Scientists Turn T-Shirts Into Body Armor

separsons writes "Scientists at the University of South Carolina recently transformed ordinary T-shirts into bulletproof armor. By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."

There are only a small number of ways to effectively and pragmatically stop a bullet. One is to deflect it like an armored vehicle. The second is to completely absorb the energy by means of a sacrificial material, such as ceramics. These materials are typically only good for stopping a bullet or two. The third is to prevent penetration and to slow the round as quickly as possible using a super strong albeit slightly elastic material. The third route typically means organ and bone displacement, despite lack of penetration, while its energy is absorbed by the vest.

      So your options are; deflect, absorb, or slow over time - or some combination. Most soft body armors use the last option which is why black and blue bruises are typically considered a blessing. Armor such Dragon Skin uses a combination of the first two - which is why its so much more effective at preventing all forms of bodily injury.

    I think there's a good deal of misunderstaning about bullet resistant soft body armour on here. I've seen two posts so far that say that the shape of the bullet has something to do with defeating a vest, as well as a bullet being "tangled up" by the material. Neither is true.

    Bullet resistant soft armour works because of the strength of the individual fibre and how its woven. It also has to do with the friction coefficicent of each fiber. Generally, it's woven in a waffle or checkerboard pattern for each layer. There are lots of layers, too...20 or 30 is common. When a projectile strikes the fabric, the crossed fibers lock against each other (this is where the friction coefficient comes in. Two Kevlar fibers crossed at 90 degrees will not want to move). So, in theory, one layer could stop a low-energy bullet. However, it would still be fatal to the person wearing it because of the amount of energy transferred to them. So, by using multiple layers, that .38 or 9mm round's energy is spread out over perhaps 5 or 6 inches. It's still going to hurt like hell, but you'll live to tell the tale. Current NIJ spec for the backface deformation of a vest is something like 12" of clay, which translates to something like 4 or 5 inches of compression in a human. It's like getting hit with a baseball bat swung by a AAA player.

    So why does bullet shape have little to do with it? Even a pointed bullet deforms on impact; the sharp point isn't going to get through more than a layer or two before it deforms flat. The threat rifle rounds offer is that there is just vastly more energy then a pistol round. All of these materials have a failing point, and even if the bullet was stopped, the amount of energy transferred to the wearer might be lethal anyway. That's why rifle-rated vests (something to stop a .223 or a 30-06) have trauma plates, which is a 1/4 inch (or thicker) ceramic plate. It's heavy, uncomfortable and unbendable, but it'll stop just about any reasonable threat.

    Sure, we could come up with a list of unreasonable threats, but in reality most shootings are with lower energy handgun calibers (9mm/38spl/25acp/32acp), which a standard IIA vest will stop without breaking a sweat.
