Its the same thing as Carbon fiber but insted of using graphite fiber it uses buckyball tubes.

Working with a material 10 times lighter than steel - but 250 times stronger - would be a dream come true for any engineer. If this material also had amazing properties that made it highly conductive of heat and electricity, it would start to sound like something out of a science fiction novel.

Now that's not such a good property for body armor....

I remember buckballs when they were being researched - didn't the c60 get into people's lungs and cause inflammation akin to asbestosis?

How'd they fix that?

It isn't bucky balls, it is carbon nanotubes which discovery was made possible by the discovery of buckyballs.

Wood smoke has natural buckyballs in it BTW.

PS, if it is electrically conductive and you need it to not be, cover it with an insulator. That is a problem easily solved.

Folks, this is essentially a sheet of flexible diamond, think of how this will revolutionize life.

Carbon nanotubes are far stronger than Carbon Fiber.

I'll take heavy barrels, if you don't mind, they help dampen recoil.

But a Suppressor made out of that stuff would be interesting.
The way they talk about the way it dissipates heat would make for some very light, very strong, very cool (literally) sound suppressors.

Materials like this are the sort of things we need to develop in order for us to leave this planet and colonize others. And I think that they will lead to exactly that.

Actually, thermal conductivity in armor would be a good thing as thermal conduction means energy dissipation. That's good if you have a lot of kinetic energy that needs to be dissipated as heat.

Works both ways, CN body armor would radiate body heat, unlike Kevlar which insulates. It would be more comfortable to wear. As long as you put a layer of some kind of cover fabric to keep the sun off the armor panels that is.

Did you see this?

Because it has an unusually high current-carrying capacity, a film made from buckypaper could be applied to the exteriors of airplanes. Lightning strikes then would flow around the plane and dissipate without causing damage

Good by EMP! It was nice knowing ya...

The Luddites who dream about the EMP bomb wipeing out modern civilization must be severely disappointed.

True, this will help make space exploration and explotion less costly and safer. It will still affect many, many more everyday mundane things.

We are on the cusp of a revolution in materials science like we were with semiconductors in the early 60's

Imagine body armor with active cooling and the carbon nanatube armor plate doubling as a heat sink.

So where can I buy a few sheets????

Do you need a Buckypaper saw to cut it to size, if so, add one to my order!

You hit on something with the knives.

#1 safety warning with all the variations of "Buckeypaper" or CN fabric so far.

WATCH THE EDGES

You get the paper cut from hell, they tend to be very thin and very sharp.

Oddly enough other than as a safety notice, the sharp edges get no press compared to the other features.

Why don't we just use cheap industrial diamonds, crush 'em up into a mixture, and form them into inserts for vests?

Been tried, and the end result was not very impressive. Cracks between the diamond crystals.

If you could make a plate that WAS a single diamond you might have something.

CN has most of diamonds properties, but is a lot easier to fabricate things from.

Crushed diamond paste does not have the property of great tensile strenght (Like Kevlar). Carbon nanotube sheets have the greatest tensile strength of any material yet known.

My guess is that it is very expensive, but I'm sure that they are researching how to manufacture it as inexpensively as possible.

Theoretically CN should be fairly inexpensive- its carbon after all. The rest of the process is energy and various solvents, most of the solvents can be recycled. Its very expensive right now because its so new that no one knows how to manufacture high quality tubes in quantity-much less actually possess the machenery to do it yet. There is some hesitation from the fact that techniques are changing so rapidly that investors are afraid to comitt to a technique only to have someone turn around the next week and obsolete it.

Another problem is that with the existing processes for making CN feed stock you dont get just ONE kind of CN fiber. There are single wall (SWNT) and multi-wall (tube in a tube, MWNT) and then in each kind there are at least three different "twists" to the arrangement of the buckyballs in the tube walls. Each has different properties, but they are all so close to each other in size and weight they are difficult to seperate.

Another advantage of heat dissipation would solve one of the major problems with body armor-over-heating the wearer. You'd be more comfortable with a higher level of protection in hot weather.

Also pay attention to the Space Elevator mentioned above. You probably have no concept of how that would revolutionize space travel and exploration, as well as life here on earth. The benefits would be hard to overstate.

Instead of calculating dollars per pound of materials rationed into space for a supplying an exploratory mission, you could transfer almost unlimited quantities of raw materials, water, fuel, structural components etc. into orbit which could then be put into flight without expending most of your fuel just getting tiny amounts off the earth. Mission planners would not be nearly as excited about finding water or other esentials on the moon or mars because that becomes much less important when it is easy and economical to take what you need with you from Earth.

Or, transfer all the building materials you need up the elevator and build an orbiting research center, hotel, city for the handicapped, rest home, hospital-all the benefits of earth a short shuttle and elevator ride away.

Thats what Im talkin' bout!

I always figured the darn things to be more slim, and not so bulky......

How about using buckypaper to line Nuclear power plants to help contain everything, or little boxes they could put over potential IEDs to contain them in a more safe fashion? Can I get a replacement hip out of one? And my darn coat hangers would never bend again I tell you!

A company already exists to build a space elevator.

They are already doing balloon tests of the climber that will run the CN ribbon up and down the original line lowered from space to build up the bridge, in a manner similar to stringing the cables on a suspension bridge.

I'm personally thinking of its possible use in aircraft and sportscars. Imagine the thrust to weight ratio of an aircraft made out of "Buckeypaper". The fuselage would be siginificantly lighter, not to mention stronger. UAVs and missiles could be more manueverable than ever because they could withstand much higher G-forces.

Imagine a sportscar made out of this stuff. It would be incredibly strong, and require significantly less power to make it go very fast. Not to mention that the stuff should theoretically be cheap to manufacture. This stuff's got alot of potential. (and didn't I just read about some "transparent aluminum" stuff within the last couple of days?) The world is seeming to become more and more like a science fiction movie.

That would take a LOT of CN, graphite is a ok neutron absorber-it was used in the very first fission piles- but concrete, or steel for moveable reactors is still probably better

, or little boxes they could put over potential IEDs to contain them in a more safe fashion?

Define little? But yes that would work in some cases.

Can I get a replacement hip out of one?

Maybe, I am not sure about how CN reacts with the body, most other carbon compounds the body tends to absorb, on the other hand the body at least doesn't reject carbon. CN is being used in experiments to make artifical muscle.

And my darn coat hangers would never bend again I tell you!

Actually they would bend, but they would bounce right back to the way they were shaped.

No it ain't, and that's a good thing. Diamond is amazingly scratch-resistant and hard, but brittle as anything. That's how you can cut such nice shapes out of it. This is better than diamond, if the hype is true.

Kevlar does not approach the tensile strength of CN. and the diamond would proabally badly abrade the Kevlar fibers.
