Will new modern body armor stop swords and arrows?

LOL! Magic missile!

Anyway . . . don't you know you can't effect mass murder with a throwing star?!? ;)

Thank you for spelling that right!

BTW, now that I think about it, a military friend of mine told me you could knife someone through a kevlar vest. I don't know what you consider "modern body armor" but that at least would not stop the stuff you're describing.

like kevlar? naw. kevlar works because bullets spin [i think it was] but im pretty sure that body armor worn when there is the danger of arrows and swords.... protects against it. :p

Not if they are teflon coated. Nasty nasty then.

A trauma plate (a ceramic plate you put into a pocket in your vest) probably can protect against arrows and bolts. Regular kevlar won't.

They have a special body armor made for sharp objects, for prisons and the like, so that there is protection against shanks and knives and such. However, those won't protect you from bullets, just like how bulletproof vests dont protect against shanks.

Isn't it because the weave of the Kevlar distributes the force over a wider area?

and also you wont be able to move ;)

yeah i think kevlar absorbs the force of the spin or something like that and spreads it out, so it slows down. i imagine teflon would not help that very much...

i bet the heavy hard ceramic stuff would, but kevlar might. i dont see the force behind arrows or crossbows as more powerful then many bullets. kevlar keeps it from penetrating but it would wound you. swords...doesn't matter if it goes through or not, its a crushing impact.

A bulletproof vest will not stop a knife st@b (Darwin award resulted from this, I think) and probably not a solidly fired crossbow bolt. It will stop a knife slash, but a sword blow would probably inflict enough kinetic damage to kill or seriously injure you.

Ceramic plating on the other hand, will stop a st@b or bolt. A sword would still deliver a major blow.

kevlar would probably be able to stop a crossbow bolt. the reason it cant stop a knife is because after the first impact of the st@b, there is a second shock that the knife applies which goes through the kevlar.

I can say honestly that I've never tried and do not wish to try either of those situations. :p

As has been mentioned, modern body armor like what the military uses will not stop edged weapons though I wonder about the trauma plates. The new ceramic ones might not, but the older steel ones might do enough in combination with the underlying ballistic cloth to at least diminish an attack.

Arrows/bolts would probably not work against ballistic cloth for the same reason that bullets don't -- narrow point of impact. The ballistic cloth operates by distributing the impact along its fibers, which are intertwined like crazy (yes, this is the technical discussion).

BTW, I think the newer sets of body armor no longer use Kevlar and are using more advanced stuff that's lighter and more effective. My personal set is an older version, but I've seen the local Security Forces (and members of richer units on base) wearing the newest style, called "Ranger" body armor. Mine cannot accept a trauma plate, but I'm not sure about the other ones I've seen. There's bound to be additional types out there as I imagine that SOF types use something entirely more fancy and more expensive.

Sure it is...compare the weight of an arrow to the weight of a bullet. Crossbows can shoot at above 300 feet per second. Throw a broadhead on the bolt and I think it might rip its way through modern armor.

no. Kevlar will not stop sharp objects or edged weapons. bullets are not sharp

Sharp swords are mostly a modern hollywood thing. Some swords were designed more along the lines for stabbing but alot were simply for crushing bones. A blunt weapon had to be much larger than a wedge-shaped weapon to illicit bone-crushing hits. You have to figure metals were brittle by today's standards and just think how quick even those serated blades dull out if you use them for cutting any piece of meat with bones in it.

The ceramic plates will stop a knife or edged weapon. the plates are about 9 inches wide by 15 inches long about 1 inch thick and weigh 15 pounds each. on the new kevlar there is a pocket in the front and back that you can remove the plates when necessary. The problem is that when worn, they add 30 pounds to your body and seriously decrease you mobility

a longbow bolt will go through sheet metal, doors, thin walls and pretty much anything.

i don't think that modern BPV's will protect against it.

Like kami said, the arrows and bolt typically have more force. They also have considerably less range and accuracy, mated to more weight and size per munition, else they'd still be used for modern uses like throwing grenades and the like. Alot of times an arrow will go clean through a deer whereas the bullet will hardly penetrate, even though they both are about the same diameter.

Like someone else said, bullets are not pointed for a reason. The bullet will do traumatic bludgeon damage because all of its kinetic force ends up in the animal when the bullet splays. An arrow that goes clean through doesn't leave much kinetic energy in the target.
