How Strong is bulk Kevlar? How Powerful is the 9mm Luger?

[scourge18a]

Do you know the approximate size of kevlar in the 6 lb ammo box? Is it 1 piece?
Or conversely, approximately how much does a 55x17" ish chunk weigh?

 

[Frontier Firearms]

The 6LBS can could be any size or number of pieces. The individual pieces are around 8 LBS.

If you are looking to make a target stop, its best to order by the pieces specified under the link.

If you bond the layers it works better. Wired up a machine for that once

The Irish level 4 vests that you have listed, I assume there must be some sort of hard plate in there? What material is that plate made of? Thanks eh

 

[Dodo Dug]

Very interesting test!

Subbing!!

Half of the vests have no size or what is not rated? Condition ? Level of protection?

 

[Rifleman1984]

Do you have any still for sale?

I have a bunch of yellow, none of the white.

Interesting fact, a 7.62x39 steel core will stop at around 150 layers of the yellow Kevlar.

5.56 blasts through.

Was the 5.56 round a Green tip?

Was the 5.56 round a Green tip?
I doubt it would matter. Its the velocity that makes it zip through. You need something that breaks up the bullet in order to catch it.

The vest on the site are all of the Irish level 4 vests. We do not post condition, we use pictures to display this.

Were those round nose FMJ or round nose copper plated bullets?

How can you cut this stuff? Will very sturdy scissors or a box knife cut it?

Correct that pretty much any 5.56 would penetrate that vest like paper. Not so much about needing to break a bullet in order to catch it. Throw the round slow enough and the kevlar will 'catch' it without deforming the round at all.

IT's not all about the velocity. I bet a 5.56 travelling under 800 FPS would still penetrate that vest as long as it was stable and not tumbling.

There are a lot of variables that affect whether something will or won't penetrate. Elasticity of the projectile being an important one. Relative hardness of the projectile in relation to the target being another.

I did a test of 5.56 AP rds on 3/4" ballistic Fibreglass (think kevlar, but laminated into a solid board) and it was still doing complete penetrations at under 500FPS.
