Abstract

The invention relates to a ballistic vest which offers a ballistic resistance meeting NIJ2 Standard 0101.03 and comprises a stack of flexible unidirectional layers in which the unidirectional layers contain strong fibers and in which the fibers in a unidirectional layer run substantially parallel and are positioned at an angle of more than 0 degrees relative to fibers in an adjacent layer, said fibres being PBO fibres.

Claims (4)

1. Ballistic vest having a ballistic resistance meeting NIJ2 Standard 0101.03 and comprising a stack of flexible unidirectional layers in which the unidirectional layers contain strong fibres and in which the fibres in a unidirectional layer run substantially parallel and are positioned at an angle of more than 0 degrees relative to fibres in an adjacent layer, wherein the fibres are PBO fibres, and further wherein the areal density is less than 3.23 kg/m 2 .

2. Ballistic vest according to claim 1 , wherein the areal density is less than 2.8 kg/m 2 .

3. Ballistic vest according to claim 1 , wherein the PBO is an as-spun grade, with Tensile modulus below 1200 cN/dTex.

4. Ballistic vest according to claim 2 , wherein the PBO is an as-spun grade, with Tensile modulus below 1200 cN/dTex.
