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."

Re:Looks Familiar

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.

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.

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?

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.

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.
