It's hard to say for sure but that plate looks like it's made of Ultra High Molecular Weight Polyethylene (UHMWPE) rather than a ceramic material.

[@shepardpolska]

Yeah ceramic plate would be pretty heavy and way too hard for the arrow to stay together or stick in. There usually is a thin layer of kevlar and thick ceramic tiles in those, with more kevlar backing.

The silicon carbide plates are about 15mm thick with about 5mm thick spall liner over them and you're getting close to 4kg each. Not a lot is going through them easily unless you have a heavy machinegun handy They're also quite expensive so it'd be a lot of money to drop with no real tangible benefit to the experiment as we all know arrows and bolts aren't going to penetrate.

[@testing2741]

It's important to note, that's not ceramic plate, but essentially fiberglass. You can homemake that same type of armor with cross-stacked heat blanket material, coated with fiber glass resin, layered repeatedly in hundreds of layers in alternating or radially variating directions, and then cut the dried plate with a band saw or circular saw. Search KZbin for examples of how that is made. Also thats not how ceramic reacts to arrows or knives, it will crack typically.

It would go through 2 of them , its basically a really fast heavy arrow it doesn't behave like a brittle low mass bullet.

[@RobbeSeolh]

always wondered this, also can historicalmechanical artillery (ballistas)penetrate ceramic armour?

[@thecarrot4412]

I think if you were to get an 80ish lb compound bow with the higher mass of full length arrows also you would see higher penetration. Kinetic energy isn't everything when it comes to beating armour. Some 0.22in diameter, 400 grain or so arrows at 320 fps might well make it through.

[@shepardpolska]

This is a plate made of resined plastic, that stops bullets by breaking them down from the shock of high speed impact. No wonder a slow sharp arrow does so well. Contrary to what was said at the start these plates don't have any ceramic tiles. It's just a block of UHMWPE.

[@TestUser-cf4wj]

I just watched a different KZbinr (British guy who colabs with Jöerg sometimes, can't remember his name presently) who did a comparison between a medieval 950 lb draw crossbow and a modern 120 lb draw. The modern sent the bolts much faster but the archaic hit with more force. It was suggested that using an archaic 90 gram bolt in the modern crossbow would yeild forces nearing firearm levels but at crossbow speeds. Slow, heavy and sharp might do the trick.

[@alfonsmarklen1345]

If you could bother doing a follow up on this I would love to see another round with heavier bolt shafts since Tod have shown that penetration has a higher corelation than the kinetic energy so it is possible that the same tip would have more penetration from being attached to bolt with twice as much mass than being shot from a cross bow with double the draw wight. Could definitely be interesting testing it with some steel shafts even without any fletching just as a proof of concept

[@Gazbeard]

If the shafts are tubular with threaded heads, you could also try an old armour piercing trick we used in the 1980s where you drop a few ball bearings or fishing lead shot into the shaft. When loaded on the bow ensure the weights are at the flights end of the arrow/bolt shaft - when the tip hits the target, the weights slam forward providing a second energy kick to the penetration. With the bodkin on that 3rd crossbow and weights in the shaft, I'm sure you'd have had a full penetration.

[@BuckScrotumn]

For anyone wondering about the front stabilizers for the Siege like me for the past 4 months, I finally saw them available on the go gun website and they’ll be shipping out late June.

[@Kargoneth]

That was amazing, Jörg. I did not expect such penetration depths. I was also worried about your hand getting cut by the three-pronged hunting tip while you were trying to pull it out of the plate and when you were trying to pull the plate out of the vest.

[@sevenproxies4255]

It's true. Military vests do cause back problems. Ironically the manufacturers of this modern kind of body armour have forgotten a lot of lessons which medieval armor smiths knew about. Like how to properly displace the weight of full plate armor unto the wearers body. Modern armor is mostly resting on the wearers shoulders only which is really bad for the wearer long term.

