So there it is. Only thing I don't like is the forearms plates sliding off if I don't tighten the straps properly. Maybe I can add a type of rubber cord connecting the upper forearm strap to the lower shoulder strap.

Missing gauntlets, hands feel vulnerable. No response from both youtube guys to make a test vid, shooting test panels made with the same method I did, a heavy and a light type of glass filament weave.

Just wanted to show results. Ask questions if you want. Will only post a new thread after this one if a test video comes out.

about 25kg. Can't test am german noguns fag, asked the youtuber techthisoutmeow and zna productions to test my method. Various types of glass filament layers with epoxy/polyester resin can be made into 3a armor. Still waiting for a response. It's good against slashing and bashing too. Doubt a professional samurai with a ten thousand fold katana can cut trough a full plate.
>>2509382
see pic rel for basic idea that applies to all pieces I made. I dunno how you would print that. Gonna paste my an explanation

It consists of a backer plate (9 light + 9 heavy layers), porcelain shards and a topper (3 +3) encasing the ceramics. Wanted to use 2 offset layers of ceramics, instead I placed the first and additional shards on what I deemed crucial parts of the armor.

This is the basic method for all armor parts I made, a full plate with porcelain for my mask, forearms and torso, the rest consists only of the backer type plate, 18 layers of sandwiched light and heavy glass cloth.

Made a visor from 1cm thick polycarbonat. Went trough some trial and error while attempting to heat bend it. Made a bubble free curved piece with our oven, the trick is to heat it up to 150c first and frequently open the door to let out steam, after a while turn it up to 175c. I want to thank thermoplastic anon for that info again. Another thanks to soap bar anon, scrub a bar of soap then wipe with a dry towel on glassy surfaces like glasses you don't want to fog up with your breath, it really works.

My first thought is that your chestplate seems low, maybe it's just covered by fabric or something but is there a really big gap around your collarbones?
For gauntlets, try looking at hema gloves. There's a bunch of different styles and will have different strengths but they're all generally supposed to protect you from fat nerds getting overexcited and smashing your knuckles with their shiny new feder.

such a mask that sits straight on your face might be fine for smaller cuts and impacts but a serious blow is just going to crush whatever's underneath even if it doesn't penetrate.
i would have taken some inspiration from a houndskull bascinet and give it some conical shape at the front to deflect blows and some padding as well
same goes for your chest
but overall seems like it offers legit protection
also there are airsoft goggles out there that have a fine metal mesh to prevent small pieces of plastic getting through, maybe could be an option for the eyeslits and breathing holes. presumably better than nothing

The 3d printer would likely be more expensive, but overall, with added in layers like you have, it would be hard as fuck with ceramic materials or carbon fiber. Also thinking about adding in hollow spaces to stop 556 rounds from going through, relying on them to shatter and break apart on the first layer and empty space.

yes breastplate and upper legs are bit low, didn't tight them properly. Said to my wife to take pics. For gloves I think I got it now, simply the work gloves with cut off fingertips and above that my welding gloves. Should be good enough to hold my polehammer and still offer some protection.

I can breath just fine, two holes for nostrils. Can also breath with mouth (yada yada I'm a mouthbreather) as air comes in/out trough eyeholes which was a problem itself as it foged up my visor, got it fixed with soap.
>>2509676
show examples of how this could be made, 3d printers are definetevly cool, but I noticed a trend where people will simply assume that a printer can print anything. How would you measure out your face this way? I did with simple gypsum bandages. And then print it how? Carbon fibres? For costs, a 33cm x 33cm rectangle plate costs about 15€ in material costs, the groin plate has this size. thats 9 + 9 patches of the heavy a d light glass filament. 1m2 can be cut into 9 patches. 1m2 of glass weave costs about 3-5€, so about 3 for the light and 5 for the heavy, 8€ total for the weave. Epoxy resin can be expensive, cheapest I found was 11€ per kg. for a 33cmx33cm plate with 18 layers of mixed weaves I needed 750g of epoxy, so about 7-9€ or something. Now you got a basic plate for what 15-20€. Porcelain is the best worst ceramic for balistic protection, you can source that for free. Add another glass weave for spalling protection above that to stop porcelain fragments from flying everywhere and boom you got a decent plate I'd say. 25€ max.

