Diamonds are rarer than gold dipshit.

Because it's transparent making it useless against lasers.

Because Mithril vests exists and they've already proven the capacity to protect Frodo from the strike of a mountain troll.

They use ceramic plates since it's also very hard, and easier/cheaper to manufacture, and is easier to shape into unique shapes, like hexagons, which can be layers in tiles that direct energy from an impact into a larger area
They also use composites, metals, and other compounds, almost all of which are better than diamonds lmao

It's not a metal and it's not hard either, retard. You can break diamonds easily with a hammer.
They just cut everything else, that's why they're used.

>>11189792
You can make diamonds in a lab

>>11189792
>carbon is rare

>>11189791
It would be too heavy. 1 kg of diamonds weighs something like 3 kg

>>11189873
it's also extremely bulky. 1 cubic feet of diamonds takes up like 15 cubic feet.
crazy.

>>11189873
No, 1kg of diamonds weighs 1kg, retard.

>>11189839
>it's not hard either
>Mohs scale of 10

>>11189791
It's not ductile.
You need to be able to move.

>>11189930
So as I said, it's a 10 on a scale based on how well it cuts other things.
Diamonds are still brittle and not actually tough.

>>11189936
Toughness and hardness are not the same thing.
Diamonds are hard, but they are not tough.
Toughness is a measure of a materials ability to plastically deform without fracturing.

>>11189945
My mistake then. I did mean toughness, I just used the wrong term for it.

>>11189873
Hello, American

Dragonforce is the hardest metal.

The oil industry won't allow it. Imagine if cars were made out of diamond, the hardest metal. No one would ever die or buy new cars.

>>11190259
They would break more easily than regular cars.

A car made out of diamonds would be too heavy to drive. Also unlike other metals diamond can't be cast in a mold, so how would you even get it into car shape

>b-but this shitty site I cherrypicked says it is a metal!
It's an allotrope of carbon, it's not a metal.

Because diamonds are hard but not tough. You can smash a diamond with a hammer easily. Diamond armour would just shatter if shot.

fuck the mods lol.

>>11189791
Could you make a tank from solid diamond? It would be undestructable

>>11189791
better yet, make them of airplane black boxes

>>11189791
Diamonds aren't a metal.
Bulletproof vests are designed to stop bullets, bulletproof vests are specifically designed against the way a bullet operates, a bullet will go through a diamond before the equivalent in bulletproof vest.

>implying you couldn't paint/cover the diamonds with a non-transparent substance

>>11189791
Mithril was canonically thought to be made of crystals...
Could we defense mod P.A.Ds to be bulletproof?
Could we inverse wave piezo-electric crystals to absorb shock?
I ask in jest. I have already figured out how. KEKEKEKEKEKEKEKEKEKEKEKEKEK

I laughed.

Diamonds are transparent and, due to their natural pyramid-ish shape, there are only two ways you can make diamond armor (remember, it's too hard to make into different shapes)
You either have the blunt part forward in which case if you get hit you might get cut by the sharp edge, or the sharp edge points forward which shatters the crystal.
So basically the best form of diamond defense is to have the blunt part forward with some extra defense on you as to not get impaled, BUT, since it's a perfect crystal structure it will actually amplify laser gun attacks so you die

>>11190546
way to miss his point lol

"metal" has different definitions, in astronomy everything past helium is a metal

>>11190929
You could just stack them with a second layer of diamonds so theres blunt parts on both sides. than you put a layer of mirrors behind them to defend against laser attacks

>>11190929
>natural pyramid-ish shape

>>11189791
because diamonds are made out of micro jews, and if you got shot it'd be anudda shoah

>>11190530
Oh sorry, I forgot internet is SRS BSNS for a sec, thanks for reminding me!

diamonds are brittle. it's hard to scratch a diamond but it is easy to smash them.

>>11191809
that's only really a good answer if you don't know that some very brittle materials are already used in armor

>>11189791
>carbon
>a metal

>>11190202
Woke

>>11191818
I don't think that's true because brittle materials do not make good armor. Usually armor is made out of non-brittle plastics or non-brittle metals. Perhaps you are referring to some non-brittle materials which are designed to absorb kinetic energy through catastrophic structural failure? IMO, more brittle than steel means something much different than "brittle." Do you mean that some armor is made out out of ultra-tough materials which are not brittle at all but are still more brittle than steel?

>>11192191
i don't know if it's technically true or not because you have to mix terminology from severely different fields to make it fit, but i choose to think of it as if it is because it's funnier that way

Holy fuck, so many newfags/r*dditors in this thread. I'm losing hope.

>laser zaps 1 mm thick substance and proceeds to explode 1 litre worth of squishy squishy water bags hidden behind it.
>b-buh trust us goy our 99% reflective substance really is just as effective as the primordial Ylem!

You know out there somewhere some skunkworks engineer finally got pissed off and just out and killed all the mysteriously-similarly-surname'd salespeople who came to his lab after they left.

>>11189791
What are you protecting that's more valuable than that many diamonds?

>>11189839
>it's not hard either, retard. You can break diamonds easily with a hammer
You have a bad understanding of what hardness is. Almost as bad as OP.
Glass is also very hard. That's why it's cut with diamonds.

>>11189792
You must be at least 18 to post here.

>>11189791
Diamond is brittle and not good at absorbing impacts without shattering.

Would a vest made out of densely woven carbon nanotubes be better at absorbing kinetic energy than a Kevlar vest?

>>11192209
Smartphones fucking destroyed the internet in general.

Because bullets travel over 400 irons per car and the resulting explosion of the impact would kill the wearer from an immovable object impacting such an unstoppable force causing a micro black hole which emits radiation that turns everyone gay and gives them cancer.

The only one who got the meme behind OP

>>11189792
go back to minecraft son

>>11192464
I already admitted that I got the term wrong and meant toughness, buddy.

because diamonds are not malleable or ductile which makes them brittle albeit under very high pressure.

is 1kg of feathers heavier than 1kg of steel?

>>11192155
To be clear, you're talking about ultra-tough composites which are not even even remotely brittle and yet are more brittle than steel?

>>11194668
no i am talking about the sort of composites where sheets of a hard material is layered between binding layers that keep them together

>>11194753
So is that not ultra-tough or is it not not even remotely brittle? Where am I going wrong in my thinking?

I'd imagine you would have a really hard time moving around with diamond on you

I will make a bullet out of diamond cutting material

>>11189791
so many newfags
dont know the op

>>11194797
in that case half of the components are brittle, they are just held together by the other half

when such a composite performs its function, the brittle component tends to shatter

>>11189792
What a kosher statement fren.

>>11189792
That's right goyim that's why it's so expensive
