Paper Stronger Than Cast Iron

TaeKwonDood writes "All paper is made of cellulose, which at the nanoscale level is quite strong, but paper processing makes large, fragile fibers that break easily. Researchers in Sweden have have come up with a manufacturing process that keeps the fibers small, resulting in 'nanopaper' with over 1.6 times the tensile strength of cast iron (214 megapascals vs. 130 mPa). And since cellulose is the most abundant organic compound on the planet, it's cheap to use compared to other exotic, expensive-to-produce options — such as carbon nanotubes."

  14. Re:What is Tensile Strength by mrbluze · · Score: 5, Funny

    There seems to be some confusion about what tensile strength is. Tensile strength is how well a material can resist pulling, not bending or compression. Exactly, for example, ordinary toilet paper has poor tensile strength, resulting in many a brown finger for some. Let's hope this will stop with our new, stronger-than-steel paper. On the downside we may expect a few more red fingers.

    "Ever tried writing on iron? Not as easy... and folding it to put it in your pocket tends to be difficult."

    However, if you etch a piece of metal, you can use it as a stamp to create numerous copies of the etching, and when you hit severe writers block, its much easier to kill yourself with a piece of tin than paper cuts.

    214 megapascal (singular, it's a unit)

    Is that really a rule? Not one I was taught.

    After I ran 6.2 kilometer yesterday, I was feeling thirsty. So I drank 1.6 liter of water. It took 37 minute to walk back to my car. I fired it up, and saw that the engine was already 52 degree from sitting in the hot sun. I got home, and collapsed from exhaustion. I slept an entire 9 hour.

    Maybe it's a rule. I'd rather not sound like a fool though.
