To prove the strength you should have done a weighted stress test on a new length of carbon nano tube prior to chopping with the axe and after. This would have been a more scientifically proven result and allowed to see exactly how much if any loss of strength occurs as a result of chopping the length with the axe.
Except it was neither scientific nor a weighted stress test. It was a short 2 minute video to see if it would split in two by the swing of a small axe.
Hello AtHomeScience, The thickness or diameter used in this video is 300 um. We do not produce our CNT's but rather source them from qualified suppliers.
Sold. I bought a 50-dollar sample. Waiting on shipping. I build custom 250-gram FPV helicopters for dive bombing practices, and motor manufacturers (all in China and out of our control) often make motors of this weight class with a factory pressure fitting shaft without bolting for shaft swaps. I have been using Kevlar threads as fitting inserts to allow my own custom shaft to be installed in the motors, but Kevlar often breaks during the pressure insertion procedure unless I polish the shaft very laborously and neatly. Now I have this magic insert that can take some abuses. My drone's diving videos are in my channel.
I tried scissors today. I bought a 5 yard sample from Dexmat. And the carbon nano threads are so thin and slippery, they just slip in between the scissoring blades, even when the thread is under good tension. It took strong tension and repeated scissoring, about 10 times, to fully sever it. The same pair of office scissors cut clean Kevlar strings with single scissoring every time without exception. This Dexmat product is not a textile product when you handle it. It is more slippery than anything you experience.
Experiment with equal weight of string, chopping with the axe on a mechanical wheel raised to the same height and falling by itself. Also do tensile strength tests at different temperatures and humidities.
Carbon nanotube yarn is not just multiple strands of nanotubes woven together. Its a mixture of epoxy and nanotubes, reducing its strength. Reason: Its very hard to make long strands of carbon nanotubes
Thanks for the question! At the moment we have two ways to apply insulation to our yarns and braids: - for short lengths we can apply heat shrink tubing - for longer samples we are able to put a braid of nylon thread around the yarn Neither one of these is a standard option available on our online store, but we can do it in some cases by special request. There are other ways that we could apply insulation to this material, such as extruding polymer or rubber around it, but we don't have the capabilities to do that yet; we are still operating at a small scale, so that's just a matter of not having the proper equipment.
I have seen a CNT reinforced suit, Negate the kinetic impact of a .357 revolver. What does this mean? It means that not only did the round not penetrate the garment, The force of the blow was distributed across the apparel... Think about what this means
Looks impressive but you guys need to better standardize testing. You need to control test material length and tension. Also the force of the axe (preferably with an Instron machine), sharpness of the axe and the cutting surface
Carbon nanotube, the true actual stuff, is never cut. It can be reduced in size by shearing it off eachother, but the actual tubes, are never destroyed after creation.
Paul Bunyan he ain't. His hatchet strikes remind me of the vicious blows you see on championship wrestling, especially when striking the carbon nanotube.
Goodness you guys need to work on production value but nice job on the concept. This is great when you want to explain just how awesome CNT applications are.
Why not make carbon nanotube fiber similar to carbon fiber witch you can use to create solid material jhust with carbon nanotubes instead Of jhust carbon?
It is difficult to create that much fast enough to use in production. It takes months with good planning to produce enough for that string. Each tube is a fraction of 1 centimeter.
This is stupid, use a harder surface behind it" then your TALKING. Or even securing it on both sides and then striking the nano tube yarn in mid air so the nano tube absorbs the full impact of the axe.
I have an idea! Let me put a thin piece of wood on a countertop and smash it with an axe! The wood won't break or anything and then I can feel comfortable smashing the string as hard as i can without breaking the countertop, the axe, or my hand! 😂

What is that kevlar stuff?? By the way it was awesome to see nanotubes in action✌🙄
Does it make a good guitar string?

No. And if it was the expense would be great. Production has been government limited due to the danger of weaponization.
Good Change to chop with line of axe edge perpendicular to the grain of the wood
do you have any capabilities to apply a isolation to this ???

Potent material. Underrated.
Maybe try smashing the same spot several times?
What about fire ?
Fire destroys the lamination, but the tube's survive up to 4,000 C

Looks impressive but you guys need to better standardize testing.
You need to control test material length and tension. Also the force of the axe (preferably with an Instron machine), sharpness of the axe and the cutting surface
there are any number of yootoob vids on how to use an axe properly.
So, how d o you cut it easily? How about the fabric form of this stuff, will scissors cut it?
Carbon nanotube, the true actual stuff, is never cut. It can be reduced in size by shearing it off eachother, but the actual tubes, are never destroyed after creation.
Wood is pretty soft. What if you lay it down on something like granite?
You'd break the are probably
I think it may have dulled your ax? You should try chopping it on concrete or steel. That would really be impressive.
The tube might shatter apart of the laminate structure, but the actual tube's would survive no problem.
Revolutionary
How did you cut it to begin with?
What sorcery is this
You've killed the table for a video clip. Oh well, sometimes investments have to be made!
So how do you cut it, a torch?
Try doing that with lab grown spider silk, it’s bulletproof.
CNT>lab silk.

Paul Bunyan he ain't. His hatchet strikes remind me of the vicious blows you see on championship wrestling, especially when striking the carbon nanotube.
Can you burn it till it's gone?
But how does the tensile strength of cnn compare with kevlar?
Thousands times stronger. Million times stronger than steal. The fiber will delaminate before breaking apart.
Just after the explanation I knew the wood was oriented in the wrong way.
We're can I buy the nano string

What is the average length of nanotube in the yarn?
Fractions of a centimeter are woven together into yarn.
Nano Tube : Look how strong I am

I bet it would break it it were under tension.
Chopping CNT without protective glasses?

But does it burn??
The glue laminating it does, the tube's never really burn. They melt at 4000 c
Wait you CAN see carbon nanotube? huh i didnt though its so large
You can not. This is many pit together with lamination

So much drama in those tiny swings. The other hand is balled into a fist and everything while the axe moves in slow motion 🤣

Wow
don't chop with the grain nooo
he didn't hit that with full power of muscle
That’s not the proper way to test materials. We use machines for these tests. You could apply very different forces on each object.
Great
Oh yeah and can we see this done with an axe it will deliver a lot more energy then a small hands hatchet
lol now try putting it on steel and hit it again
Would dull the axe before it even made the cut.
@@MrDrakePrice the point being the nanotube is stronger than the wood and thus is just being bent into the wood around the axe
