What to do with Kevlar.?..Pics

..I happened onto a 28x26x3x8" sheet of kevlar. It's a few years old and has seen some weather, but looks solid. I guess a perforation test is in order. This type is used to line the walls at military guardposts and such. (That's not the tin shack you think it is))
..Any ideas? Maybe just start at .22 RF and work up.

And fiery auto crashes
Some will die in hot pursuit
While sifting through my ashes
Some will fall in love with life
And drink it from a fountain
That is pouring like an avalanche
Coming down the mountain
Your sheet is four dimensional?
28 inches by 26 inches by three eighths of an inch thick. Sorry if I confused you....[:o)]

I knew what you meant Tap![:D]
Try an arrow topped with a field tip on it.[;)]
..Bullet resistant does not mean arrow, knife or ice-pick
resistant. They spread the fibers, allowing penetration.

Bingo.[:)]
I wonder if an AP bullet would react in a similar fashion, spreading the fibers apart?

..I suspect that Mr. Perfect did also. Just giving me a hard time. No problem....[:D]
30 cal AP will go through it. They loaded billions of rounds of it in WWII to go through the coconut logs in the Pacific Islands.
I had a feeling it would go right through.
..I think that most 7.62 will breach it. I'm betting that .223 FMJ may defeat it.
..I have some old black-tip in '06 or .308. I think that's AP. I'll work my way through the handgun rounds first, then .223 and then 7.62.

I tried a .30-06 on Kevlar a few years ago, handloaded with 150gr Barnes X's, and it was one of the heavier loads in the book. Stopped it cold. Really surprised me. I think the FMJ's will do the same thing.
It's still fun, but not scientifically accurate. A bullet that might have been stopped by a perfect condition panel could penetrate one that has been damaged by a previous bullet, then you'd think the panel wasn't able to stop that round when it is.
..I happened onto a 28x26x3x8" sheet of kevlar.Could be a helicopter panel they also use for small structures.
5.7 x 28?
I was thinking the same thing.

lol
Kevlar and other aramid fibers degrade when exposed to ultraviolet (UV) light.

If it's the green tipped SS109 (steel core)bullets, you are probably correct. [;)]
....try a 12ga slug for me.
Can we wait till the last shot for that one [;)]
3/8in. of Kevlar alone should stop most all handgun/shotgun rounds and smaller shrapnel, but just about any centerfire rifle round would penetrate.
When you're talking about any sort of rigid ballistic panel it's rating would depend a lot on what the internal hard panel is made of.
How much does this panel weigh?

..I'd guess about 30 pounds or a bit more. The panel is big enough that I can shoot different areas of it without clustering the shots. I just don't have time today to continue, but I'll post some pics when time allows.
..I'd guess about 30 pounds or a bit more.Wow! A panel of that size made from just Kevlar would weigh only a fraction of that.
With this much weight that material is just a covering for something pretty darn substantial - and much more significant when it comes to ballistic properties.
What you have is very possibly a ceramic plate with the Kevlar intended only to stop smaller shrapnel and cut down on ricochets/fragmentation.

..The company it came from does a lot of layered ballistic work. These panels may be on the inside or outside of armor steel. They also use layered poly-glass for windows. This piece is not direct from the manufacturer. It is some heavy stuff and if you handle the edges, it feels like a hundred tiny splinters in your hand.

..Yep, the .223 went through but left no mark on the tree behind it. For some reason, I can't talk my wife into holding it up while I shoot some .22's at it...[:o)]
Geez,.....why not ask her to put an apple on her head at the same time![:0][:D]
