Armor Holdings, Inc. Announces Exclusive License Agreement for New 'Flexible Armor' Technology
Friday February 24, 7:30 am ET
Will Be Applied to Body Armor and Other Personal Protective Products


JACKSONVILLE, Fla., Feb. 24 /PRNewswire-FirstCall/ -- Armor Holdings (NYSE: AH - News), a leading manufacturer of security products and vehicle armor systems serving military, law enforcement, homeland security and commercial markets, announced today that it has been selected as an exclusive licensee for a unique application of nanotechnology, currently referred to as shear thickening fluid (STF), that has the ability to enhance the performance of ballistic fabrics and protective armor products. Developed by the University of Delaware's Center for Composite Materials, in partnership with the Weapons and Materials Research Directorate of the U.S. Army Research Laboratory, testing has indicated that the technology appears to allow conventional ballistic fabrics to increase the level and quality of protection they provide without compromising their weight, comfort or flexibility.
Under active development for the past five years, STFs are special materials with nano-particles that exhibit properties normally associated with both solids and liquids, but are rarely found in the same material. Sometimes referred to as "liquid armor," the material is actually a nanotechnology that exists in a flexible, fluid-like state under normal conditions but adopts seemingly rigid qualities and becomes less penetrable when impacted. As a result, this special material can be applied to conventional ballistic fabrics or other materials used in armor applications, allowing them to remain flexible under normal wear, but simultaneously becoming resistant to penetration when impacted by a spike, knife or high velocity projectile or fragment. STF treated fabrics effectively spread the energy over a larger area.

Dr. Tony Russell, Chief Technology Officer for Armor Holdings, Inc., said, "Going back to the Middle Ages, developing armor has involved a constant balance between the need for protection and the need for comfort, flexibility and light weight. Rarely do the words 'flexible' and 'armor' get used in the same sentence, but this new technology has the potential to unlock entirely new and better solutions that will leapfrog to the next generation of armor and other lifesaving equipment. The scientists at both ARL and UDTC have done an outstanding job of creating the core technology and demonstrating its advantages. We are proud to have been selected to assume development responsibility for this important technology and we look forward to rapidly fielding products that will help better protect those who operate in harm's way. This represents an important new addition to the Armor Holdings portfolio of core technologies and further allows us to select and apply the best material for each application."

Extensive testing conducted by UDTC and ARL has demonstrated that when treated with STFs, a conventional ballistic fabric can resist penetration from an ice pick that would otherwise easily penetrate the fabric. However, further testing and applications in the field may be needed to understand fully the properties of STFs. In addition, fabrics treated with STF have been shown to reduce "back face deformation" (an indication of blunt trauma) from high energy ballistic impacts. Importantly, treating the fabric with this material has little or no effect on the look, feel, texture, weight or flexibility of the fabric.

Armor Holdings, which will be the sole commercial provider of this technology in applications related to body armor vests and extremity protection, helmets and gloves for protective use worldwide, anticipates fielding the first products later this year.

Professor Norman Wagner of the University of Delaware and Dr. Eric Wetzel of the Army Research Lab, commented, "This has been an extremely successful collaboration between ARL and UDTC and we believe this technology has the potential to yield new and valuable products that will provide better protection to those who need it. Armor Holdings has a proven ability to take technologies, such as this, improve upon them and rapidly develop them into products that can be used in the marketplace. Dozens of dedicated researchers contributed to this project over the past several years and we look forward to seeing the results of their work being used to help save and protect lives."

Robert Schiller, President of Armor Holdings, Inc., said, "This is a very important development for Armor Holdings and underscores our leadership in the area of developing life safety and survivability systems for members of the armed forces, law enforcement and correction officers and private citizens. We are constantly striving to develop new and better ways to protect those who protect us. In the past two years, we have fully integrated the R&D capabilities across our various businesses, allowing us to seamlessly adopt the use of technologies such as STF in a wide range of protective applications."

The potential applications of STF include a wide range of products such as body armor, vehicle armor, helmets, gloves and bomb blankets to protect soldiers, law enforcement, corrections and government officials and other industrial safety applications. Armor Holdings has selected Barrday Inc. as a partner for development and production of STF-based ballistic fabrics. Barrday has strong complimentary experience in weaving fabrics from high strength fibers as well as applying films, resins, finishes and coatings for both soft and hard armor applications.

