US12663241 - Ballistic resistant material made of mechanically entangled woven fabrics without nonwoven fibers and method of making thereof

A consolidated material and method for forming a consolidated material. The consolidated material comprises a plurality of woven fabric layers that are mechanically entangled together. The plurality of woven fabric layers comprise fibers. The plurality of woven fabric layers are mechanically entangled together with fibers of the plurality of woven fabric layers and without nonwoven fibers. At least some fibers of the plurality of woven fabric layers extend in the Z-direction perpendicular to the x-y plane of the plurality of woven fabric layers. Methods for forming a consolidated material are also provided.

The patent describes a ballistic-resistant material made from mechanically entangled woven fabric layers without nonwoven fibers, designed to enhance impact resistance. This consolidated material features fibers extending in the Z-direction and meets specific thickness and ballistic performance standards.

Claim 1

1 . A consolidated material comprising: a plurality of woven fabric layers that are mechanically entangled together, wherein the plurality of woven fabric layers comprise fibers, wherein the plurality of woven fabric layers are mechanically entangled together with fibers of the plurality of woven fabric layers and without nonwoven fibers, wherein at least some fibers of the plurality of woven fabric layers extend in the Z-direction perpendicular to the x-y plane of the plurality of woven fabric layers, wherein the consolidated material has a thickness of from about 0.10 in. to about 2.0 in., wherein the consolidated material has a V50 in accordance with MIL STD-662F of from about 500 ft/s to about 20000 ft/s, and wherein some fibers of at least one woven fabric layer of the plurality of woven fabric layers extend in the Z-direction into at least one other woven fabric layer of the plurality of woven fabric layers. a plurality of woven fabric layers that are mechanically entangled together, wherein the plurality of woven fabric layers comprise fibers, wherein the plurality of woven fabric layers are mechanically entangled together with fibers of the plurality of woven fabric layers and without nonwoven fibers, wherein at least some fibers of the plurality of woven fabric layers extend in the Z-direction perpendicular to the x-y plane of the plurality of woven fabric layers, wherein the consolidated material has a thickness of from about 0.10 in. to about 2.0 in., wherein the consolidated material has a V50 in accordance with MIL STD-662F of from about 500 ft/s to about 20000 ft/s, and wherein some fibers of at least one woven fabric layer of the plurality of woven fabric layers extend in the Z-direction into at least one other woven fabric layer of the plurality of woven fabric layers.
