The patent describes a ballistic material composed of a woven co-polymer ballistic fabric combined with a hydroentangled nonwoven fiber component made from ballistic grade para-aramid fibers. This innovative construction aims to enhance the density and performance of the ballistic product by utilizing low denier fibers.

Claim 1

1 . A ballistic material, comprising: a first woven co-polymer ballistic fabric having a fiber denier in a range of 50 d to 5000 d; and a hydroentangled nonwoven fiber component consisting essentially of ballistic grade para-aramid fibers having a denier in a range of about 0.5 d to about 2.5 d and a density of about 10 gsm to about 200 gsm; wherein the hydroentangled nonwoven fiber component is needlepunched with the first woven co-polymer ballistic fabric to form a consolidated material. a first woven co-polymer ballistic fabric having a fiber denier in a range of 50 d to 5000 d; and a hydroentangled nonwoven fiber component consisting essentially of ballistic grade para-aramid fibers having a denier in a range of about 0.5 d to about 2.5 d and a density of about 10 gsm to about 200 gsm; wherein the hydroentangled nonwoven fiber component is needlepunched with the first woven co-polymer ballistic fabric to form a consolidated material.
