Stopping green tip is nothing to scoff at, there are even some hard body armors that can't! You sounded sarcastic about the "wicked" 5.56 but that chunky boy was thoroughly bullet proof.
Those are pretty poor level 4 plates then, or it's level 3 or 3+ which isn't designed to stop rifle rounds. Level 4 hard armor has to stop a single 7.62 nato black tip (or 30-06 AP round) which has WAY more speed and energy than M855A1 EPR (green tip 556). I'm not sure what hard armor you're referring to that can't stop green tip, even AR500 can.
Soon as you mentioned the resin being soft I had an odd thought. Can you make bullet proof candy? Layers of brittle with taffy or melted licorice between? ... Its a strange morning..
Epoxy is a suboptimal resin for binding glass for this purpose. "Resin" comes in a thousand different varieties and PVB is more like hotglue rather than 2-component epoxy.
PVB is similar to double sided clear tape. Unlike the resin you used it remains flexible more like rubber than plastic. When using it to laminate glass you place down a sheet of glass then apply the pvb sheet to the glass then lay on the next sheet of glass and apply heat and pressure to remove air bubbles. It does not take much heat or pressure to do it. A hot plate turned on after the glass pvb sandwich i laid on it with say some ply wood and a cinder block laid on the plywood is enough pressure and let the hot plate heat up to a couple 100 deg f will be more than enough then you turn off the hot plate and let it all cool down. To rig it up for shooting it for testing you would want to make a wooden frame around it and a dense rubber material say archery target matts or rubber mudflap material between wood and glass around the edge of the BP glass panel. You can screw the wood together
Yeah what I was noticing. The materials are good, but there's no outer frame to really secure them (it being a small surface area doesn't help on shock absorption either, but can't expect him making a huge panel)
You're supposed to shoot the glass side that way the pieces don't get blown apart because the polycarbonate is what keeps the glass together and not shattering into your face after it's been shot as you saw in your second shot of the bulletproof glass you made
FYI some ballistics information here, the green tip 5.56mm used (also not .556, that would be over a half inch in diameter, its actually .22cal just going very fast) is green due to the designation M855, which includes a small steel penetrating tip that did much better than a full soft projectile.
You want to shoot the glass side for a couple of reasons. 1) the poly is a polymer so it'll do a good job holding glass in place after impact. 2) the poly is impact resistant and considerably more flexible, so it will bend and absorb the energy thanks to it's low yield strength compared to glass which has a high yield strength and is very brittle. This also prevents glass from being thown at the person it's protecting. 3) the idea of the annealment and why the glass works is because the name of the game with bulletproofing is removing energy from the system. The small suspersonic piece of metal has a high amount of energy, so you want something that can take that energy and disperse away from you. Bullet proof vests work by taking the energy and dispersing it across a larger area of your body. That's why it's painful and kicks like a mule, but it keeps you from turning into swiss cheese and makes the impact....less lethal, let's say. Now contrast that with bulletproof glass, ususally this is on a car or on a room door. In a car, you can flee and leave the danger, so all you care about is removing the energy. When the glass breaks, the large shards have more mass than the bullet, and as they break they take energy with them, sometimes falling off the car and removing energy from the whole system entirely. Their lifespan is limited or course, but that's where the PVB and large shards also come in as they can allow multiple shots being taken before failure which aids in fleeing. A room on the other hand is usually designed for continued resilience, so they probably have another layer of poly on top to squeeze everything together, and may even have multiple layers of poly inside with more glass sandwhiches allowing even more resilience. And like a bunch of people have said, usually these are tested while mounted in some way because it prevents it from moving and allows the glass to do it's thing instead of turning and allowing the bullet to chew it up from a glancing blow. THIS IS NOT A CRITQUE THOUGH! Just a little info as to some of the things you were unsure of or curious about. I know I'm a little late to the party, but I found your channel on the 3D printed car tire you did recently and have been enjoying the video playbacks since. Keep following the rabbit holes! We are genuinely curious lol
I've seen lots of things on UA-cam, I don't think I've seen anyone make bespoke bullet proof glass. Please continue down this physics rabbit hole. For my own enjoyment.
14:09 it's 5.56 OR .223. and GREEN TIP = Green-tip ammunition is most common in 5.56/. 223 Rem caliber and is mainly designed for use with the AR platform. These rounds were originally considered controversial, as they meet one of the criteria of the federal definition of armor-piercing ammunition.
What? Why would you re-anneal toughened glass? Any glass supplier will be able to provide annealled glass, it's just standard glass. Surely that would be cheaper/faster/easier.
Any polycarbonate layer will generally be on the inside to prevent spalling. If you are in an armored car that gets shot up, you dont want glass shards flying around the cabin.
Shoot the glass side. The reason is the poly-c side is used to prevent glass flying at the people it is designed to protect. Of course you can put plexi on both sides, but you could put tempered glass over the plexi on both sides for clarity and scratch resistance.
The back layer on commercial bulletproof glass is poly to collect spalling. If glass side was the back it'd send shrapnel in - it is visible in the first successful piece you made! E: I needed to watch like a minute more! HAH!
I remember hearing stories about how the US military had a lot of excess Ballistic glass and not enough armor plate for their vehicles... so they just used the glass on the doors to stop the IED's with the glass/tin penetrators (Explosion make the metal/glass form into a superheated cone that can punch through armored plate) anyway it worked well enough until soldiers were posting stuff on social media and the bad guys knew the thickness and penetration so they just tweaked the design. Anyway, not sure why I remembered this specifically, maybe that Ballistic glass story impressed me and that stays with me to this day.
You're supposed to shoot the glass side. If you shoot the polycarbonate side, the glass explodes off the other side and into the face of the person you were trying to shoot. Aside from that, I think you may have had better test results if you had bolted the glass into a steel frame that compresses the glass together as well, since the glass would be installed into a building in a similar way. It would help to keep the layers from separating when you shoot it.
outside view is for fancy only. try metal sheet walls (steel container, can) filled with concrete or plascrete (resin + sand in concrete style mix), yep bulletproof glass is just concrete block roughly. try kinetic sand inside a steel can.
As a guy who works for in a glass shop, taking tempered glass and making it into annealed its the expensive and hard way. 3/8 plate glass shouldn't be hard to get. Even 1/2 shouldn't be hard to find.
Great Video Guys if you can understand how armor platting is made on a WW2 Battleship built proof glass is made almost in the same manor with different types of layers of protection ..

