Researchers at a Rice University lab are researching technology that that could potentially stop a 9-millimeter bullet and seal the entryway behind it - an advance that may have huge implications for ballistic protection for soldiers, as well as other uses. During tests, the researchers were able to shoot tiny glass beads at the material, which effectively stopped bullets in their paths. "This would be a great ballistic windshield material," scientist Ned Thomas said in a clip posted on the university's website. The group, which included scientist Thomas, Rice research scientist Jae-Hwang Lee and a team from MIT's Institute for Soldier Nanotechnologies, was looking for ways to make materials "more impervious to deformation or failure." The result would be better, stronger, lighter armor for soldiers and police, and protection for sensitive materials subject to small, fast moving objects, such as aircraft and satellites. The researchers were looking at a complex polyurethane material that they saw was able to stop a 9 mm slug and seal its entryway. When penetrated by a tiny projectile at a high velocity, the material melted into a liquid that stopped the fast-moving object and actually sealed the hole it made. "There's no macroscopic damage; the material hasn't failed; it hasn't cracked," Thomas said. During their research, they found an excellent model material called a polystyrene-polydimethylsiloxane diblock-copolymer. Using two different methods, the team was eventually able to cross-section the structure to determine the depth of the bullets, and according to their study, the layers showed the ability to deform without breaking. "[The layers] tell the story of the evolution of penetration of the projectile and help us understand what mechanisms, at the nanoscale, may be taking place in order for this to be such a great, high-performance, lightweight protection material." http://gma.yahoo.com/blogs/abc-blogs/sup...-news-tech.html

Yeah great stuff there, but how does it deal with the blunt force trauma generated by the bullets velocity.

Cool.
What if someone is shooting a .45?
What if someone is shooting a 9 at center mass, then works their way up to the head?

My first thought is it would deal with it much better than vests we have now due it being a gel like substance

If it has to seal a hole, I don't think it did a very good job at stopping the bullet.

Notice it says "seals an entry hole" but doesnt say anything about sealing an exit hole.

My guess is that it at least lets you live long enough to have to worry about it.

If it allows it to enter, where it then stops the projectile, how thick would it have to be to stop a 9mm bullet that is like 1/2 to 5/8 long?

Well, based on this... Quote:
Using two different methods, the team was eventually able to cross-section the structure to determine the depth of the bullets, and according to their study, the layers showed the ability to deform without breaking.
"[The layers] tell the story of the evolution of penetration of the projectile and help us understand what mechanisms, at the nanoscale, may be taking place in order for this to be such a great, high-performance, lightweight protection material."
It seems like the fact that it repairs itself behind the entry point is more important than the depth of the bullet at this point and they are still figuring out the depth.

I guess I'm just confused by this.

Which I took as the material will stop a 9mm slug, but no mention of the thickness needed to do so. In the case of windshields and armor it might not be a big issue, but for use as everyday body armor, it would need to be light and thin.
What confused me most is the "Able to stop a 9mm slug" then the next sentence they say "When penetrated by a tiny particle". What are they refering to as tiny?
Tell me you got a material no thicker than a cardboard box that weighs lees than 1lb per sqft that stopped a 9mm slug and I can make sense of that. Tell me you have a material 1 foot think that weight 30lbs square foot that stopped a "tiny" particle, and I'm not as impressed .

What am I missing here? I thought Kevlar has been doing this for years?

Kevlar does not re-seal itself after a penetration, it is also not transparent.
The article states they are looking at this material as a windshield replacement. At no point does it specifically state that it actually stopped a 9-mm slug, although there is some confusing wording. What they actually shot at it were "tiny glass beads", at a "high velocity". Nearly meaningless.
Other than that the material is apparently transparent, re-seals an entry, and stopped a projectile, there is very little hard information given.
"Potential" usually means that it Might in the future, but does Not at this time.

I'm thinking that they feel it will be able to stop a 9mm slug at some point (at a reasonable thickness). It seems to be still fairly early in development. I'm sure if they had every detail worked out, the article would be more in-depth.
And maybe the ultimate objective is not to make a PPE but rather use it for windows, windshields, etc...

This is the wording that confused me

I read that as they already know it will, and the wording of "was" indicates to me they have shown it. But it could just be poor journalism.

I read it as, "It has proven to be able to stop it but it is not yet in a form that is deployable." Maybe it's too thick or cumbersome or has some other qualities that make it not very useful just yet and those need to be worked out.

The first line said it had "potential" to stop a 9mm. If it had actually already done it, then they wouldn't have said "potential".
They "saw it was able to". That is different than actually seeing it happen. I took that to mean that it demonstrated a performance that could justify that assumption.
That, plus the reference to the glass particles.

I was wondering about that, especially if the exit is like, oh, hollow point sized and four times the "sealed" entry hole. Wondering what the learning curve is like for this . . . "Daggone it! Almost had it that time." Very cool to read, but Not Ready for Prime Time Players' Award for this one IMO.
