Abstract

A woven fabric from yarn for use in the manufacture of ballistic projectile or puncture resistant articles where the fabric has a first plurality of parallel oriented yarns within the plane of the fabric interwoven with a second plurality of parallel oriented yarns within the plane of the fabric having a direction / orientation within the plane of the fabric different from that of the first plurality and where the crossing of any fiber yarn from the first plurality with a fiber yarn from the second plurality forms a pair of acute vertical angles having an angular measurement less than 90 degrees.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to fabric architectures and soft body armors constructed therefrom.

[0003] 2. Description of the Related Art

[0004] Protective body armors such as those providing protection against ballistic and stab type threats have long been an area of significant interest. One challenge for body armor manufacturers is to provide adequate protection from a particular threat or threats that the wearer may be subjected to in the field, while minimizing the weight, or areal density of the protective garment so as not to impede the dexterity of the wearer.

[0005] Characterization of the protective capabilities of any armor material against ballistic projectile threats, such as deformable bullets and non-deformable shrapnel, requires some determination of the ballistic velocity limit with respect to the material's areal density and size, as well as the properties of the projectile (mass, hardness, shape, etc.). On...
