 |
|
An Israeli company represented in NYC has developed an armor material that is made for personal hard body armor. Their prototype was was a Roman muscled cuirass. Its estimated to be able to absorb 250 tons of force per centimeter. That is not a typo either. Nor is it some weird magic fantasy delusion I had after watching too much Babylon 5.
Heres the link.

NANO-ARMOR:
PROTECTING THE SOLDIERS OF TOMORROW
An Israeli company has recently tested one of the most shock-resistant materials known to man. Five times stronger than steel and at least twice as strong as any impact-resistant material currently in use as protective gear, the new nano-based material is on its way to becoming the armor of the future.
--------------------------------------------------------------------------------

The discovery of the extraordinary wave-shock absorption quality of the IF materials, position it as one of the best candidates for future protective gear and armor.
A year ago IsraCast reported on the development of the first commercial nano-based lubricant which was developed by the Israeli company ApNano materials. A year later we find ApNano working also on a wholly different application of their technology - shielding and protection. In recent research lead by Prof. Yan Qiu Zhu of the School of Mechanical, Materials and Manufacturing Engineering at the University of Nottingham, England, a sample of the ApNano material was subjected to severe shocks generated by a steel projectile traveling at velocities of up to 1.5 km/second. The material withstood the shock pressures generated by the impacts of up to 250 tons per square centimeter. This is approximately equivalent to dropping four diesel locomotives onto an area the size of one’s fingernail. During the test the material proved to be so strong that after the impact the samples remained essentially identical compared to the original material. Additionally, a recent study by Prof. J. M. Martin from Ecole Centrale de Lyon in France tested the new material under isostatic pressure and found it to be stable up to at least 350 tons/cm2.
In the line of fire - creating super shock-resistant materials
Some of the equipment that's being used to produce the Inorganic Fullerene materials at ApNano's laboratories in Nes Ziona, Israel.
In order to understand how it is possible to create this ultra-strong shock absorbing material we first need to understand the nature of the nano material developed by ApNano. In the early 1990's the Nano-materials Synthesis Group in the Weizmann institute headed by Professor Reshef Tenne, ApNano Chief Scientific Advisor, and recent winner of the Materials Research Society medal, together with Dr. Menachem Genut, currently the President and CEO of ApNano Materials, Prof. Gary Hodes and Dr. Lev Margulis, discovered a new class of inorganic nanostructures. The group had found that certain inorganic compounds such as WS2, MoS2, TiS2 and NbS2 that normally occur as large flat platelets can be synthesized into much smaller nano-spheres and nano-tubes which they named inorganic fullerene-like nanostructures or IF for short. Fullerenes are a new form of carbon, other forms being diamond, graphite and coal. They are molecules composed entirely of carbon, taking the form of a hollow sphere, ellipsoid, or tube. Spherical fullerenes are sometimes called buckyballs, while cylindrical fullerenes are called buckytubes or nanotubes. Buckyballs are named after R. Buckminster Fuller, architect of the geodesic dome that he designed for the 1967 Montreal World Exhibition. IF materials are Fullerene-like materials but instead of being composed out of carbon they can be created from various other inorganic elements.
The "Onion like" nano-structure of the IF materials, is the result of a sophisticated manipulation on the original layered material. This unique structure is responsible for its remarkable strength and durability.
The new IF material produced by the Weizmann Group was made of Tungsten Disulfide (WS2). In contrast to organic Fullerenes, IF is easier and much less expensive to produce, it is chemically stable and is less reactive and consequently less flammable. Organic Fullerenes are also considered to be highly toxic while IF materials have been tested extensively and deemed safe. Tungsten Disulfide is relatively heavy and for that reason ApNano is currently experimenting with other materials such as Titanium Disulfide which is at least four times lighter and is expected to perform even better than Tungsten Disulfide against shock waves. One of the most interesting new IF properties discovered by ApNano is its extremely high degree of shock absorbing ability. Shock absorbing materials are commonly used in impact resistant applications such as ballistic protection personal body armor, bullet proof vests, vehicle armor, shields, helmets, and protective enclosures. The new Tungsten based IF material has up to twice the strength of the best impact resistant materials currently used in protective armor applications such as boron carbide and silicon carbide, and are over 5 times stronger than steel. It is also possible to combine IF with other substances in order to expand their range of capabilities. For instance, mixing IF with highly elastic materials can lead to new compounds which are both flexible and shock-absorbing. These properties position IF materials as one of the best candidates for future protective gear and armor.
Dr. Menachem Genut – ApNano's President and CEO, co-discoverer of the inorganic fullerenes.
Currently ApNano can manufacture only a few kilograms of the new material a day at their lab in Nes Ziona. In an interview by IsraCast, Dr. Menachem Genut, ApNano CEO, explained that the company is moving into semi-industrial manufacturing within the next six months producing between 100-200 kilograms of the material per day, gradually moving to full-scale industrial production by 2007, creating several tons each day. Although it is currently still hard to determine the exact price of the "nano-armor" when in full industrial production, given the cost of the original materials (Tungsten Disulfide, Titanium Disulfide, etc.) and the relatively low production costs, Dr. Genut stated that a kilogram of the new material will cost considerably less than a similar amount of the carbon-based Fullerenes. More field testing will need to be carried out before the nano-armor can be declared commercial but the company is optimistic that with some external financial backing it will be possible to have the first product ready in less then three years.

Thanks for the additional post Alex. Would have done it myself, but I wasn't sure whether it was against forum policy. Pretty cool huh. I've got to stop posting the techno stuff or people will start thinking I'm not a traditionalist.

Cool??? Hm... for one thing this will spark the development of new more penetrating projectiles too.
I personally think european renaissance nobility and the japanese shoguns were quite right in delaying fire-arms...
I KNOW it is impossible to turn back the clock but man is biologically better equiped to deal with horse-speed and cutting edge technology

Their PR department is doing its job well. None of their claims have been substantiated yet with field trials. All they have are extrapolations based on lab results.

Interesting!
However, I guess it's very uncomfortable to move in. Maybe they should have looked at gothic breastplates.
One last thing: how heavy is that thing? Didn't find any specs.

I have to agree with Dan Howard, sounds neat, but may we have some cold, hard test results? Also, after all the impressive numbers at the beginning, towards the end they do get to the point that for all this, at the end of the day one gets The new "Tungsten based IF material has up to twice the strength of the best impact resistant materials currently used in protective armor applications", so in a best case scenario one gets double the shock absorption, lower in most real world cases then I'd assume (since the highest number reported by PR could probably be safely assumed to be as good as it ever could get), which may have even less impact on the actual level of protection (it would seem to be reasonable that other factors want to have a say as well).
Still, nanotech does show a lot of promise, be it nanostructured materials or more exotic microstructures such as this.
As for the breastplate, wasn't the roman style breastplate just for illustration? "Illustration photo - medieval armor."

Yup, the photo is an el-cheapo Indian-made muscled cuirass, a pretty bad one, actually. Presumably that's not the new material's natural form! The lower cost and non-toxicity sound very promising, at least.
I've always had to laugh at Star Trek and similar shows every time a magnetic something clamps onto a hull or deck. A STEEL starship? "Where the heck are the carbon-fiber composites?" I ask! And here they are. I was right. Shoulda been a script writer.