I imagine you can just scan your face and fit it to you personally with cad programs. Solidworks be like that. Now, some of them are brittle, which makes it shatter, which is useful when dispersing forces like being struck by bullets.

I should've put on the torso plates correctly for the pic, front plate sits higher and back plate lower. There isn't much room actually, my mask's chin is in contact with the top edge of the breastplate. Looking down is difficult this way. For sideplates, I feel I am at a limit with 25kg already. Walking around like a clunky knight, every step makes 'clank' from the groin plate slamming against the leg plates. Maybe I gonna make some simple side plate pieces and use looped straps, looping them in the strap of the backplate. Similiar to the groin piece

also: invest in some orthopedic knee sleeves and orthopedic lumbar belt. it stabilizes the joints and helps to keep posture, even though it can be a little stuffy. it greatly reduces the risk for injury when wearing heavy plate though.

and look into how medieval armors straps and contact surfaces are placed. they had weight distribution down to routine. like letting the chest plate rest on the hip supported belt instead of solemly on the shoulders, and letting the shins rest on the boot.

good info, didnt consider these orthopedic products yet. Somewhat similiar thought I had was, you could stud protective gear for skateboarding etc. with the glass filament. I did so with the helmet.

The torso plates connect over the shoulder and sideways like a belt, I can let one connection stay open and it still fits. Shins also slide on boot unless I tighten the straps too strong, if I'm not wearing high shaft boots, it's uncomfortable to wear this way.

the protective gear part is a different beast. the orthopaedic gear is to prevent knee injury from missteps or non optimal posture. same goes for the lumbar belt.
even the cheap aldi versions do their job.

joint injury is the number one eliminator of modern troops.

for the fit: add a padded comfortable belt strap with some semi-rigid plate support. this way you circumvent the spine being loaded and free your lungs more. putting padding on the shin lower side, so it rests better on the shoe, can make the bug a feature.

some light knee pads could help with the armor and hard knuckle or sand gloves would add some necessary hand protection.

for the groin plate: try to cut it int an inverted trapezoid (basicly upside down chest plate shape). then it moves more easily when walking. the two removed pieces can be added as belt flaps/ armor skirt pieces.

the force of a bullet spread over a whole chest is not an issue. the only reason bullets are so deadly is that they concentrate all the force on a small area, creating preasure that rips through objects.
the force of a handgun bullet is identical to the felt recoil, but basicly put into a nail instead of a hammer grip.
people only fall over when shot in the breastplate because they get jumped from the sudden impact, noise and realization.
soft armor leaves bruises, hard armor does not unless it bends severely.

shotgun slugs have more impact punch, but less penetration due to wider projectiles. they can knock your wind out like the recoil can hurt your shoulder when held improperly.

good question. A knife is easily stopped for sure, I tested that. But dunno how many layers I could decrease of my armor to still achieve this.

In some ealier thread I linked a work of a cosplayer who made a stab resistant batman suit in a similiar fashion. Got lots of good ideas about moddeling armor etc. from cosplayers and furries, not that I like this kind of hobby.

you're confusing force with impulse. a bullet accelerates through the barrel while the time involved for a bullet to hit an object is way shorter. F=dP/dT
force of impact is way higher but impulse remains the same. so you're indeed correct that getting hit by a bullet isn't going to knock you over

yes see pic rel, at first I wantedv to integrate the nails trough the cloth before applying epoxy. Didn't work. Instead a strap of steel mesh, nails trough openings. 10 nails on both forearms and shins. I oxidised them prior in a citric acid solution but they started to rust actuallly.

As someone who's made a lot of cheap plastic armour, this is honestly pretty shit.
What are you planning to do with it? If you're actually planning to get hit by anything with some force, check out how people in the SCA make their armour. Pic rel is a really common example.

