TECHNOLOGY:
Ballistic Resistant Article Comprising a Three Dimensional Interlocking Woven Fabric

DESCRIPTION:
In order to protect military and law enforcement personnel from the hazards of projectiles, protective articles of clothing such as vests, shirts and caps are provided. This invention provides a woven material exhibiting improved ballistic resistance.

This technology provides a material possessing improved ballistic resistance while being thinner than typically available articles exhibiting similar protection characteristics. This thickness advantage makes it possible to provide relatively low weight materials that exhibit satisfactory resistance. These advantages are achieved by employing a suitable three-dimensional weave configuration. This configuration is such that the yarns impede the penetration of an impinging projectile to a far greater extent than that experienced in conventional 2-dimensional weave configurations.

In typical two-dimensionally woven ballistic resistant materials, the impinging projectile tends to separate the warp and fill yarns. This separation makes it necessary to stack together several layers of woven material to provide any degree of resistance. The more layers that are required, the heavier and less comfortable the body armor becomes. Utilizing a three-dimensional weave enables the same degree of protection to be achieved with a thinner material.
