Chem-Bio Resistant Material

for Tents, Frames, and Portable Shelters

Warwick's engineers are experts in creating chem-bio resistant fabrics for tents and temporary structures

Integrating Chem-Bio Protection into Tent Materials
The threats presented by chemical and biological warfare and pandemic outbreak of airborne diseases demand that our emergency personnel be equipped with protective temporary structures.

Working with the Natick Soldier Center's Shelters Technology, Engineering & Fabrication Directorate (STEFD), Warwick has developed new chem-bio materials for structures that are designed to be more robust, as well as lower in weight, when compared to previously fielded tent offerings.

Chemical and Biological Proof Materials

Our chem-bio tent laminates are designed to perform with a variety of base structural models, including low-pressure and high-pressure inflatable systems, as well as metal, composite, and folding frames.

TurtleSkin Chem-Bio Materials: Lighter, More Durable Laminates
TurtleSkin laminates integrate chem-bio barrier protection while delivering the necessary properties of weight, flame resistance, weathering resistance, durability, packing volume, structural heat seal, and thermal management needed for collective protection structures.

Our engineering teams develop assembly methods and advanced fabrics for laminate walls, structural heat-seal tapes, flooring, load patch, thermal linings, and solar fly sheets. Warwick has optimized these chem-bio laminates to meet the challenging goals set by DTRA, JECP, and CBPS.

From initial engineering designs to full-scale production, Warwick offers a complete chem-bio materials solution for tent manufacturers.

System Mass
Reduced mass budget is critical to mission requirements. Among the development objectives for these chem-bio laminate materials is a 50% reduction of mass from existing, heavier two-layer systems, achieving a laminate of extremely low weight. Warwick's production specification for wall laminates mass is also very low.

Packing Volume
Integrated laminates must be designed to permit compact packing and ease of handling for the warfighter. Our chem-bio laminate materials offer our best combination of performance, flex, and packing efficiency.

Blackout / IR Signature / Thermal
Warwick provides a number of options for tent designers to address these three exacting parameters for soft-sided structures. In Option 1, improved functionality is obtained in a two-layer approach, incorporating a tent skin and a thermal liner. This provides improved durability and thermal management while maintaining flexibility.

Option 2 material integrates blackout and IR signature into a single laminate. This approach offers simplicity but forces compromises in bonding, thermal management, and system durability. The next level of performance is a three-ply system consisting of a solar fly, tent wall, and thermal liner.

This system is intended to significantly reduce thermal load with minimal increase in mass and packing volume, with the three layers working together to minimize solar and convective heat transfer to the tent enclosure.

Chem-Bio Laminates Designed for Durability
Fielding requirements of protective tents demand these laminate materials maintain their chemical and biological protection, tensile strength, and overall integrity throughout the life of the tent. Even after repetitive erecting and striking, decontamination, exposure to abrasion, UV and weathering, our chem-bio laminates are designed to resist pinholing, tearing, and delamination.

In addition to standard test methods, Warwick has developed new methods and apparatus to test laminate durability, including a dynamic sheer for stress and strain measurement, which our laminates have successfully completed past 100,000 cycles.

Laminate Interply Peel Strength
The integrity and durability of any chem-bio laminate is only as good as the interfacial strength of adhesion between each layer.

Unlike general purpose tent materials, an integrated chem-bio laminate consists of many different layers and needs to deliver high interply strength in order to support its specific operational requirements.

Warwick is a world leader in the development, engineering, and testing of adhesive systems for multilayer laminates.

In order to accommodate various tensile requirements, we have engineered a low-mass substrate using high strength yarns in combination with flame retardant in-fill fiber. This solution allows us to offer a substrate that delivers the highest tensile performance required.