Or even easier, just buy a full-coverage zoombang and layer up some hard armour on pointy bones. It also scales well if you want to put a ballistic plate on your chest or back, depending on who you're planning to fight.

the energy the pistol withholds and then releases as recoil into the hand of the shooter is equal to the energy of the bullet. its just spread out over a larger area and, due to inertia, time.
what makes bullets so devastating is the pressure spike they cause.
a material that can resist that preasure, spread it ove an area, and has acushion zone that spreads the energy over time has the same reduction effect as the felt recoil of the pistol.

For maximum efficiency, cut the fat out and chop it into ~1cm cubes. Put it in a pot with some water to cover and heat it to a simmer. After a few hours all the fatty acids will be rendered out of the tissue, then you sift the chunks out and let the liquids harden. The fat layer separates and floats on the water. To clean it just scrape the grimy bits off the bottom of the solid fat layer and put it back in a pot with fresh water and a generous handful of salt, bring it to a simmer and stir it a bit, let it cool and repeat until pearly white. Finally melt the fat down and insert a wick. There you go, odorless human candle.
Human fat is about 7700kcal/kg which is a lot better than wood pellets which generally sit around 4300kcal/kg. You only need a small fraction of that energy to refine it.

A bullet proof vest and a plate carrier are two separate things. A vest will bend and absorb a lot more energy, while a plate carrier and other hard surfaces like OPs will not. When I was in Afghanistan I did get shot, It didnt knock the wind out of me, I can't say it felt like a sledgehammer because I've never been hit with one but it was pretty hard. Also depending on round and what type of armor, be it ceramic or steel, the Cermic can take several shots before its fully compromised, a steel one can easily take more unless the round is a very high velocity round.

But I'll ask /diy/ this first, do you think I could make some comparative level iii+ or even level iii plates by using alternating layers of Teflon and fiberglass and instead of fiberglass resin using bedliner like rhinoliner and making 5/8 or 3/4in thick?

To make soap all you need to do is weigh your human tallow, then bring it to about 50°C. Take 26.82% of your fat weight in distilled water and 13.41% in pure lye and dissolve it in the water (do it with good ventilation or die). It will heat to almost boiling so let the mixture come down to around 50°C also, then dump it in the liquid fat and blend it with an immersion blender until it turns into a sort of paste. Scoop that out into whatever mold you like and let it sit for a day, then demold it and let it air dry for 2-4 weeks.

Why teflon? Why bedliner for bonding? Line X actually is bombproof, mythbusters made a vid about that, discussed this in thread #1 or 2 I think. The company by the same name actually has a specialized type of coating called pax- something. They use that for bombproofing government buildings. But you can't simply buy either of these products in a can. A shame. Only certified paintshops who are in contract with Line - X get that stuff and are allowed to coat projects wih it.

For the teflon, I just don't know what it would acclompish. I've seen a vid where a dude made a pauldron with glass filament + carbon fibre layers. But carbon sucks. Glass fibre cloth is simply the cheapest.

I wrote ZNA productions and techthisoutmeow multiple times, donated to their patreon. Wanted them to build and shoot test panels with my method. Mentioning it again, 9 light + 9 heavy layers and additionally porcelain + another 3 heavy and 3 light ontop. No further responses for about two months or so.

But thankfully a german hansguns offered to test it for me, I'll be sending him 2 such testpanels after xmas. I've gained some doubts of the success of my plates delivering what I hope for, because I did something different. I didn't vacuum press the plates during curing. My theory is, the epoxy itself should stay where it is and not be pressed out excessively. Further, I think a pressed conventional plate has it disadvantages too. The layers are already then pressed together and it' s maybe easier to penetrate them this way.

Only live tests will show if my theoretical method has advantages over singular type of weave pressed plates. If I had something like military interest funding, I'd research this matter more troughly, but I'm a literal neet lmao.

thats retention of impulse. it lacks the inclussion of area and, through a lack of an inclusion of the time needed for the impulse to be transfered, does not give force or pressure results.

So I actually made a plate like this when I was a teenager. I took a piece of polycarbonate, placed ceramic tiles on top and then laminated the whole thing with many layers of fiberglass and polyester resin. Then I went to a gunfag board and asked some one to shoot it for me.

