I was wondering if it would be possible/effective to make a latticework of CNTs in the lenses of some eye protection to increase their overall protective ability. It seems like they're thin enough where they wouldn't interfere with vision, but would they still retain their effectiveness?

Where does the line form to get this technology? I think the Chinese would be interested. So would the Iranians, North Koreans, Cubans, Venezuelans, ...

... but the material is so thin it will allow the projectile to push the fabric well into the body tissue. You're assuming the armor consists of one layer of fabric. Once you have bullet-proof fabric the weight of t-shirt material, all sorts of body armor lighter, and more comfortable, than what is now available become feasible: a layer of the (still hypothetical) CNT fabric, a layer of something to absorb and distribute energy (anything from cotton batting to fine-mesh titanium chainmail to the other hypothetical body-armor component: fabric impregnated with a non-newtonian fluid) and another layer of the CNT fabric would do nicely.
Of course, the less protective, but far less obtrusive, one-layer of fabric version might become normative for folks who have reason to fear assassination.

Bulletproof at what thickness? I mean, would the thickness and drape and feel of the fabric be the same? I'm somehow reminded of Monty Python "fake news" reporting about a man who crossed the Atlantic in a life raft...a specially modified life raft with a 38 foot fiberglass hull, three luxury cabins, twin diesel engines, a hot tub, etc....
At some point, what they call a t-shirt just isn't a mere t-shirt anymore.

There would be perforation with this nanotube armor, but a great deal less trauma than a through and through wound channel.The "silk" analogy makes much more sense, though I'd suggest that it would more accurately "bullet resistant."

So why not just make bullets out of carbon nanotubes?

I see a great marketing oppurtunity here for bullet-proof pajamas. Just the thing for the WOD, no-knock raids that seem to be so popular.

the bullet would push the fabric into the body causing all kinds of damage, but the fabric won't break?hmmm..Seems so, Massive internal injuries (broken bones/ruptured organs....dead person)
...bright side..no holes / tears in the Tee-shirt.

Bulletproof underwear, that's the future.
Having heard the DSO decoration/medal described as the award
for "D-ck Shot Off"...
bulletproof underwear sounds like a winner.
As long as males of the species go to war!

While it may be possible to eventually construct fabric from threads so strong that they will not be broken by the impact from a bullet, there still remains the problem of how to dissipate the bullet's energy.
As illustrated in the article, if the fabric stopped the bullet, what would happen if this was a 'bulletproof' tee shirt, is that the bullet would proceed onward through the skin of the target subject, dragging the tee shirt with it into the wound.
For any fabric to prevent wounding by a bullet, it must have an energy-absorbing backing, which means a support or padding that can dissipate the bullet's kinetic energy over a large enough area of the human body so it will not suffer more than a bruise.
To: Dr.Zoidberg
Not to mention the absence of shock wave damage.
There would be perforation with this nanotube armor, but a great deal less trauma than a through and through wound channel.

>> Could be wrong, but I'm assuming the nanotubes spread out the energy of the impact over the whole shirt.
Preferably to the back of the shirt which would propel the victim towards the shooter...
To: theBuckwheat
Friction alone would significantly impede dragging of the nanotube undershirt into the wound, i.e., a significant amount of the round's energy would be transferred to the skin surface surrounding the impact.

Other materials such as fluids with extremely high shear forces would probably be added so that the result would be like wearing a thin, flexible suit of armor that would harden in an instant and dissipate the mechanical force of impact into chemical and thermal energy. The concept is contrary to common sense and it took me several readings and some thought before I understood it.
To: LibWhacker
Sounds cool, but I don't want to be the first to test it.
