
17. The armor system of claim 16 , wherein said fabric includes carbon fibers, fiberglass fibers, aramid fibers and/or metallic fibers.
18. The armor system of claim 1 , configured as body armor.
19. The armor system of claim 1 , configured as vehicle armor.
