Armor component and method of making the armor component
An armor component that includes a ballistic tile made of, for example, boron carbide or silicon carbide, a plurality of wraps made of ballistic fibers such as carbon fiber, and a metal plate, for example, a steel plate, the metal plate being positioned behind the reverse side of the tile and the wraps being wrapped around the tile and the metal plate.
1. An armor component comprising:
a tile wrapped with a plurality of polymer impregnated wrappers, the tile including an obverse side, a reverse side, and a plurality of corners, and the plurality of wrappers including at least a first wrapper and at least a second wrapper, each wrapper having a central portion and a plurality of leaves surrounding and extending from the central portion, the central portion of the first wrapper residing over the obverse side of the tile, and the leaves of the first wrapper being folded over to the reverse side of the tile; the central portion of the second wrapper residing over the reverse side of the tile, and the leaves of the second wrapper being folded over to the obverse side of the tile and the central portion of the first wrapper;
a metal plate positioned between the reverse side of the tile and the central portion of the second wrapper,
wherein the obverse side of the tile is the strike face of the tile.
2. The component of claim 1 , wherein the tile comprises boron carbide, the polymer comprises cured epoxy and the wrappers comprise carbon fibers or glass fibers.
3. The component of claim 1 , wherein the plurality of wrappers include at least a third wrapper and a fourth wrapper, each having a central portion, the central portion of the third wrapper residing on the reverse side of the tile between the metal plate and the reverse side of the tile, and the central portion of the fourth wrapper being positioned on the second wrapper,
the leaves of the third wrapper and the leaves of the fourth wrapper being folded over the obverse side of the tile, and the leaves of each wrapper have varying lengths, the shortest leaves being closer to the corners of the tile.
4. The component of claim 1 , wherein at least the polymer in the first wrapper penetrates microscopic surface cavities of the tile to mechanically bond the first wrapper to the ceramic tile.
5. The component of claim 1 , wherein the corners of the tile are rounded.
6. A component according to claim 1 , wherein the tile includes an endless edge between the obverse side and the reverse side, the tile including a profile between the obverse side and the reverse side, the profile including a first peripheral boundary, a second peripheral boundary opposite the first peripheral boundary, a third peripheral boundary extending between the first and the second peripheral boundaries and connected to the first and to the second peripheral boundaries by respective corners, and a fourth peripheral boundary opposite the third peripheral boundary, extending between the first and the second peripheral boundaries and connected to the first and to the second peripheral boundaries by respective corners, the first and the second peripheral boundaries having one shape, and the third and the fourth boundaries having another shape different than the one shape, wherein the obverse side includes a first region and a second region each configured to be overlapped by a corresponding region of a reverse side of another tile, and the strike face that is not overlapped by another tile, the first region and the second region being adjacent the strike face and wherein the strike face includes a relief pattern comprising a plurality of raised portions.
7. The component of claim 6 , wherein the first and second regions each includes a feature that registers with a corresponding feature on the reverse side of a respective overlapping tile.
8. The component of claim 6 , wherein the first region and the second region each slopes downwardly from the strike face toward respective first and second peripheral boundaries and are overlapped by corresponding regions on the reverse side of respective tiles.
9. The component of claim 6 , wherein each raised portion is arcuate and includes a convex outer surface.
10. The component of claim 6 , wherein the strike face includes a relief pattern comprising a single, continuous raised surface.
11. The component of claim 6 , wherein the tile is comprised of sintered silicon carbide.
