Kevlar 29

Would using kevlar 29 (balistic kevlar) work for creating bullet resistant door panels or sub enclosures. Don't even bother asking why I am just wondering if it would work. What i have read says that kevlar 29 is used in vests with lots of layers loose, but would it work stiffened in resin? how many layers would be needed to stop certain size bullets. Or if anyone knows the force of impact it can recieve, I am in physics and i think i could figure it out from that type of data.

Thanks

Yeah most of the military still uses flak vests that have no ballistic protection, but now most of our expensive units (Recon, SEALs, Delta) are wearing lightweight vests that will stop a 5.56 round from as close as 25 meters.  Course those are only for our spec warriors that are well trained (read: lots of money spent on them) because those nice vests with all the accessories costs a buttload

Kevlar is a "reactive Fiber" it has to be loose inorder to work efectivly. If you resin it, it will still work, only, a whole lot less effectivly.

As for the flack jackts we wear in the Corps....

The new vests, with the balistic steal plate will stop s 7.62 round from a distance. Point blank...... i wouldnt want to try it. The vest with out the steel plate, will still provide protection from Flack, and is rated to stop handgun rounds point blank.

Kevlar is an awesome invention.  They use needles and thread to sew the layers of fabric together, but bullets and shrapnel have a bitch of a time getting through, especially if there is a layer of material between the projectile and the kevlar to slow the velocity of the projectile down (like an armor insert, or a car door panel).