[@swirekster]

some ceramic plates are also stand-alone and they have kevlar backing, some have titanium skin preventing ceramic shards from falling off after being hit or being damaged by bumping it on the ground. i guess steel plates would be better than ceramics against the crossbows coz u dont have to deal with things like spalling, at least to not as such extend as bullets breaking apart on hit.

[@Arachnoid_of_the_underverse]

One also has to consider weight of the vest being warn during duty hours, steel is extremely heavy compared with kevlar and also less flexible.

[@FarmerFpv]

Most if not all Ceramic plates are alumina, boron carbide, silicon carbide, and titanium diboride. They don't shatter or shard even when stand alone. It's not like the ceramic plates used for dinner. US Navy seals and special forces have mostly Boron Carbide plates which is one of the strongest materials in the world next to diamonds. It's kinda stupid that our police officers don't have such protection as they need it nowadays. So many officers would be alive today if they issued it to them. It's crazy that the people we depend on are left practically naked compared to the criminals who use military-grade vests.

[@swirekster]

i was talking more about shards in sence of getting pieces lose and fall of after being hit not the shards as sharp fragments@@FarmerFpv

[@another3997]

​@@FarmerFpvHave you ever felt the weight of a rifle rated ceramic or a steel armour plate? They aren't light, but they are bulky and inflexible. They also only cover a small part of the upper body. Wearing such gear for long periods is going to be uncomfortable, especially if you're spending time inside a car every day. The extra protection is offset by a decrease in mobility and stamina, such that you could be MORE vulnerable than without it. The vast majority of weapon threats faced by police officers are from handguns and knives, and relativley lightweight soft armour is adequate and preferable. Officers in SWAT teams are likely to need the extra protection. No armour makes you invulnerable.

[@Master_Yoda1990]

​@@FarmerFpv I've seen ceramic armor plate being shot at and they do definitely break. Most can only take one shot before it becomes ineffective for the part of armor shot. Steel plate maybe a little heavier, but it offers way better protection.

Shame these are not ceramic plates, they are UHMWPE plates, ressined plastic. Ceramic plates would laugh at arrors, way too hard material for an arrow to do much.

[@another3997]

​@@shepardpolskaTechnically they are unidirectional, non woven fibres heated and compressed by high pressure to bond them together. They don't use a resin in the sense of traditional glass or carbon fibre composites.

[@AnthonyA1995]

I feel like in combat it's probably more a weight issue as far as protection goes these days - it's impractical to provide full body protection ala full-plate armour these days, hence why we only really protect the vital torso and brain regions with ballistic plates and helmets. While that definitely helps keep FATALITY rates lower, CASUALTY rates must still be decently high - a lot of injuries in modern war are caused by artillery, mortars etc which these only provide a little protection from, and even from regular rifle fire a bullet to the leg or arm is still going to be a sufficiently incapacitating wound to keep a soldier out of the fight for weeks or months at a time, if not indefinitely. It may not kill him, but it very well might render him temporarily or permanently combat-ineffective. I'd definitely still rather have a vest than not though. I imagine I'm likely not alone in saying I'd happily take wounded over dead any day.

I believe theres five different types of ceramics most common in army vest is Boron carbide and there not like tile ceramic, so im not surprised they hold up well againt any pointed object as thats what they are especially designed for.

I'm pretty sure here in the UK their armour is rated for protection against stabing and firearms, they are also more lightweight/thinner than what you have shown here, would be interesting to test one of those, or even just a dedicated stab vest

[@another3997]

There are a mixture of protection levels for UK police and PCSOs. Some are only rated as stab resistant, some are rated for both stab and ballistic protection. For "soft" armour, there are 2 government approved levels for each type. HG1/HG2 for handguns and KR1/KR2 for knives. Levels 1 is the lower of the two. They are roughly analogous to the US NIJ level 2 and 3A. Spike protection is a separate category, as is rifle round protection.

[@Slingshotchannel]

Actually, gunfights are extremely rare in Germany. The bigger risk for a police officer is knife stabbing - and the police issue vests offer ZERO protection against those.

