Auxetic Materials

How Auxetic Materials Works

Stretch a bungee cord and it gets thinner. But wrap a string around it and stretch‚ and it gets effectively wider. This is how Auxetic Material mitigates blasts. Weaving these wrapped cords into bundles creates an Auxetic Structure that thickens when subjected to explosive forces. Blast Control’s Pressure ProTM and Blast ProTM products are constructed utilizing materials weaved in an Auxetic arrangement

Auxetic Fabric Design Principle

The performance of Auxetic Materials in ballistic curtain and tent applications is directionally dependent, meaning that the length of the curtain or height of the tent is equivalent to the width of a roll of Auxetic Materials fabric.

  • The HAY is a fiber structure comprised of two components
  • HAY fiber structure: One fiber is helically wrapped around a core fiber
  • Under tension, the wrap tends to straighten causing the core to displace laterally in a helical manner
