Nanotube Body Armor Coming Soon

s31523 writes "Military and law enforcement agencies are constantly seeking better protection in the line of fire, but current armor is heavy and bulky. The University of Cambridge has developed a new type of carbon fiber made up of nanotubes that is some cases exceeds the performance of Kevlar. The new material has other potential uses as well, from bomb disposal bins to flexible solar panels."

[Anonymous Coward]

can you make better internets out of these tubes?

Re:but

[Nullav]

Actually, according to TFA, networks can indeed be made using a series of tubes.

But the new material could also find applications in the area of hi-tech "smart" clothing, bomb-proof refuse bins, flexible solar panels, and, eventually, as a replacement for copper wire in transmitting electrical power and signals.

I could really see a use for such a resilient material in the more earthquake-prone areas, as opposed to fiber which would probably snap in a lot of situations.

One of my fellow students in university (I have a physics degree, he had double major physics, applied math, followed with MSc (Physics), PhD Math, a fairly bright guy ;) ), anyways, his PhD thesis was solving electron quantum states in carbon nano-tubes. Properties he mentioned were, they are superconducting in one direction, and have total internal reflection (what causes fiber optics to be useful). So yes they will make a better internet. They also could make better electronics in general (no resistance = electrons moving as fast as they possibly can with the applied voltage).

Looks Familiar

[DumbSwede]

I know it's inevitable and I want our troops protected, but its ironic how much this looks like the garb worn by the enforcer types in dozens of dystopia movies. One key to waging war is to dehumanize the enemy in the eyes or your citizens and fighting force. It will be far easier for our adversaries to paint our troops as inhuman.

Re:Looks Familiar

[rastilin]

It doesn't look any different from the armour already worn by SWAT teams. The only real difference between this and the normal soldier's armour, to me at least, is the face plate. You could remove that if you were ok with shrapnel in the eyes.

Exactly.

Enforcer types from dystopias, just like the GPP said.

They're just fitting in with the modern trend. In the time I've lived here in Cambridge, the average police uniform has gone from the friendly, lots-of-white Police Service garb to the almost-all-black Police Force look of today. This has, of course, been happening in parallel with the systematic erosion of individual rights and increases in summary powers for the police, all with the backing of both our national government and, in some cases, our local councils. It would be sadly ironic if police officers became even more invulnerable^Wisolated due to an invention from our very own university.

The motorcycle style helmet does hint at "low budget dystopias" though.

Re:Looks Familiar

[Loke the Dog]

True, and there's more to it. Inhuman beings are more frightening than humans, and if you feel inhuman, you will not feel a need to act like one.

Re:Looks Familiar

[vertinox]

It will be far easier for our adversaries to paint our troops as inhuman.

That may have benefits as well. Would you shoot something that doesn't look human and you aren't entirely sure they are going to die? If the enemy appeared to be immortal cyborgs that your (apparently) puny weapons had no affect on, would you not just be afraid of them and comply?

Re:Looks Familiar

[Anomolous Cowturd]

Your troops are enforcer types in a dystopian reality. While I'm always thrilled to see advances in materials science, and happy to see people that little bit safer, if your troops just stayed home we could use their armor for solar panels and I'd be even happier.

Yes, because an all-white uniform is so much friendlier.

Pointless

[Kamrom]

Why develop new body armor, when our soldiers still can't get the stuff made several years ago?

Re:Pointless

[hey!]

For one thing, because it simply isn't true that we can't get it to them. We just can't supply them at the rate we ought to at the price we are willing to pay. It boils down to the fact that the number of lives saved isn't worth it to the US taxpayer, or at least the ones that vote.

For another, just because it is "got to them" doesn't mean it stays got. Every time a ceramic armor plate takes a bullet, it ought to be replaced. Even just being knocked around can probably weaken the armor. Durability is the reason the flexible glued ceramic disk armor might not be the best choice for an environment like Iraq.

For yet another, fabric based armor makes it possible to protect areas that you can't with ceramic armor: the hands, the head. There was a report on NRP about the unusual number of fatalities suffered by police this year. The bad guys have adjusted to the fact that the police wear body armor and take a head shot before the cop realizes he needs to draw his gun.

