Calsdad, someone in that thread ( I don't remember who, I read both the first and second thread about this) mentioned km2 Kevlar. Some just used old vests or test panels to concoct this solution.

It's been a while since I looked at this - but there are different rating levels. The highest level can take a hit from 30.06 AP - and not get penetration. I don't remember if the standard says it should be able to take another hit or not.
These guys are all shooting at the plates with variants of .223 and .308. Before you start making a direct comparison between ceramic and steel plates I would like to see what happens to one of these AR-500 steel plates when somebody takes a few shots at it with 30.06 AP.
I'll have to read thru the whole thread and absorb what they did. The Kevlar/Herculiner layer sounds like it's the key to making the plate work so you don't get shredded with spall. The reason why they starting getting rounds thru the plate is that they likely work hardened and weakened the plate by hitting it in the same place over and over and over again. But 30 rounds is pretty impressive. If you're going to get hit 30 times in the same place you're just doing it wrong.
The Kevlar/Herculiner layer is basically a composite - like fiberglass is a composite. The real question probably is: what TYPE of Kevlar did they use - because I believe there are different types. This is the question to get asked - because Kevlar is available in sheet form. There are places you can buy it for building composite parts for race cars and so forth. The thing I don't know is if the Kevlar used for a vest is the same as the Kevlar used to make body part for a car. There is probably differences in the weave and so forth.
This has got me really thinking about getting some more armor (steel plates) - and doing the Kevlar / Herculiner thing.
I will likely set aside some funds to buy this rig if I don't win the contest because I have been wanting one for a long time, just couldn't seem to find a setup I could afford.
Same here. Maybe they'll give us like 10% off if we can get 10 people in on one bulk order.

You want Kevlar 29 for the layers. K29 is specifically designed for protection use in vests and armor.

Group buy for a whole roll?

That would be cool. We are in the same neck of the woods based on your location (I'm in Feeding Hills). If we could get a small group together in this area it would be awesome.
Thanks - if that is what they are using - it looks like you can buy it in sheet form from a number of different sources.
There are listings on Ebay:

Doesn't look like it's all that expensive - a yard is about $16.00

If a group buy gets going for Kevlar or plates (or both) - I would be interested. Maybe we could even do a "plate build" somewhere ?!
I would in for that. I could probably pull a few other people in also.
If I was going to go through the effort I would probably add some Kevlar to the Herculiner, but remember kevlar expires and becomes useless on a long enough timeline. The Herculiner and steel will never go bad so as far as storage goes, I'd rely more heavily on the Herculiner with less of an emphasis on the kevlar.

The AR-500 plates are NOT rated to defeat 30.06AP, only 7.62x51 NATO (.308). I would imagine 30.06AP would punch right through it like butter.
It will punch right through like butter.
I swear, you guys could fall into a bucket of tits and come out sucking your own thumbs.
30.06 AP will go clean thru a standard 1/4" steel armor plate or any other plate rated to only LIII. It takes a LIV or higher plate to stop a single 30cal AP round. Most tests I've seen it will only stop one at LIV, not multiple.
I only brought that up because the upside to steel armor is its long term effectiveness versus ceramics.
