When you are building a plate you need two things hardness and tensile strength. You want high hardness on the face mohs 6 or higher. Tile, tool steel, high carbon steel, alumina oxide(grinder discs) glass. You want tensile strength on the back. HDPE, fiberglass, nylon, hemp, aluminum, mild steel. Horse mat.

I just tested many strikeface options and the performance. The video should be out this week. Overall I agree with what you said and have already made a few plates that can handle high threats. I’m now wondering what is really needed for certain lower threats, very similar to the different NIJ levels. I will work with each item to find a strong strikeface and backing with lower weight and cost to hopefully put something together.

Some of this could be due to 'resonance' , Yamaha developed the first Real motorcycle-tyres , they found shorter chopped-mat material absorbed impact better than long-fiber materials , this started modern tyre-technology . They applied their knowledge from musical-instrument making and piano-frame-casting with effects on frquency-distortion .

I like your idea of landscape fabric! There are several thickness grades of landscape fabric, I used the thickest I could find at Menards for a french drain install last fall. While the fabric is 'non-woven' there may be a 'preferential nap direction' from the manufacturing process, even just tugging and stretching that happens when they roll it onto spools -- so alternate cut direction of panels from the roll as you stack layers like you see in plywood. Second is using landscape fabric+fiberglass+landscape fabric sandwiched and glued together or try more thinner components like three fiberglass shuffled between four landscape fabric layers.

You make a valid point, but there’s steel core ammo out there. You have to have some kind of impact plate to absorb all of that kinetic energy and not spall. You could add a layer of polyethylene (like the blue poly drums), to absorb the impact and prevent any if not all of the spalling from the bullet. If someone has any welding experience and the equipment, one could hard face weld a steel plate; hard facing is a welding process of welding mild steel with a hard facing electrode, basically welding an armor plate, that is impact and abrasion resistant), and combine that plate with fiberglass or Tyvek, or both, and you’d basically have military grade ballistic plates. Don’t take my comments as “The Gospel”. It should be tested extensively with ALL calibers of ammunition to get a 100% TRUE AND ACCURATE TEST with valid evidence results.

Fantastic idea

I'd encourage a multi-layup sandwiching thin steel (1/8") and fiberglass. But instead of laying it flat as most folks do, try building it in various layers from right to left. So a flat layer of glass as a 'base' (closest to your person), then a diagonal build from left to right (or from the centerline outward at opposing angles) sandwiching fiberglass and steel such that the steel almost 'overlaps'. This is difficult to describe in text, but the theory is tank armor. When they were designing it they found that using thick enough plating to stop larger rounds would make the tank too heavy. Some brilliant engineer realized that if the rounds were to strike a thinner piece of metal at an angle, the plate was effectively thicker since the round was traveling through the material at something other than a 90 degree angle. That's what you're replicating with this, however we're adding another element by sandwiching it with a woven material. The woven material works best because it's taking the energy of the round and distributing it along many paths which are expanding and moving. The whole idea of effective body armor is energy management. You're trying to disperse the energy of the round into the material, so in a sense, the more 'squidgy' a material is, the more effectively it'll do that. Lots of folks use expanding rounds, which is actually beneficial since they're LESS likely to penetrate body armor than ball ammo is. By layering 'base layers' and angled layers, you're creating different load paths. The angled steel should, in theory, help to trap the fragmentation of the round and redirect the energy outward across the armor more effectively than just putting woven layers on top of eachother on the same plane. Feel free to get in touch for some better visual data if you'd like. This stuff interests me.

This would be the build: Face plate of 5mm Titanium, 1 layer of what ever medium (Fiberglass & resin, or other), a 1/8" uhmw sheet, and then another layer of a chosen medium, all equaling 1" or 1 1/8" The Titanium would cause the deformation of the nose of the bullet, the first layer of medium would slow it down, the uhmw won't do almost anything against penetration BUT it is extremely self healing so it will constrict the bullet as it passes through it (and most likely stop it, then the last layer of medium will stop the bullet in cooperation with the uhmw. I would love to see the result its just that I do a lot of other things, but what you are doing is very cool. Btw, the uhmw and titanium sheet can be found on amazon.

There is lots of discussion about hardness and strength, but maybe toughness deserves more consideration. It's how much energy a material can absorb without breaking. You can think of it as a combination of low hardness and high strength. So, high hardness at the strike plate to deform and deflect, then a tough layer to absorb energy from the deformed/fragmented remnant, and finally a high strength layer to reflect the remaining energy back through the tough layer without deforming too much toward the wearer. I apologize if this is something everyone already knows and has covered. I'm just thinking about toughness as an independent material property that has a role here.

Ceramic is the key here. Ditch that steel. It adds unnecessary weight for minimal protection. Rubber over tile, tile over fiberglass, all painted with bed liner after being vacuum sealed to cure. Buy in bulk and make plates for about $40 a piece. The ceramic busts up the bullets and the fiberglass catches the shards. Try building angled plates. That's the next frontier in home armor. The methodology comes from tank armor in WW2.

Putting a tile layer over the front of fiberglass or other plate material that can stop up to 44 magnum could easily bump it up to level III or even level III+.

tightly weave cobalt chrome drill bits (maybe you can get them used?) into kevlar or fiberglass, vacuum bag it, or weld(brazing may be better) them into a multiple layer plate with crossed grains like plywood. it should fragment the steel core of an AP round; add a backing layer of composite to catch the fragments..

Add a front layer of 16ga steel, and a layer of 1/4" plywood on the back to stop deformation/shrapnel

Consider the 16 gauge laminated to the 25 fiberglass. With fiberglass in front it should prevent spall and the metal base should enhance survivability of a hit. Remember the deformation of a round is capable of killing a wearer.

Gage steel would minimally increase weight but cause a HV round to expend tremendous energy when it contacted the metal. At that point the layers of fiberglass should have slowed the round measurably, hopefully with enough deformation of the end to decrease the chance of penetration of the metal plate

Unfortunately I can't. I was about 5yrs ago when I was researching the American industrial hemp/ industry before prohibition. I learned that Ford built the auto-body of his cars with a material derived from industrial hemp and it was tested to be stronger and lighter than steel. If i remember correctly this same hemp material was used in cement, bricks and cinder blocks producing extremely strong and durable products.

A number of common materials are, weight for weight, stronger than steel. At least in terms of tensile strength. In the realm of woven fabrics, there are Polyester, Nylon, fibreglass fabric and silk to name but a few. At least 3 of them can be combined with resins. But hemp and Jute/Burlap are plant based fabrics, which whilst stronger than cotton, fall short of the former 4. Again, they can be combined with resins.

Bondo doesn't have the fiber integrity. But some stuff I always heard refered to as "kitty hair" definitely would. It is coarse chopped fiberglass in a resin that is very tough. I would think a first layer that would promote the expansion would make thinner armor more effective. Maybe a layer or two of fiberglass woven then laminated over top a second layer of UHMW then a layer of mild steel backed up by the landscape fabric. The worst part about this would be delamination. The combination of these materials could make a lighter as well much more tough "plate" that isn't cold or hot depending on environment but also useful. Then again there is also another idea that I had about thermal management. In the age of thermal imaging an armor that displaces heat or absorbs it to your advantage could be had using simple heat transfer. You can't hit what you don't see...

Put a thick coating of Rhino liner on as a final covering

Maybe put some thin hardy backer board wrapped in the landscape fabric for a test. Layered

Wrecked cars/trucks, the airbags are a free source of a great material.

i think landscaping fabric is the same material used for making sacks for rice/beans/grain. Nylon maybe? Perhaps do a landscaping hybrid stack w/fiberglass finish overlay or middle fiberglass. Milk gallons are made of polyethylene (maybe not high molecule) but i'd be curious how a stack of milk gallon layers measures up.

Just having a think...You could laminate a thin layer of steel on the front side. The idea is that this layer absorbs some of the kinetic energy of the projectile, but more importantly, it deforms the projectile which makes it worse at penetrating the bulk armour layer.

Brazil has done some material science research on inexpensive plant fibers for ballistic armor. Jute (and burlap) does very well. The only issue with something like burlap is the need for some kind of apparatus to compress and shape the resin-layered fabric. It absorbs a lot of resin and is thick if not tightly compressed. It can be heavy but it was found to be a very good replacement for kevlar and other expensive ballistic fabrics.

Put the steel sheet in between both the woven n zipper them up in a chest pouch to keepem together.

I wonder about using epoxy instead of polyester resin. It is much nicer to work with. Trying to squeeze out excess resin will make it lighter and thinner for the same strength. Many boat builders vacuum bag hulls to acquire higher strength to weight ratios. Also possibly woven roving in carbon fiber for the back layer since it has high strength but shatters with impact. Small pieces aren’t expensive.

You could use a combination of fiberglass and steel plate to stop .44 magnum. But, you need to also test with high power rifles. There’s a lot of ammo out there that have steel and tungsten carbide steel cores that will punch right through those plates. You’ve got the right idea, but you also have to include rifles in your tests. I’ve seen some 7.62x39, and 7.62x54R ammo that have steel cores in them. So, everyone out there, don’t assume that if you make these plates for your own protection that you’d have bulletproof plates, because there’s ammo out there that WILL defeat those plates. Please don’t think that I’m a know-it-all. I’m speaking from experience and I’m looking out for your own personal safety.

You are right that 750 to 1000 dollar armour is not the way to go cash wise but the Chinese soft and hard armour NIJ level three A 11x14 plates at fifty dollars each opens up a new option as one hard plate will stop handguns and a soft plate behind it would be double indemnity if you are shot with a rifle, maybe? DIY would probably need a mix of different materials and layers to affect the bullet enough to make it wobble and alter trajectory plus slow it right down - an awful lot of experiment I would think using materials cut straight to resist and others cut on the bias to stretch and bend. A big task! The inventor's algorithm is simple enough - we wish to slow and eventually stop a projectile against or even within the vest without allowing a dangerous amount of blunt trauma through to the human body. I have a level 3A UK police bullet and anti stab spike proof vest that is both soft and hard! Kevlar sheets with stainless steel disks spread out like fish scales. Great design as it stops the projectile and allows the impact force to dissipate through the soft material. Interesting that as humans we use hair as our natural armour while birds use feathers even to keep out a hornet's sting. Francis of Assisi once gave a pile of his hair to a villager because his adobe wall kept falling down and the new mix plus the hair turned out like really hard stone and solved the problem. I only mention these things as somewhere along the line by trial and error you are very liable to find the ideal combination that creates a superior vest.

Have you seen the strapping that is replacing steel product banding? Green, very tough plastic. I bet you could get all you want from contractors wanting to get rid of it as opposed to recycling? or trash. Bricks, and pavers use a lot of it. I was thinking it could be a big plus over HDPP, or as several layers between your unwoven lawn fabric.

Landscaping fabric, metal and closest to body the fiberglass. THAT might give you some nice resistance, but will be quite big and probably heavy.

intresting . Kentucky ballstics shot up some stretch armstrongs and they were quite resistant , so whatever that stuff is inside them would make a good test if you can find out what it is .

What is even better is it trapped the 1st projectile reducing the shrapnel

also older dates (i forget which year) Canadian nickels 99.99% pure nickel sandwiched within at least one layer

It would be interesting to know the amount of energy delivered to the plates. It may not be the bullet that does you in but instead the crushing blow to one's internals. I believe I once read of a flexible armor called "Dragon scales". I wonder what became of that concept. Good show.

You are correct. Even with commercially produced for bulletproof vest with the best engineering in the world to get the policeman if you get shot the vest will stop the penetration, but the flex of the vest will distribute that energy, and if it can't get spread out big enough it'll snap a rib or something.

Yeah there's so much involved in a collision that mirror energy doesn't catch it all you have to consider linear momentum. You could get hit with a fairly high energy round that didn't have a lot of mass and it may deflect or shatter and not do much damage behind the armor. They used to have an 80 caliber cap and ball Derringer with a 2 inch barrel. You could pull it out of your pocket and shoot it up through an oak table top the ball would go through the oak table top and hit another card player and kill him. If you got hit on a bulletproof vest with that 80 caliber ball it could crack a couple of ribs and kill you easily especially if you were leaning against the wall so you couldn't move when the ball hit you.

An idea to add.. Soft panels armor in front of a reduction of layers-hard armor. In other words, take a 2-A soft armor and marry it to a 2-A hard armor.

would steel be better up front instead of a backer? get deformation so the woven backer catches the rough edges?

The armor may stop the projectile and keep it from penetrating the body, but the force will do damage to the underlying organs, especially the hollow ones.