Finally, production of fabric armor an probably be scaled more cheaply than ceramic plates. You start with a vat of organic goo, draw threads out of it, spin them into thread and weave them into garments. You can make as large a "plate" as you need by setting up long warp yarns and weaving a longer strip of cloth. Think of a set of drapes: you could produce armored drapes if you wanted to. By contrast with ceramic you have to fire each plate in an oven. To make a larger plate, you need a larger oven and presumably getting a uniform result is trickier. To ramp up the production line, you need more or larger ovens. To overcome these problems, you could make lots of small plates, but then joining them becomes a problem.

If you could make fabric armor that was just as good a ceramic plate armor (doubtful, but imagine that you could), it is certain to be cheaper and faster to produce, provided you are making enough.

Most taxpayers are already paying for the war and associated expenses. I suspect many would be not displeased to put money into actually saving troops rather than (to pick a couple of examples) paying mercenary armies who don't pay their own taxes, or paying corrupt contractors building the US embassy with (semi-)slave labor, or paying the CIA to run secret prisons where they can torture with impunity, or paying Haliburton so Cheney can make a profit.

Bomb disposal bins

[wlad]

...so that's where they dispose of used bombs?

Sooo...

[Fred_A]

Will it blend ?

Wearing enough

[Strange Ranger]

No matter the material, body armor only works when you wear enough of it.

http://www.nytimes.com/2006/01/07/politics/07armor.html

Almost from the beginning, some soldiers asked for additional protection to stop bullets from slicing through their sides. In the fall of 2003, when troops began hanging their crotch protectors under their arms, the Army's Rapid Equipping Force shipped several hundred plates to protect their sides and shoulders. Individual soldiers and units continued to buy their own sets.

And a year and a half later (after above article):

Health Concerns

[failedlogic]

Might there not be a health concern/issues with nanotube or nano-anything (yes that was technical!), being used? Their structures are so small our immune systems can't block it and it might adhere to cell walls more than we
'd ever want to. Wearing such body armor, which would stop speeding bullets, IEDs, mines, rockets from injuring soldiers might not be a good idea. The injury from the enemy fire might not be the only concern.

No need for nanotubes.

[muttoj]

nano tubes will in some cases exceed the performance of Kevlar. New existing materials as Dyneema and Taeki5 already exceed the performance of kevlar by a long shot.

I Call Bullshit

[TheThirdRider]

Or at least partial BS. I work at a nanotube R&D lab and one of the things we're working on (which I am personally involved with) is making carbon nanotube thread. I've read over and discussed the very paper that is mentioned in the article; also I've looked at what the University of Texas at Dallas is doing. Pulling SWCNTs (single walled carbon nanotubes) from a furnace does not create the same level strength due to the tight wrapping of CNTs as using van der Waals forces present in aligned MWCNTs (multi walled carbon nanotubes) when pulling thread from an aligned forest of nanotubes. While the individual tubes are stringer than almost anything, they do not adhere well to each other and tend to slide apart when in a rope. C They may have some fibers that are stronger than Kevlar, I've made some myself infact. But it was only that strong in comparison when measuring Young's modulus because it was so small as to be neutrally buoyant in air and nearly invisible to the human eye. And, unfortunately, so far that strength doesn't scale. So, yes they probably have made super fibers, but I highly doubt they are usable for the applications they are claiming.

Re:multiple uses?

[Entropius]

Think the army is actually going to make 200k suits of this stuff?

A better way to stop people from getting shot in wartime is to not be in stupid wars.

Why keep repeating this meme?

[Soulfader]

Everyone has at least an Interceptor vest. No American service member goes overseas without one. I'm in the National Guard, and even us bastard red-headed stepchildren of the war effort get full IBAs with the side plates and shoulder shrapnel protection--more armor than most of us want or need.

(More on the IBA.)

Yes, there are newer and better things out there. And many troops are wearing them already--or were when I was in Afghanistan last year. Presumably more have them now. Could they get the newer and better stuff to the troops faster? Perhaps. Look into it. Make a valid argument. But stop trotting out the old "troops can't get any armor" BS.