The results were not good, basically the only thing that didn't penetrate fully was .22LR. I don't remember exactly what he shot it with but I recovered the jacket of a large caliber pistol, possibly 45ACP and a small rifle round, most likely .223. Simply put, ceramic tiles are not hard enough to stop rifle rounds and while they may be able to fragment pistol rounds, they then turn into shrapnel that blows right through the backing. The whole thing was too stiff to work even as 3A armor and while polycarbonate is very tough, it cannot withstand the high impulse of a bullet impact, it basically tore open like a flap and let everything through.

Duh, actual armor has one big plate that shatters when hit. That's a big part of how it helps dissipate the energy and stop the round, a bunch of little pieces in epoxy or whatever would never have the same affect. You'd probably be better off using a whole ceramic tile but even then I'm betting it's going to be massively different than a real plate.

One of the best performing vests is dragonskin which has many small overlapping plates of a hard ceramic glued between layers of woven fiber. The advantage of this armor is that it can take multiple hits where a single hard plate is useless after one since the whole thing shatters.

>>2526402
Because the selling point of polycarbonate is that it basically doesn't break, you can poke holes through but it wasn't supposed to rip apart. My thinking was that the ceramic catches the bullet and then distributes the impact over the polycarbonate which should stop the tile from penetrating through. I didn't know at the time that materials become very different depending on the speed of an impact. I think it was 1/4" thick. It was clay tiles like you would use to pave a walkway.

ah i didnt see the backplate, thats pretty well done
i still think you should try to lace your armor to your clothes, get a padded jack like in >>2527798 because when you get shot even more of the force of the bullet will be dispersed, and will prevent bruising
also, i think you should make a second helmet like pic rel, but only use breaths at the bottom
this design has more of a chance of glancing bullets off the side, and if a bullet catches it, instead of the mask being smashed into your face it'll be much more dispersed
also, it integrates neck protection into it
alternatively a frog mouth helmet would be good, and a close helmet would be ideal since they were used specifically to stop early musket fire, but i dont think that can be made easily with your methods

In fact kevlar can be made using asbestos as fiber and male blue whale cum as glue

Even if it protected you, your limbs would be rendered inoperable when you're hit. Those suits are meant for shrapnel. I would just go with a regular vest. It protects your vital organs, it's all you need. And no, the chinese face armor will not protect you from bullets, even if it did, your face would be busted up to all hell, and in all reality, you'd be knocked out cold.

laminated the 2 test plates, they're half length of a DIN 4 sheet in size. Will cut the edges clean in 2 days after curing. One of those will be improved with porcelain and few more glass cloth layers. In about 5 days it should be completed. I will also add straps with bolts.

yes

lateley been thinking about how to make full body shrapnel protection for children. My idea with hard plates in a front- and backpack + helmet don't cover enough. Thought about making a type of poncho or hooded cloak, without epoxy. But fiberglass itches. Maybe sew it inside of normal cloth or coated fiberglass. Then a helmet with an afixed face visor. Gonna look into how many layers should be enough to protect against random debris from explosions. That UMHWP stuff sure sounds great, but I can't find that cheap on ebay. Fiberglass is simply the cheapest by far. Aramid is another option, but 10 times as expensive.

Gonna cut the test plates tonight eventually, layering the porcelain and adhere topper on one

BAM! Shrapnel protection for children. Reading about it on https://wikipedia.org/wiki/Flak_jacket

During the Korean and Vietnam wars, the flak jacket was changed and the manganese steel plates were replaced by other materials.[5] The U.S. Army's vests (Body Armor, Fragmentation Protective, Vest M69) weighed under eight pounds and were made of 12 layers of ballistic nylon. The vests used by the U.S. Marines (Vest, Armored M-1955) weighed more than ten pounds and were a combination of ballistic nylon layers and fiberglass plates known as Doron.[3] Doron was made of fiberglass fibers placed in an ethyl cellulose resin under high pressure. It was named after then-Colonel Georges F. Doriot, then director of the Military Planning Division, Office of the Quartermaster General.[2]

The generation of armor developed in the 1970s through the National Institute of Justice incorporated layers of soft armor in the form of DuPont’s Kevlar fabric, which has since become synonymous with ballistic protection and a general term used for several similar (aramid-based) materials.[6]

and that's from the 70s, materials should've improved by now significantly. 12 layers of the 270g/m2 fiberglass I worked with should be good. Additionally studing a children bicycle helmet, hard plates for backpacks. Seriously where is my nobel peace price.