[@Neruomir]

That's not a modern military ceramic plate, that is probably a Kevlar polyethylene composite plate. Far lighter and can handle more hits but can't generally stop AP rounds at all and is iffy ageist standard military rounds within effective range. Still better than a t-shirt and a prayer tho.

[@AnthonyA1995]

Yeah, the damage to the plate shown isn't what I'd expect of a ceramic plate. It's definitely cutting the plate more than shattering it, even if it was a segmented plate I'd still expect at least localized shattering instead of a more clean cut like what is shown, since the shattering is HOW ceramic plates dissipate the force. There's a reason most plates are only rated for a few shots for whatever calibre they're rated for, once the plate has been sufficiently shattered it loses a lot of it's protective ability. Still impressive to see how well it handles the power behind a crossbow bolt though. The material science behind those plates, ceramic or otherwise, is seriously impressive. That's an ENORMOUS amount of penetrating force being stopped dead in it's tracks. Even the ones from the full power single-shot two-handed reload crossbow barely poked through, those could easily make it through a decently thick metal sheet as shown in Joerg's other videos and even those only just got through - I doubt you'd get more than the wind knocked out of you and maybe a small cut from those penetrations.

I believe most modern police issue vests offer protection from knives. However, as Joerg once dramatically demonstrated, not all blades are the same, and some attackers are stronger than others. Practically speaking, you can't make someone invulnerable to every possible combination. Syringes and flechettes, stiletto knives, big, heavy spiked weapons like an ice axe or a pole axe, machetes, swords, arrows... they all provide different challenges to a typical knife.

[@Kargoneth]

@@another3997 Well said! Yes. It's all about trade-offs. You have to choose how much you want to protect against each type of damage, how many resources you are willing to spend to get that protection, and how many side-effects you are willing to endure to maintain that protection (reductions to mobility, flexibility, and heat dissipation; increased sweating, fatigue, noise, discomfort; etc).

[@Macieyevsky]

Now test this vest against AR 480 MKII crossbow. I think that it would make a difference. Maybe small, but when the tip penetrates the plate, then it should not require much more energy to go way deeper.

[@NoreasternBladez]

Armor plates are designed to stop ballistics based on its mass vs momentum against itself by spreading the impact across the plate rather than concentrating the energy I ward, breadheads have more weight pound for pound, with the added weight of the shaft itself. That's like throwing a rock 1,000 miles per hour at a wall, vs throwing a balista bolt at the wall at 100 miles per hours. Lastly, has there been a 1 inch hardened and tempered steel plate added, nothing would have gotten through.

[@Jmbr-eh6xr]

Crossbow bolts kill underwater, it is more or less the same as speargun, can punch straight through not only baliistic body armour but also bullet proof glass, scarily crossbows and bows still have a place in modern warfare, ideally as someone pointed out, body armour needs to have steel plates or some other material alike, in case someone uses crossbows against you

[@another3997]

They can punch through SOME armour or armoured glass. Just like certain bullets can penetrate SOME armour. You choose an armour that can provide limited protection from the most likely threats. I don't know of any military that issues crossbows as standard equipment, the same as they don't issue everyone with .50 calibre rifles with armour piercing rounds. However should any military find themselves fighting an army equipped with crossbows, I'm sure armourers would be tasked with finding suitable solutions.

Point of order: the penetration of “bullet proof” vests is not about the pointiness. An arrow or a knife has a lot more mass behind them. The vest can only take so much of an impact from the projectile before it spreads apart the fibers and penetrates.

Wieder ein spannendes Video👍🏻Vielen Dank und LG🍀

[@lordnai8260]

Bro love your videos, been praying for your last shed and I hope that things are recovering over there

[@Negodyay77]

Krasse Nummer, man kann sagen das Armbrüste eine bessere performance haben als Schusswaffen, in bestimmten Senarios. Leiser und effektiv gegen Schutzaustattung.

