Anyone know the cost per kilogram?

Edit: Apparently $20,000/kg

[–] AeonFelis@lemmy.world 2 points 1 hour ago (2 children)

Why don't they just use diamond, the hardest metal?

[–] chaogomu@lemmy.world 1 points 39 minutes ago

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.

I did your mom stronger

At least it’s not 100 trillion James Bonds.

[–] cupcakezealot@lemmy.blahaj.zone 1 points 5 minutes ago

Not if Hank Scorpio has anything to say about it.

[–] FauxPseudo@lemmy.world 19 points 6 hours ago (3 children)

I can't wait to find out how toxic this is.

[–] brlemworld@lemmy.world 4 points 2 hours ago

They will make it into a mandatory dress uniform for school children.

[–] phoenixz@lemmy.ca 4 points 2 hours ago

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

[–] Zron@lemmy.world 8 points 3 hours ago (2 children)

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.

[–] HEXN3T@lemmy.blahaj.zone 2 points 2 hours ago (1 children)

Good news, it costs 2 million dollars per square foot, so they won't militarise the police further with it.

[–] IphtashuFitz@lemmy.world 3 points 2 hours ago

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.

[–] Batman@lemmy.world 1 points 2 hours ago

The article says the process is scalable.

[–] Snapz@lemmy.world 26 points 8 hours ago (2 children)

....and uses it to oppress and/or disenfranchise poor people

[–] BeMoreCareful@lemmy.world 9 points 6 hours ago

You mispronounced promote American interests.

This is still basic research, it's not close to commercialization.

[–] HelixDab2@lemm.ee 47 points 13 hours ago (3 children)

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.

[–] echodot@feddit.uk 15 points 7 hours ago (1 children)

The armor works perfectly fine as long as it's not exposed to oxygen. But when's that ever going to happen?

[–] MDCCCLV@lemmy.ca 2 points 2 hours ago

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.

[–] Soleos@lemmy.world 5 points 8 hours ago* (last edited 8 hours ago)

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.

[–] MonkderVierte@lemmy.ml 7 points 11 hours ago (1 children)

Layer it with Kevlar and good?

[–] HelixDab2@lemm.ee 5 points 9 hours ago

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.

So this is what John Wick had in his suit

[–] NotMyOldRedditName@lemmy.world 12 points 6 hours ago (2 children)

I loved those movies but they went way to hard into that suit in the later movies. I got ridiculous lol.

[–] nul9o9@lemmy.world 6 points 4 hours ago

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.

[–] BeMoreCareful@lemmy.world 4 points 6 hours ago

They did Rambo the franchise a bit.
