10x lighter than steel, but 500x stronger

TALLAHASSEE, Florida (AP) -- It's called "buckypaper" and looks a lot like ordinary carbon paper, but don't be fooled by the cute name or flimsy appearance. It could revolutionize the way everything from airplanes to TVs are made.
Florida State University researcher Ben Wang, whose computer screen shows a microscopic view of buckypaper.

Buckypaper is 10 times lighter but potentially 500 times stronger than steel when sheets of it are stacked and pressed together to form a composite. Unlike conventional composite materials, though, it conducts electricity like copper or silicon and disperses heat like steel or brass.

"All those things are what a lot of people in nanotechnology have been working toward as sort of Holy Grails," said Wade Adams, a scientist at Rice University.

That idea -- that there is great future promise for buckypaper and other derivatives of the ultra-tiny cylinders known as carbon nanotubes -- has been floated for years now. However, researchers at Florida State University say they have made important progress that may soon turn hype into reality.

Buckypaper is made from tube-shaped carbon molecules 50,000 times thinner than a human hair. Due to its unique properties, it is envisioned as a wondrous new material for light, energy-efficient aircraft and automobiles, more powerful computers, improved TV screens and many other products.

Can't wait to hear the UCI excuse on this one!

"Sir, at 400 grams your frame is too light for competition.  Please go back to riding your 1,000 gram Scott."

made of "bucky balls" of carbon atoms. at the molecular level these look kinda like soccer balls made of connectix or whatever.

i expect that aside from sorting out large scale manufacturing issues, the technical challenge for structural application will be their increased tendency to buckle in sheet compression due to thin/slender nature.

very interesting.

why is there a minumum weight rule i think for uci isn't it like 15. something lbs. or something like that?

6.8kg (or 14.99 pounds)

I believe it's there to keep the focus from being solely on who has the lightest bike

I woke up a cynic this morning.

Rant start.

The government will find a way to make them illegal or unobtainable to the everyday consumer for the governments own profit. Just like alternative fuel.

Rant over

In any case,  that is great and i would love to see it implemented in everyday use.  Can you imagine the wheelset that could be made?? Or laptops that weigh as much as a notebook of paper or less. That would be a wicked pissa'.

The material would be just as unobtainable as carbon fiber and titanium.  Both of those started life as aerospace materials and they were made into bike frames as soon as cost of production allowed.

The frame weight rule was put into place back when graphite frames were the rage.  This is before the carbon era (BC).  The rule was to prevent teams from compromising the saftey of the frame just to get the weight lower.  It's still a good rule...but the weight limit needs to be adjusted to acount for new frame materials and design.

Seems to me that weight of the frame should not be the deciding factor when measuring safety. There must be a better metric for safety that is not material dependent. Stiffness or something.

I don't think stiffness would work. You would need to find a metric for overall damage tolerance. This would be hard, especially given the variables associated with riding conditions.

Philosophically, there should be a way to promote safety without regulating progress in technology; however, a pragmatic solution is a weight limit that is revisited and changed over time.

I would imagine that the good folks that do automotive crash testing would have some good metrics defined.