Hello how are you all? Great vodeo I just want to ask when he is filling resin between two sheets of glass how is he separating the glass from each other to give space to fill the resin? Thank you all good day!
I wonder how it would go if one were to alternate between layers of acrylate and glass, so as to have a cushioning effect between layers and thereby offer some form of damping effect.
Why does the glass need to be annealed and not tempered to make the BP glass? I saw bim explaining the difference and how to make tempered be annealed, but not WHY it needs to be annealed for this use

@@nickc5610Im guessing you have never cleaned broken glass. Even on a high vis smooth floor its near impossible to get all the tiny, splinter sized, shards picked up. Now try in snow and dirt with leaves... exactly. Unless they industrial vacuumed the whole area, its likely glass remained. They could have done this in an indoor range where it would be contained and easier to clean. They did this outside because they didnt want to pay a range any fees. Also, just because someone says they did something, doesnt mean they did. People lie. All the time. Especially to seem nice and/or like a good person. Welcome to humanity.

So your saying it should be possible to make a bulletproof cyber truck if Tesla tried harder?
Framing the glass and also having polycarbonate on both sides would have really helped it stay together. Just incase theres a next time.
Yeah what I was noticing. The materials are good, but there's no outer frame to really secure them (it being a small surface area doesn't help on shock absorption either, but can't expect him making a huge panel)
I'm pretty sure bulletproof glass is usually held in place. Therefore, does not expend momentum moving

fun fact for not the gun junkies, green tips are armor piercing rounds with a steel core, really good at penetrating things

You should frame the glass first to hold all layer together and prevent the glass from flying around

Woah you’re too kind!
The good bulletproof glass is aluminum, oxygen, and nitrogen (ALON/aluminum oxynitride) and glass layered.
you should make a suit of armor out of bulletproof glass
