NEW EXPLOSION-PROTECTION FABRIC REDUCES BLAST SHOCK 25 PERCENT
HOUSTON, June 22, 2010—ZetixTM, a revolutionary new blast-mitigation fabric marketed by
Houston-based Advanced Fabric Technologies (AFT), has been shown to reduce the shock
wave associated with an explosion by 25 percent, according to researchers at the University of
Exeter in the United Kingdom (UK).
Zetix was developed initially as a blast-curtain material, designed to catch flying
window glass and other debris, but the Exeter test findings indicate it can substantially reduce
the shock wave that is the primary cause of death and injury in an explosion.
“Zetix, based on patented auxetic technology, represents a completely new approach to
blast mitigation because the material automatically adjusts its strength and thickness in
response to the application of explosive and other forces,” said AFT President David O’Keefe.
Zetix employs an elastic yarn wrapped in non-elastic fibers that cause the yarn to bulge
instead of thinning when stretched. Bundles of these wrapped fibers are woven together into a
fabric that may be interwoven with fiber optics, telemetry wires and other materials to provide
additional capabilities, O’Keefe noted.
Tests conducted through the UK’s Ministry of Defense revealed that a single layer of
Zetix rendered shrapnel from a rocket-propelled grenade (RPG) detonation from a distance of
1.5 meters (five feet) non-lethal. In another such test, one layer of Zetix survived eight
consecutive grenade blasts from a distance of one meter (three feet). Testing is under way in
the United States by AFT and potential end-users in a variety of industries.
“Security applications for Zetix include lightweight armor enhancements for combat
vehicles, aircraft and ships; spall liners; blast curtains; bomb blankets; and even bullet-proof
vests, when employed behind ceramic strike plates,” O’Keefe said. “Other applications include
hurricane protection for refineries and offshore oil and gas facilities, self-adjusting filters,
injury-reducing seat belts, and medical materials.”
Zetix was invented by Dr. Patrick Hook and associates at Exeter, in conjunction with
Dow Corning, Ltd. Advanced Fabric Technologies holds the exclusive right to manufacture and
market Zetix in the Western Hemisphere and first right of refusal for international marketing.
Exeter’s “Auxetic Textiles for Blast Mitigation” project is being funded to the tune of over half a
million British pounds (US$814,000) for three years, through July 2011.
