Abstract

A method for manufacturing a ballistic resistance package which includes providing a molecularly oriented tape material having a front face and back face with a minimum of two sets of parallel side faces; wrapping molecularly oriented fabric material around the front and back faces and a set of the parallel side faces of the molecularly oriented tape material, yielding a wrapped core structure; and finalizing the wrapped core structure to yield the ballistic resistance package. A multifunction ballistic resistance system for resisting projectiles and/or mitigating blast effects of explosions. The multifunction ballistic resistance system may include: at least one cellular frame defining cells therein, and a plurality of molecularly oriented tape material core structures wrapped in molecularly oriented fabric material and finalized, and attached to at least one cellular frame.

First claim

We claim:

1. A method for manufacturing a ballistic resistance package, comprising:
providing a core comprised of a molecularly oriented tape material having a front face and back face with a minimum of two sets of parallel side faces, wherein said molecularly oriented tape material comprises ultrahigh molecular weight polyethylene (UHMWPE) or aramid molecules; and wherein:
said core of said molecularly oriented tape material further comprises a plurality of layers of tape material wherein a most outer of plurality of layers defines said front and back faces of said molecularly oriented tape material,
said core of said molecularly oriented tape material comprising a plurality of layers of tape material that occupies all of an area between said front face, said back face, and said minimum of two sets of parallel side faces so as to define a completely tape-filled area between said front face, said back face, and said minimum of two sets of parallel side faces,

wrapping molecularly oriented fabric material around said front and back faces and a set of said parallel side faces of said molecularly oriented tape material, yielding a wrapped core structure, wherein said molecularly oriented fabric material comprises ultrahigh molecular weight polyethylene (UHMWPE) or aramid molecules; and wherein:
said wrapping of the molecularly oriented tape material comprises at least two separate units of molecularly oriented fabric material wrapped in unique directions, and

finalizing the wrapped core structure to yield the ballistic resistance package.

2. The method of claim 1 , wherein said finalizing the ballistic resistance package comprises one or more of the following:
consolidating the wrapped core structure by using a hot press and an autoclave; infiltration of a dry tape material with resin by vacuum assisted resin transfer molding (VARTM); applying an adhesive to prevent the wrapped core from unraveling; or sewing the end of the wrapped core to the outer wrapped surface of the wrapped core.

3. The method of claim 1 , wherein the molecularly oriented tape material is in a woven, ply, pre-preg or laminate form.

4. The method of claim 1 , wherein the molecularly oriented tape material comprises at least one or more of the following:
alumina, boron carbide, carbon, glass, para-aramid, Zylon , PIPD, polyamide, silicon carbide, or titanium carbide fibers.

5. The method of claim 1 , further comprising inserting at least one ballistic resistance package into a cellular frame, wherein said cellular frame is configured to accommodate said ballistic resistance package inserted therein.

6. The method of claim 5 , wherein said cellular frame is configured as a honeycomb lattice structure.

7. The method of claim 5 , further comprising disposing said cellular frame onto a plate to form a door.

8. The method claim 5 , further comprising disposing said cellular frame into a load bearing member so as to be part of said static load bearing member, wherein said loadbearing member is of any one of:
an architectural structure, a civil engineering structure, a military security/protection/defense structure, a machine structure, an automobile structure, a ship structure, a freight car structure, an aircraft structure, a spacecraft structure, a space station structure, and a submarine, structure.

9. The method of claim 1 , wherein the molecularly oriented fabric material is in a woven, ply, pre-preg or laminate form.

10. The method of claim 1 , wherein the molecularly oriented fabric material comprises at least one or more of the following:

Zylon, PIPD, polyamide, silicon carbide, or titanium carbide fibers.

11. The method of claim 1 , wherein the at least two separate units of molecularly oriented fabric material wrapped in unique directions alternate wrapping the molecularly oriented tape material sequentially.

12. The method of claim 1 , wherein wrapping the molecularly oriented tape material in said molecularly oriented fabric material comprises creation of multiple layers of wrapped molecularly oriented fabric material covering the molecularly oriented tape material panel.

13. A ballistic resistance package, comprising:
a core comprised of molecularly oriented tape material having a front face and back face with a minimum of two sets of parallel side faces, and wherein said molecularly oriented tape material comprises ultrahigh molecular weight polyethylene (UHMWPE) or aramid molecules; and wherein:
said core of said molecularly oriented tape material further comprises a plurality of layers of tape material wherein a most outer of plurality of layers defines said front and back faces of said molecularly oriented tape material,
said core of said molecularly oriented tape material comprising a plurality of layers of tape material that occupies all of an area between said front face, said back face, and said minimum of two sets of parallel side faces so as to define a completely tape-filled area between said front face, said back face, and said minimum of two sets of parallel side faces,

a molecularly oriented fabric material wrapped around said front and back faces and a set of said parallel side faces of said molecularly oriented tape material, yielding a ballistic resistance package after it has been finalized, and wherein said molecularly oriented fabric material comprises ultrahigh molecular weight polyethylene (UHMWPE) or aramid molecules, and wherein:
