This is a specifically bullet proof statement. Paying off DOJ does nothing to change the fact that testing proves resistance.
why do that when they could just send machines into dangerous areas to kill with more efficiency and lower risk than a human could, except in particularly complex situations
Smaller target, less overall armor required. Adult male sized power armor would be heavy as frick, but with an infant you only really need to give it an egg of tank armor placed inside an exoskeleton.
Genius.
Robots can't be trusted with firearms and warfare. They don't know mercy, they don't understand the finality of death. Behind every trigger pull must be a human soul, otherwise we will forget the terrible cost associated with war.
That's why they banned abortion. Shore up the troop numbers. "GI" now stands for Gerber Infantry. Government owned and trained from birth to kill for Uncle Sam since mommy and daddy sold them for gas and crack.

I would go with option 2 for making proper armor. Official LIBA has locking pieces between each ball (which is why cylinders would be better for civies). You can order everything from McMaster carr. Its hard to beat the epoxy way though since there are so many types one has to work well for this. I've also supposed you could use a plastic(or metal) chicken wire mesh as a lattice before
>melted milk jugs(uhwmpe)
lol no, they're LDPE, HDPE, or PET. If you want high modulus you're going to have to buy a sheet.
I realized my mistake after I had already posted it. HDPE will still work in a pinch but not as well obviously, this is to just catch spall and hold it together which it will do just fine.
Well, then you've got the problem of melting your bottles without cooking them. I used to work in the plastics industry and we gave up on them in our process, cost more in scrappage than we were saving and since that was then contaminated it fricked the whole recycle loop.
Cleaned bottle tops on the other hand, turns out you can just shred them directly into a hopper with no further processing. Good stuff.
I would give it a miss myself.
Ceramic and UHMWPE.
And then perhaps in the future soft gel-like materials similar to D30 that harden on impact, they are just not durable enough to stop bullets yet.
Although Silicone carbide coupled with Aramid or Dyneema are already pretty damn fascinating in what they can accomplish relative to their weight.
yes. the idea being that the sum of the pellets makes up a composite strike face and each pellet is mostly unaffected by adjacent hits making for extreme multi-hit ability, one of monolithic ceramics' shortcomings. the gaps are also compensated for, as they're too small for bullets to pass through without being shattered and destabilized by even a glancing hit on the ceramic and are caught by the backer, typically polyethylene or an aramid of some kind
>each pellet is mostly unaffected by adjacent hits making for extreme multi-hit ability, one of monolithic ceramics' shortcomings.
Modern ceramic has adequate multi hit capability. I don't understand why people are so concerned about a plate surviving 7 .308 AP rounds or whatever. If your plate ate that much I'm guessing your arms, legs, torso and head got shredded. for what plates cost you just buy a new one after you get shot.
These would be oriented so their long axis is perpendicular to incoming fire, right?

Do they make hexagonal ones? I could see that helping with any gap issues between cylinders. Of course just choosing a small enough cylinder size to make gaps smaller would help as well.
Yeah, but the caveat is that they aren't commonly sold as ball mill grinding media like cylinders and satellites. you would need to have them produced for you. Easy if you're a corporation, difficult if you're some dork in a basement
part of the effectiveness of the pellets is that individually they're about as thick as a comparable monolithic plate. start playing with thickness and stacking without compensating elsewhere in the design and you might end up with an unreliable plate. it's feasible with something like

Is it just as heavy as a normal plate though?

depends on construction really. theoretically a plate consisting of only ceramic+epoxy/whatever would be lighter than a standard plate but LIBA requires a backer of some sort
Or you could just take smaller spheres and lay them offset to block all of the holes in two layers. Cylinders wouldn't work as well that way. Two layers though would make it really quite thick while also shrinking the size of each ceramic ball. That's not great because I remember another anon said a couple months ago when this came up that the ceramic needs to be a certain minimum size to deal with all of the bullet sizes

Thank God some people other than me are thinking about this. It's literally so easy and cheap its unbelievable. You buy like 100lbs of ceramic media+ epoxy on top of melted milk jugs(uhwmpe) and make enough plate for your whole family and probably your friends.

Literally search ceramic grinding balls/cylinders. It's the exact same material as they use in body armor. You can get alumina, SiC, zirconium, etc. Just make sure you buy the stuff with less fillers for better strike faces.

How about if rather than epoxy you sewed them between two pieces of fabric, make two sheets of that then interlock/overlap them? End result would be flexible, lighter and you wouldn't have to worry about the epoxy cracking and leaving gaps. IIIa soft backer and that should stop an awful lot of threats.
Just remember to put a metal plate behind them, no matter what suspension material you use. It quite literally turns into a claymore if the material you use isn't going to hold the balls in place under extreme force.
It would be better to just use ceramic cylinders with a steel plate backing.
its a sort of in between of steel and ceramics. You get the multi-hit capacity of steel, plus the weight reduction and similar strength to ceramics. The main issue with titanium is the heath transfer so its susceptible to sheer plugging but thats what the polyethylene backer is for
theres a ton of different types of both steel and titanium obviously but when considering the best of both titanium wins out in the case of personal armor (not including costs but dont be poor).
Once everyone has adopted new cartridges that defeat current and near future armor like the 6.8mm we'll probably see everyone ditch body armor again.
It's an endless cycle.
Did you know they have powered exoskeletons, .50 cal rated body armor, and special anti-thermal coating? Any day now they'll start using them in Ukraine and the tides will turn overnight.
Armor is for atheists and fools. Fight until it is your time to go, and then die in peace because you will have done all that was asked of you.
Is it a coincidence that while the West has become more atheistic, armor technology has advanced rapidly? No, it is a direct correlation, because they are afraid to fight and afraid to die.
Improvements in Polyethylene will continue for the next few decades, it is still very very far from reaching its maximum theoretical strength, so expect thinner and lighter soft armor, and the same for plate backers and helmets. The outcome of this is you should see level IV plates close to 3.6lbs standalone, and m-80 ball/ m193 ball helmets weighing what gucci IIIa helmets weigh today.
Ceramics have less exciting prospects for the future, but there should be a steady decline in the price delta between shitty alumina and good silicon carbide and boron carbide.
Boron carbide should see its formula perfected over the next decade, taking away its weakness to tungsten carbide, allowing for lighter weight plates that can handle advanced threats. My thought is something like a 4.5lb standalone that stops Swiss P.
Titanium diboride might see improvements to its production, bringing down cost enugh that it can be mixed in with either silicon or boron carbide in significant fractions, allowing for ultra strong plates. Combined with future backers, you could see 6lb standalone .50bmg AP plates. Absolutely not cheap, but probable.
UHMWPE composites reinforced with fibers is the future. Currently big companies have proprietary research additives they use to optimize the interfacial adhesion of fibers with the polymer to make it mechanically stronger. Some of these additives have insane effects on increasing mechanical and thermal stability and you'll probably see upgrades to armor rolling out in a few years once similar shit hits commercial producers.
t. did research on UHMWPE for a big company
In case you missed it, II and IIIa polyethylene are much thinner than kevlar for the same protection level. Advances in polyethylene are allowing thinner and lighter level IIIs and IVs as well.
That there is no level IV poly plate isnt a coincidence, as a material it cant handle steel core so by default it cant reasonably be made a level IV on its own.
>In case you missed it, II and IIIa polyethylene are much thinner than kevlar for the same protection level.
Yeah but the comparison between hard and soft plate mechanics is so different it's practically apples and oranges.
why don't militaries issue arm and leg protection made out of level 3 UHWPE? should only weigh a few pounds and would protect from a majority of shrapnel aswell as I believe chinesium and stalinium standard issue rounds, no? Especially SWAT and shit like that where they only have to run 100 metres on their mission anyways and are very likely to come up against civilian grade rifles
the thing is 99% of all threats a swat officer would face are gonna be lead fmj, which UHWPE should be capable of stopping. He's not gonna feel the extra 5 pounds either when all he's gonna do is raid a single home after getting there by van.
And even then an UHWMPE level 3 plate should be able to stop commonly issued AP rounds for 5.56/russian equivalent/shrapnel yes? Seems well worth the tradeoff to me atleast, and im surprised there is no offerings for such things at this moment even if only for niche uses.
>Militaries
