Well, might as well start this off by mentioning my sci-project.
What I'm going to be doing is injecting a resin into balsa wood.
The balsa wood is placed inside a vacuum bag, a vacuum pump is turned on, which sucks out all of the air and moisture from the wood, leaving only it's cellulose structure.

A valve is then opened which allows the resin to flow into the bag, where it is then pulled into the wood by osmosis. Or smth like that, I've forgotten the mechanics.

Anywho, I'm going to compare the strength of the infused wood to just the normal wood.

I'm using resins consisting of 0.1 percent concentration of SWCNT's, 0.5, 1, and a whopping 20 percent.

Oh yes, I've forgotten to mention the fact that one gram of carbon-nanotubes is worth 10,000 USD.

Spiffy.

good luck ammassing that kind of money

this theory sounds interesting.

what will you use to check the hardness?

I assume he will be testing the breaking point, if I were to do this experiment, I would have the wood anchored at on end and put a fulcrum underneath the middle, I would then gradually ad weight to the other end and record the weight at which it snaps. Using the recorded weight and the known length from the weights to the fulcrum, he can then work out the stress involved.
At least thats how I think you would do it, its been a while since I did experiments like that.

ok.... at least i know now that i will have to save money for a LONG time before being able to buy a knife or a katana in nanotube

more seriously (though i really want a cnt blade :P ), did you start your project or not yet ???
because you already mentionned it some time ago in the 1st thread, but didn't had started then

I'm pretty sure he's saying he's gonna MAKE the nanotubes, not buy them...

**Ishman** · 01-31-2006, 04:47 PM

Uh...
No way in hell could someone without an income could buy em, and their restricted by the government as to who can get them.

I just happen to know the right people, so, I'm getting the stuff as a donation.
Since it'd be illegal for me to obtain some in pretty much any other way.

Anywho, that's the VALUE of the carbon nano-tubes.

They don't actually cost 10,000 USD to make a gram. Sorta like the diamond industry in that respect...

Anyways, I'm going to be starting it in a few days as soon as I get a resin, or, as I'm pretty sure what's happening now, I'm getting pre-infused samples of balsa wood.

And aye, I'm doing it the way gvaz said, but, just so yall know, it's a horrible method of determing the strength of a wood, since a rather large study done by... uh... can't remeber, shows that the only reliable method of judging a wood's strength is by pushing a rounded spike through it, and measure the force required.

Cough cough.
(Gvaz didn't even give the method, he asked for it.)

Meh.
I'm bad with names.

Huh... what's your thought's on the new Navy trimerene [sp] ship, the one equipped with coilguns, or railguns, I forget which, anyway, the completely electrice ones.

Which just makes you realize that they're perfect sitting ducks for nuclear airbursts... [I.e. EMP blasts]

Pictures, details and web pages please.

yep^^
but i'm skeptic over electronical stuff... i hope it's well done and securised, but imagine if a spy or a stupid dick put a virus in the computer system...

:P
also, electronics + water doesn't seem to match well generally
