System to make a ballistic material
View Patent ↗A system for making a ballistic material resistant to penetration from bullets, shrapnel, debris, and other lethal missiles, comprising: means for dyeing a flexible conformable low surface energy fabric; a roll coating device for continuously coating a top surface of the dyed fabric with an acrylic based adhesive; an extruder for applying a liner; at least one nip roller for receiving the liner and the coated fabric and applying the liner to the coated fabric; at least one displacement slitter for cutting the coated lined fabric; a fabric printer for printing the cut lined fabric with a fast drying acrylic ink forming a ballistic material up to 300% thicker than the flexible conformable low surface energy fabric; and a continuous cutter for cutting the ballistic material into a desired shape.
1. A system for making a ballistic material resistant to penetration from bullets, shrapnel, debris, and other lethal missiles, comprising:
means for dyeing a flexible conformable low surface energy fabric, forming a dyed fabric, wherein the flexible conformable low surface energy fabric has a first thickness of at least three mils;
a roll coating device for continuously coating a top surface of the dyed fabric with an acrylic based adhesive, forming a coated fabric;
an extruder for applying a liner to the coated fabric;
at least one nip roller for receiving the liner and the coated fabric simultaneously and pressurably applying the liner to the coated fabric, forming a coated lined fabric;
at least one displacement slitter for receiving the coated lined fabric and cutting the coated lined fabric into at least one desired size, forming a cut lined fabric;
a fabric printer for printing the cut lined fabric with a fast drying acrylic ink, forming a ballistic material having a second thickness up to 300% larger than the first thickness and which is tough, resistant to bullet penetration from a range of six feet from the ballistic material; and
a continuous cutter for cutting the ballistic material into a desired shape.
2. The system of claim 1 , wherein the means for dying, the roll coating device, the extruder, the at least one nip roller, the at least one displacement slitter, and the fabric printer are connected for performing a continuous process.
3. The system of claim 2 , wherein the continuous process is managed by a processor connected to a network.
4. The system of claim 3 , wherein the means for dying, the roll coating device, the extruder, the at least one nip roller, the at least one displacement slitter, and the fabric printer are in wireless communication with the network and the processor.
5. The system of claim 1 , wherein the fabric printer deposits a member of the group consisting of: a bar code, a radio frequency identification tag, a serial number, or combinations thereof, on the cut lined fabric.
6. The system of claim 1 , wherein the fabric printer is a flexographic printing press.
7. The system of claim 6 , wherein the fabric printer comprises a curing component for curing the fast drying acrylic ink using ultraviolet light, direct heat, or convection heat.
8. The system of claim 1 , further comprising a coater for applying a urethane coating to a surface of the flexible conformable low surface energy fabric.
9. The system of claim 1 , wherein the continuous cutter is a die cutter, a laser cutter, or combinations thereof.
10. The system of claim 1 , further comprising a die cutter for forming a “crack-and-peel” feature in the liner.
11. The system of claim 1 , further comprising a mixer for mixing a flame retardant, at least one additive, or combinations thereof into the acrylic based adhesive prior to coating the dyed fabric with the acrylic based adhesive.
