Armouring solution 2

Protective solution made with metallic and textile composite to cope with fragment projectile FSP (20 mm – 54g) at 630 m/s (STANAG 4569 norm)

Several textile composite solutions have been made with layers of 3D warp interlock fabric using para-aramid yarns or aromatic polyester yarns combined with three different types of architecture.

The first 3D warp interlock fabric architecture is:

3D warp interlock O – L 1-2-13 Binding {Plain weave}{1 13 – 2 14 – 3 15 – 4 16 – 5 17 – 6 18 – 7 19 – 8 20 – 9 21 – 10 22 – 11 23 – 12 24 – # – #} – Surface {Plain weave}{25 – # – # – # – # – # – # – # – # – # – # – # – 26 – #}

The second 3D warp interlock fabric architecture is:

3D warp interlock O – T 1-11-11 Binding {plain weave}{1 2 – #- #- #- #- #- #- #- #- #- #- #} – Stuffer {# – 3 – 4 -5 – 6 –7 – 8 – 9 – 10 – 11 – 12 – #}

The third 3D warp interlock fabric architecture is:

3D warp interlock A – T 11-6-6 Binding {Pattern Twill 6 weft effect left shift (Pattern = {1 up 11 down – 6 down 1 up 5 down})}{1 2 3 4 5 6 7 8 9 10 11 12 – # – # – # – # – # – #}

Protective solutions to FSP impacts (20 mm – 54 g) have been successful up to 630 m/s for architecture with orthogonal and layer-to-layer binding warp yarns.