>> No.2532457

I am a genius. It worked, first try. 2 cotton cloth sheets, bit larger. 12 fiberglas sheets. Placed the glas on the first cloth and made the first stitch to keep it in place. Worked perfectly, needle didn't break, thread didn't snap, didn't need to pedal slow, neither crank it by hand.

the corners were more difficult for whatever reason (I think its the weave direction), one needle broke, thread also snapped a few times, thus the ugly lines. Had to hand crank the wheel.

All in all I am very pleased. /k /fa /diy/sew and /diy/qtdndtot were no help. Couldn't find any info on sewing fiberglas etc. There is a yt vid with some guy sewing kevlar or something, but just visual footage and no explanation. Will do the porcelain test plate maybe tomorrow if I feel like it.

side note, asked why my refilled fire extuingisher is loosing pressure, it seems stuck at around 6 bar now. This type of bycicle valve is rated for 6 bar, maybe it means max pressure before leaking air? There are 2 different types of valves I could get, standard car type and french type, the first having max 10 and second 15 bar or something. But then again I only got a 10 bar pump and it struggled to reach 8,5 bar on the extuingisher.

Placed porcelain shards and laminated the other test piece, gonna cut the edges in 2 days after curing.

All three test pieces

>top left
sewed 12 layers of the light fiberglass inbetween an inner and outer patch of cotton cloth. It's flexible like thick clothing. Intention is to make a type of cloak a child could wear. So it can't be too heavy and I hope it offers atleast minimal protection, similiar to a Splitterschutzweste (fragmentation vest?). Real Bundeswehr Splitterschutzweste paddings have 12 layers of kevlar appareantly. Theres is this guy 'tactical dad', a german autist with a very informative blog. He has a detailed section about body armor, did tests himself and shot these surplus aftermarket decade old paddings with 9mm fmj, stating more often than not they stop the shots. If my sewed panel can stop atleast one 9mm it'd be more than enough, but I've a slight feeling it won't even handle weaker cartridges. The cloth just doesn't feel thick enough, maybe doubling it to 24 layers would do the trick, but it's intended porpuse of beeing easy to wear for a young child as a full body cloak would be lost.

>top right
not much to say about this, if it stops multiple 9mm it's good. The marked rectangle is where all layers should actually overlap, towards the edge it becomes thinner, as I used some leftover cloths, also the epoxy tends to run to the lowest point. It's 9 heavy + 9 light patches of fiberglass cloth.

>bottom
base plate like top right, porcelain shards encased in 3 heavy + 3 light glass and epoxy. All my previous pieces are curved, this one's flat. Had trouble to tuck in the top glass as I simply tried to lay it back flat on the table. Had to prop it up from the middle section and then place styrofoam piece by piece under it along the edges to get the cloth tucked. I hope it will turn out alright. If it's similiar to 3A all is cool.

After 14 hours the epoxy was still workable. Sticky surface. Was able to turn the cloth around on the entire edge.

My wife asked me about my progress, while explaining I think I got a good explanation of my method. Instead of applying pressure during curing, I let it rest. I imagine it like a towel hanging in the air, the weave is relaxed and stabbing it the towel will conform to the knife before it rips trough. If you stretch the same towel from all sides, the fibers are already under stress and one can stab it more easliy. More factors come to mind, for example having the surface covered while pressing it cuts of the workpiece from air which maybe intrerfers with the curing process. Can epoxy cure in a vacuum?

Regardless, only practice will show

they really look like something I could easily work with, replacing the (I asume) soft padding with similiar sized pieces of epoxid fiberglass. But before I continue on building anything, I gonna wait for the test results. I have almost no light weave and only a bit more heavy weave leftover. Half of the large epoxy containe, about 5kg. If tests are promising I will continue with gloves, children poncho and such. If all of the test pieces suck, 4chan will never hear from me again.

I'll give the plates to delivery tomorrow