The italian soldiers joke was on point!

[@martinschnell860]

Dear Joerg, you've been fooled. This is neither an SK4 nor an NIJ Level IV plate. It's either SK3 or NIJ Level III or III+(III Special). That means it would stop 5.56 Nato and 7.62 Nato rounds with a lead core like the M193 or the M80 with ease. If it has a III+ or III Special rating for 7.62x39 it will also defeat the M43 round which contains a mild steel core. Please check the label on the back of that insert. As far as I can see, you have a lightweight polyethylene plate which should also float if you throw it into water. These are layers of PE joined together under heat and high pressure. These layers delaminate on impact to absorb the energy of the bullet. If you hit that plate with a coin it will sound like a tile. The colour of that plate looked a little bit like ivory... I guess it's an old material. If it feels a bit sticky, it could contain parafin also known as wax. An SK4 or NIJ Level IV plate would have that as a backingmaterial... on top of it you would have a ceramic in form of tiles or a monolith plate made of aluminum oxide or B4C to shatter an amour piercing penetrator or core from an SS109/M855 ,P80 or M2 AP on impact. So let me take that illusion from you... you will never penetrate an SK4 or NIJ Level IV plate with an arrow or bolt. But if you scale up you might have a chance... would love to see your spear bazooka again. Btw I am impressed you made it to a "stopped in vest". Anyway... if you wear that PE plate in conjunction with that vest it will feel like nothing when the arrow or bolt strikes it. It's like knocking on a door, just to say hello ;) If you are interested in ballistic or stab protection please check "www.vpam.eu" Under KDIW 2004 you'll find all the information about levels of protection against pointy stuff like K-Klinge(blade), D-Dorn(spike) and I-Injektionsnadel(injectionneedle) and protection against bluntforcetrauma W-Würfel(cube). Best Regards

Really surprising results. I honestly would not like to get shot with a cross bow. Great video.

Moin Joerg, um die ballistische Einlage der italienischen Weste einzuordnen. Ich hab nämlich die Platten als ausgemusterte Gebrauchtmodelle billig über egun erworben. Meine Exemplare sahen etwas runtergerockt aus, würden aber immer noch ihren Zweck erfüllen. Da bei meinen die Umhüllung fehlt, kann man schön den Aufbau erkennen. Dein getestetes Objekt dürfte kein Keramik sein (die wäre sonst gesplittert und hätte keine Einschnitte), sondern Kevlarfaserverbund Die Frontplatte ist ne ca. 1-1,5cm dicke Platte aus verklebtem Kevlargewebe, dann kommt ein ca. 1cm Hohlraum und dann eine dünne Platte aus Kevlar. Die Platten werden mit einem Schaumrand auf Abstand gehalten. Einerseits bremst der Schaumgummi die Einschlagsenergie wie ne Art Knautschzone und sorgt dafür, das Fragmente erstmal Weg überwinden müssen, bis sie die zweite Platte erreichen. Ähnlich wie die Zweikammerpanzerung in Weltraumfahrzeugen. Oder bei alten Rüstungen der gewölbte Dom der Brustplatte, etwas Luft und dann der Gambeson. Was durchschlägt muss erstmal den Anstand überwinden. Auch hat eine Einbeulung der Frontplatte mehr Abstand zum Körper des Trägers. Das sollte die Rückseitendeformation und stumpfes Trauma minimieren. Das ist sicherlich ingenös ausgeknobelt, das es ausreichend Schutz gegen Splitter und Pistolenkaliber hat und gleichzeitig nicht zu schwer ist. Ich vermute mal, gegen Gewehrkaliber ist es höchstens auf größere Distanz ausreichend. Aber, wie man sieht, genügend Schutzwirkung gegenüber Armbrustpfeile. Insofern ist die Platte nicht so massiv, wie sie daherkommt. Ich denke, dass ist spannend um die Pfeilwirkung einschätzen zu können. Ich bin aber ziemlich beeindruckt, wie heftig die Pfeile der Platte zugesetzt haben.

