China, please respect this secret. Its made up with grapheme threads. Its impossible to understand exactly so we made a little picture with the molecules and such so you can’t copy it.
I don’t know if this will actually pan out the way that they imply in the title; armor needs to have a lot of different characteristics in order to be practical. As in, resistance to heat and cold, resistance to acids, alkalines, petroleum distillates, salts, UV, and oxygen, and also resist deformation. Multiple materials have displays significant promise for armor, but had a very short lifespan in real-word conditions. For instance, there was a material trademarked as Zylon that was supposed to be better than Kevlar, and it was used extensively by Second Chance (a body armor company); several cops were killed when their armor failed, and the armor failed because of exposure to sweat and ambient heat.
Yeah, this is a super cool development, but remember that everything that comes out at this stage is hype.
The armor works perfectly fine as long as it’s not exposed to oxygen. But when’s that ever going to happen?
That by itself isn’t terrible, that could still be used if it is sealed in something like an era brick if it’s good enough.
Yes… that’s why they use the word “could”. This is how research works and what reasonable science reporting looks like. There were no promises or wild claims made in the article.
Layer it with Kevlar and good?
It really depends on whether it can be made to meet all the other criteria required for armor. I think that it’s too early to make any good predictions.
I can’t wait to find out how toxic this is.
Good news, it’s completely non toxic.
Bad news, it costs 2 million dollars per square foot.
The pentagon will now take your whole paycheck.
Thank you for your support, patriot.
The article says the process is scalable.
Good news, it costs 2 million dollars per square foot, so they won’t militarise the police further with it.
Well not immediately… Years from now when the military develops something even better then this will all become surplus and sold off to SWAT teams etc. for next to nothing.
They will make it into a mandatory dress uniform for school children.
With these bonds so dense, I want to imagine that it would actually be quite non-toxic as these is little to react with.
Then again, I’m not a bio chemist
…and uses it to oppress and/or disenfranchise poor people
America bad
Indeed
You mispronounced promote American interests.
Why don’t they just use diamond, the hardest metal?
Hardness isn’t the best thing to have in armor. In fact, extreme hardness means extreme brittleness.
Tensile strength is more desirable in armor. That’s the sort of strength that a string or rope, or Kevlar will have.
Those can stretch a bit before breaking.
Kevlar will stretch a bit when catching a bullet, this does a few things, but importantly it slows the bullet before stopping it.
So this new material will likely show extreme tensile strength rather than hardness.
Correct. 🙂 Reminds me of when I wanted new tires & I was complaining about how some tires were rated for a criminally short life. I wondered which ones lasted the longest.
The mechanic then remarked that sure, they can make tires that last a hell of a long time & never puncture. But the ride would be so terrible because the tires would be tough, stiff, would work your suspension harder, and it would cost a fortune to boot. It’s not worth it. There are multiple material, usage considerations when making a product. Really makes you appreciate the experts in their various fields.
Not to mention, really hard tires would have very poor grip. The rubber needs to be a bit softer to squish around all of the little imperfections in the road, technically increasing the contact area and providing a little lateral bracing (probably not the right term so I hope I’m making sense). This is why a lot of performance tires have shorter lifespans then other tire types, because in addition to a different tread pattern, they also often use a softer, “stickier” rubber, which wears out faster.
I thought Dragonforce was the hardest metal known to man?
Lol, this
So this is what John Wick had in his suit
I loved those movies but they went way to hard into that suit in the later movies. I got ridiculous lol.
My favorite part was when he held the jacket up like a curtain. The material may be bullet proof, but the bullet will still push it out of the way like that lol.
They did Rambo the franchise a bit.
Same with the Fast&Furious it used to be about import vs muscle and real street racing. Then it became jumping hyper cars from falling buildings to the next building over and turned to shit. Like most over milked series.
Waiiiit, was it actually meant to be about import vs muscle, like that was it’s intention? Or did they just happen to do that.
I’ll be eager to know what the results will be about it’s resistance to bullets and sharpened objects.
Currently, garbage. They used it to reinforce a polymer to go from a strength of 50 MPa to 70 MPa. Kevlar is 10x stronger, commercially scaled, and cheap
Of course it’s plastic.
I’m sure it will mix well with the depleted uranium smoke the targeted crew will already be breathing.
Microplastic, even
I mean, we have tried to completely stop, or at least slow, the refinement of crude oil, because there’s so much fucking byproduct that is made from it and is subsequently recycled and converted into plastic. What else can we do with all that fucked up petroleum byproduct besides make it all into some form of usable plastic?
it’s very lightweight though, so it could reduce plastic usage by mass, by reinforcing plastic/other materials.
There’s also no reason why polymers need to be made out of oil: See PLA, cellophane, viscose, etc.
Whether or not it’s plastic isn’t as big an issue as whether or not it’s biodegradable within a realistic timeframe.
everything is degradable with enough heat
I skimmed the article, scrolled down but people hasn’t mentioned its mechanically Chain mail in atomic scale yet? Did I read it wrong?
It is
hello I would like to order a thousand full plate mails

I’m sure this is real, but I see a headline like that and I think of schoolyard talk. Like, nuh uh, my armour has 100 trillion bonds, you can’t shoot me.
They must have hired some former Nvidia marketing guys.
This is still basic research, it’s not close to commercialization.
molecular chainmail
Goes on to form company called General Products, builds spacecraft hulls. 😉
Please, could we move to Known Space?
