IAMOND-HARD ARMOR The media tends to depict bullet-proof armor as something that’s thick and heavier than regular clothes. Despite being for bodily protection, the added bulk of that armor might restrict a person’s movements. But scientists at the City University of New York’s Advanced Science Research Center (ASRC) have found that diamond-hard armor doesn’t need to be thick. The key to less-bulky protection is graphene, a tightly-packed layer of bonded carbon atoms one million times thinner than a piece of paper.
The researchers discovered that two layers of graphene stacked on top of one another can temporarily become as hard as diamond — and just as impenetrable — when struck by, say, a bullet. The hardening of the new material, called diamene, only happens when exactly two sheets of graphene are layered together, according to the study published in Nature Nanotechnology. When more sheets were added, the hardening effect didn’t happen.

“Blofeld would order a few.”
Ok...you’ve driven me to watch “Spectre” tonight...actually watching it right now.
Given enough kinetic energy, bullet proof armor that merely stops a projectile would not be sufficient.
Laz, I hope that you do make a graphene ping list. I would, but I am quite computer illiterate and instructions seem to be hard to come by.
Graphene, I understand, can be clear. I wonder if this item would be clear thus making it good armor even over the head and eyes? It certainly would be very light weight.
Got it. Two sheets only if you want it to get hard.
Thanks!
Unobtainium takes over the world. Silver makes a little move, so cue the graphene blurb.
I am not sure how much it costs to manufacture artificial graphene, or if it's even real, but it's interesting.
I doubt that, anybody who is worth spit with a firearm will just go for the head shot.
Just takes practice.
Perfect example!
Only improvement would be adding the word tactical....”Tactical LinearFlux Graphene keeps you HyperCharged!”
;>)
Which actually might apply as they can retain a charge in really cold weather when other battery tech. punks out.
I bet thin body armor leaves one hell of a bruise.
Transparent aluminum has a potential competitor.
That version of graphene has not yet been discovered. This is a flexible version that hardens on sudden pressure.
If they do create an always-rigid version, however, there will be Secret Knives everywhere.
“Given enough kinetic energy, bullet proof armor that merely stops a projectile would not be sufficient.”
I know an ATM tech that was shot twice point blank close to the sternum while wearing a vest. It knocked the wind out of him. To add insult to injury the FBI questioned him. The robber used .38 lead round nose ammo and the FBI suspected it was an inside job because it was obvious the week loads wouldn’t penetrate.
If the material is diamond hard, won’t the force automatically be spread across the material?
In order for force to transfer there needs to be some deformation of the suit. Right?
“If the material is diamond hard, won’t the force automatically be spread across the material?”
No, hardness is a measure of how resistant the material is to being scratched or indented. Toughness is a measure of how well a material absorbs a shock or impact. Materials with a high hardness can tend to be brittle and not very good at absorbing an impact.
Graphene (in a single sheet at least) seems to be very hard, but brittle. I am guessing that adding the second layer solves the problem of it being brittle, but that doesn’t mean it necessary would be better at absorbing the shock.
