New superdense wood could replace steel

[~~whimsy~~]

Newly fabricated superstrong lumber gives a whole new meaning to “hardwood.”

This ultracompact wood, described in the Feb. 8 Nature, is created by boiling a wood block in a water-based solution of sodium hydroxide and sodium sulfite. The chemicals partially strip the wood of substances called lignin and hemicellulose, which help give wood its structure and rigidity. Then the block gets squeezed between metal plates heated to 100° Celsius at a pressure of 5 megapascals — about 50 times the pressure of sea-level atmosphere. That squashes the gaps between the cell walls in the wood, shrinking the block to about 20 percent its original thickness and making it three times denser.


Researchers found that the densified wood could withstand being stretched or pulled 11.5 times harder than its natural counterpart without breaking. That makes it about as strong as steel, even though it’s more lightweight. Stainless steel pellets fired from an air gun and moving at 30 meters per second easily busted through a typical wooden plank, but got lodged in a stack of densified wood sheets with the same total thickness.

Interesting. I don't know about having a car though.

But can jet fuel melt/burn it?

Bu replacing steel with that new ultradense wood would mean we would harvest even more wood than we already do, right ? Do we really want to do that ?

That's what I was thinking. But it's not like this will be implemented overnight and replace every structure and/or vehicle in a 10 year plan. I say it'd be okay as safety features on cars and trains. Load bearing beams for buildings. If it ever happens

"superdense wood".....on a porn site.....and nobody made a dick joke?

Wow.

I thought so too. This board changed not for the better

This is what happens when BlueBalls, AndronicusRy (whatever his new sn is) or StanScratch and LurkingDirk isn't around anymore.

Super dense person thought this up.

:tongue:

We need more trees.

I wonder if it makes a good tone wood for guitars? Any pics of how it looks sanded, and stained? I wonder how the grain looks.

If not the entire car, what about wood paneling on the sides? If only for the aesthetics?