[@rashedusman9717]

It wasn't such a surprise that the plate stoped the arrows, but what about the rest of the vest where isn't any plate?

[@rcengineer8159]

My understanding is, usually plates, especially ceramics are meant to break an incoming projetile into fragments and thus enabling the cevlar to catch the fragments. I think for stab resistance ( what I reckon these bolts are more alike to) other materials that don't shatter are used.

[@charlesblaicher7589]

Glad to see you. Be well sir.

[@felype_fbborges3314]

You should use some blanks or any else explosive tip for bolts to make more damage into bullet proof vests.

[@snivanov]

JunXIng upped their models rescently and now we've got Doom Armageddon crossbow with 360lb draw weight and 31 cm power stroke and built-in pulley system with 1 to 3 mechanical advantate. I think that beast will completely penetrate this plate with extra heavy arrow and right arrowhead geometry

[@Feinwerks]

Maybe you shall assemble your hardened blowgun tip on the Hex 400 arrow and repeat this trial - By reduceing the impactarea, you shall increase the penetration massively.

[@ryanjohnston3229]

As someone with German heritage, i find your humor witty 🍻

[@christianbenda6489]

Echt beeindruckend, obwohl diese italienischen SK4 irgendwie suspekt aussehen 😅 die meisten sind in einer Art schwarzem Covermeterial eingeschweißt/umhüllt. Hätte mich echt noch interessiert, wie eine SK4-Stahlplatte gehalten hätte.

[@revisit8480]

Wenn sich die Orks in Warhammer 40k rot anmalen, dann liegt das an ihrem Glauben. Sie glauben mit roter Farbe wird man schneller. So ungefähr verhält sich das mit deinem Covermaterial, wa? xD Das Rüstzeug was du da siehst braucht kein Covermaterial, besonders weil die Platten wahrscheinlich so geliefert wurden mit dem Plattenträger. Von der Qualität her sollten diese sogar sehr hochwertig sein. Mit dem Ballast der da aufschlägt haben sie kaum Schaden genommen, und die Beulen, auf der Innenseite, sind kaum sichtbar - in diesem Fall wäre der Schütze sicher. Sie sind übrigens nicht aus Keramik - zumindest nicht das Obermaterial (kann sein, dass was dahinter, in einer dünnen Schicht, irgendwo enthalten ist) - meiner Meinung nach, wie schon gesagt, sind die hochwertiger als der Ersteindruck vermuten lässt.

[@BuckScrotumn]

Where do I get those stabilizers for the siege???

[@popuptarget7386]

Got to love the unexpected bit of a jab at our Italian friends. 😂 No worries guys, we love you but of course, we will be merciless in our teasing.

[@patrickshannon4854]

How are you progressing in your shop repair? I've enjoyed your content for a long time and hope you continue in the future.

[@Slingshotchannel]

The work has begun!

[@Hipporider]

Why not try a compound bow? Great video 🇦🇺

[@random-unbreaded-commentor]

I mean, you should've just said the vest you tested it on was a Russian police vest and I bet people would've been cheering. 😂 Glad to see you making content again my guy! Few KZbinrs I actually notice gaps in content and you're definitely one of them!

[@derstoffausdemderjoghurtis]

his Workshop burned down

[@cheekarp2180]

A door staff (bouncer) got killed a few years back, he was wearing a bullet proof vest but a knife went through it.

[@kenofken9458]

Standard ballistic vests are not rated for stab threats. They do sell ones that are.

[@craigsaunders7037]

I liked the Italian soldier joke. Even the Germans recognized their favoured tactic of retreat in WW2. LOL. Which reminds me, did you hear about the Italian tank, it had one forward gear and 4 reverse gears.🤣

[@TrickyDickyP]

LOL.. "protection on the back side"... nice one....😊

[@evgenibelchev4544]

I almost choked because of the Italian soldiers joke. Good one!
