Abstract

The method is for receiving a bullet in a bullet proof vest. A plate structure is provided that has an airtight enclosure enclosing high performance fiber layers, a hard layer, a textile layer having openings defined therein and a semi-solid layer such as bitumen. A bullet penetrates through the airtight enclosure. The pressure inside the airtight enclosure is increased. The increased pressure separates the layers from the hard layer and the textile layer from the hard layer. The hard layer deforms the bullet. The textile layer attaches to the bullet to follow the bullet. The layer sticks to the bullet as the bullet penetrates through the plate structure.

Claims

1. A method of receiving a bullet, comprising:

providing a plate structure having an airtight enclosure enclosing high performance fiber layers, a hard layer, a textile layer having openings defined therein and a semi-solid layer;

a bullet penetrating through the airtight enclosure increasing a pressure and expanding a volume inside the airtight enclosure;

the increased pressure and volume separating the layers from the hard layer and the textile layer from the hard layer;

the hard layer deforming the bullet;

the textile layer attaching to the bullet to follow the bullet; and

the semi-solid layer sticking to the bullet.

2. The method according to claim 1 wherein the method further comprises inserting the plate structure into a pocket of a vest.

3. The method according to claim 1 wherein the method further comprises attaching a side plate to a lower edge of the vest.

4. The method according to claim 1 wherein the method further comprises the increased pressure expanding the enclosure to create room between the layers.

5. The method according to claim 1 wherein the method further comprises providing the plate structure with a polymeric layer having a plurality of air-bubbles.

6. The method according to claim 5 wherein the method further comprises the polymeric layer transversely spreads out penetration energy of the bullet.

7. The method of claim 1 wherein the method further comprises placing a trauma plate behind the plate structure.

8. The method of claim 1 wherein the method further comprises removably attaching a gas mask bag on a rear section of the vest.

9. The method of claim 1 wherein the method further comprises the textile layer being a woven fiberglass, the woven fiberglass attaching to the bullet and the semi-solid material.

10. The method according to claim 1 wherein the method further comprises providing a second textile layer and a second semi-solid layer, the layer and the layer sticking to the bullet.