Background on Shear Thickening Fluid

Under the direction of Professor Norman Wagner, the University of Delaware, Center for Composite Materials began investigating shear thickening fluids in the mid 1990s. Beginning in 2000, UD CCM began working in partnership with the Army Research Lab's Materials Research, led by Dr. Eric Wetzel, to create a new armor material. The first promising ballistic results were achieved in 2002, presented publicly at the U.S. Army Science Conference in Orlando, FL, in 2002. The U.S. Army recognized the significance of this new technology by awarding the UD/ARL research team the Siple Award as the best paper at the 23rd Army Research Conference in December 2002. Work on the technology continued throughout 2003 and 2004, with important discoveries of the stab and puncture resistance of the fabric and further refinements in processing and fabrication. A U.S. patent application was filed in May of 2003.

Interesting. Combining this with the "dragonscale" ceramic plates would make for quite strong armor.
 
A friend who commuted by motorcycle had a full body suit with some sort of pads at the joints that sounds very similar to this. Soft and flexible, but if you smacked it sharply it felt hard. Let's hope it works.
 
Justin, I thought the same thing.


Feels like gritty jello, protects like a stack of telephone books.
 
"These things, too shall come to pass..."
Interesting how much of science fiction has become science fact.
Excuse me, I have a pizza to deliverate. :D
 
The movement is headed towards a new age of superior body armor. Ultimately rendering our small arms more and more ineffective. Our enemies are adopting a doctrine of armor-piercing for their small arms. Being that we are banned from owning any armor piercing ammunition due to all modern innovation in AP being made for cartridges illegal for us to own, as well as being reserved for LE/Mil or import banned. We will be left behind in the dust.


Watch and see. The key for defeating future armor sits in the past.


.45-70.


Sure ballistic plates can stop the .45-70, but what will stop the ballistic plates? :evil:

No matter what fancy inventions they come up with, there is no getting around the fundamental issue of FOOT-LBS. Something has to absorb it.
 
I don’t know enough about it to call it a fake, but I’m more than a little skeptical. This sounds like the emperor’s new body armor, and/or the clear coat and fabric protection the new car dealers try to sell you. These guys will sell you a miracle liquid you spray on you existing body armor and it makes it super-more-better. Maybe so, but I’ll believe it when I see independent tests.
 
Level IIIA made with newer-technology materials (shear-thickening fluids, synthetic spider silk, or carbon nanotubes) will still be rated for the same projectiles as any other NIJ Level IIIA vest. It'll just be lighter and more flexible, but Level II is Level II, Level IIIA is Level IIIA, etc.

Technological improvements may allow concealable Level III armor to be made practical, but it'll provide the same protection as any other Level III. It's not the protection level that's changing, it's the wearability of the higher levels of protection that is improving.
 
WE were just shown some new pads for hockey that must use similar material. flexible and soft on the body, but when hit with a baseball bat it becomes ridgid and stiff. wjill be the next new thing stuff you do not have to break in, but protcts like steel.
 
I may be wrong about this, but I believe that the American Olympic ski team uses this technology in the "spandex" suits they wore in this olympics. Not sure, but I did notice the Americans were no longer wearing the bulky shin and elbow / hand protectors that many of the other countries were still utilizing. Anyone else heard this?

Hmm... pre ww1 ish, we were using big fast bullets to penetrate cover and hit people at long range.
Then the higher up's discoverd we didnt need all that penetration, nor the long range. By korea and vietnam, we downscaled to carbine sized weapons which chould still punch through at the more common fighting distances.

I suspect we will just go back to the older weapons once this stuff becomes commonplace.
 
Some questions-

How heavy is this stuff going to be for a trooper in the field?
Also, how is it going to be contained in a vest?
What happens when the vest is punctured by a bit of shrapnel and all the goo runs out?

This is an interesting idea, but unless it is a lot lighter than water, it's not going to be very practical in full-body vests. Trauma plates perhaps, as well as a thin cover for helmets...

Don't Tread on Me- my thoughts exactly, vis-a-vis bigger bullets. On the other hand, current vest technology is readily available to the public in most civilized areas of the US, so I'm not sure about your worries.
 
Since firearms are always gonna have velocity...you'll have to beat it with a faster, pointy(er) bullet than it is rated for. At extreme close range a knife will get it done. I know the article said it stops knives, but it works based on impact. Slow the velocity down. An example, stomp the guys knee out to get him on his back and put your knife over his heart and apply body weight. Of course, you could just pick an exposed target too.

With icepicks, I would be curious if there is a stabbing type velocity slow enough to penetrate and not make it stiff. The sharper the item, the less surface area to create the needed "impact".
 
Sounds interesting, but I'll be surprised if the technology is mature enough for deployment anytime soon.

The general tone of the announcement sort of reminds me of the original hype that accompanied the supposed introduction of Black Rhino ammo some years back.
