I feel like it's a sorta kleenex/band-aid/tupperware thing where the actual item is called something different but its so associated with that one brand everyone just calls all items of that type the brand's name y'know?
Actually, the tires wouldn’t just serve the purpose of being bullet proof, but also last very long due to being made of the material. A tire might accumulate more damage than getting shot at over the course of many years, but your car will be fine because it’s not the thing touching the road.
I get the joke but even in the toughest all terrain tires the sidewall is still the weakest. (Meaning that even in the most military grade bullet resistant tires, the sidewall is never strong enough) Unless it's a semi truck tire that weighs hundreds of pounds then the tire can still be pierced. But once again it's only the sidewall. Only military semis/tractors are 100% bulletproof with rubber tires.
@@containedhurricane I remember watching an experiment about this, and the answer is yes. Although there might be a small cut, but you will be fine. However, if it is a long sewing needle, then you will get pierce pretty badly. The needle can pass the tiny gap between fibers pretty easily.
As someone who worked in private security before, i can attest that sometimes a Level III bulletproof vest is often a lifesaver. Not just to protect one self but guarantee that'll be home on the next day and so forth. Sure the weight can be cumbersome but after awile, you'll get use to it and yes, you eill sweat in them. I knew some cops who do wear them in some of my old post who come would say the same thing as it'll be uncomfortably weird in not having them on.
1:59, shouldn't it be terephthalic acid instead of that terefloral chloride (idk name), the cooh has an oh structure for condensation, without it polymerization itself shouldn't happen.....am I missing something,sorry new to this
I used to make bulletproof vests rated for 7.62 rounds. It starts with a ceramic plate, then hundreds of layers of super plastic are compressed by being superheated in a kiln around the plate. When it comes out you spread this extremely caustic epoxy around the edges of the finished product to protect it from environmental hazards. THEN the plate is stitched into a Kevlar vest. The whole thing with a front and back plate weighs about 15 lbs. We were also considering making helmets that could withstand pointblank 7.62 fmj's but ultimately decided that it was pointless as the force of impact would likely break the wearer's neck anyway. It was a good job but government contracts were unreliable, we'd spend entire weeks just sweeping floors during periods of stagnation. It was nice knowing that I helped craft a product that saved a few lives though.
Another interesting bit of history is that bullet proof vests existed before this point. I believe Jan Szczepanik and Casimir Zelgen worked together to invent one in 1897 primarily using silk, which had worked noticably well in protecting from the blackpowder guns of that time. There are anecdotal stories of people surviving gunshots due to silk handkerchiefs in their pockets! I don't know why silk worked so well, hopefully someday I can do a little digging and find out.
my guess is because it's stretchy like a trampoline so the bullets just bounce off but I could be completely wrong since I am not a silk expert (I also know Silk can be made by spiders and it has to be pretty strong for their webs so say for example a fly doesn't just break through it so that could be another factor)
Pretty cool to learn that a female chemist was the one who invented the polymer to allow for bullet proof gear and vehicles, air craft, etc. to be invented
As someone who is a retired police officer I have wore tons and tons bullet proof vest I sometimes got shot but it wasn’t that big when hearing that this guy made the vest I started thanking him for my life for days P.S i got shot for like 10 times and 8 of them come from facing mass shooters I still feel the pain today but at least I am not dead
Yeah, they made her look kinda Indian, and her head is so small in comparison to her arms. Sure, that could be the art style, but I agree with your point.
Bullet resistant vests are good against small calibres and from assault rifles especially when they being fired at from a good distance away and the bullets lose energy, But if you get hit by a 50 cal. Nah you’re done for.
Why not go further? A 120mm tank shell won't be stopped either... LOL. Of course if the bullet (projectile) gets bigger and its charge gets stronger, the vest will have a harder time stopping it...
Theodore Roosevelt: A bullet can’t stop the bull moose! Ben: Ohh, he a zombie! Headshot! James: Why did you do that man? You tried to do assassin’s creed call of duty stuff. He got a vest.
If the purpose of a company is to produce shareholder value some way or another, then probably yes. If the purpose of the company is to provide the best product or service it can to the world, probably not.
I mean they used plate armor in the Napoleonic era and theres a famous cowboy heist involving a cast iron stove being turned into a walking suit of armor so not really sure what you mean
@@jazarli1825 theres nothing to talk about. Technology changes over the years. Also not going to mention that kevlar wont protect you against a 8mm mauser or 30.06 without high end plates which isn't just kevlar anymore but combinations of different materials. They had steel body armor which would have stopped these rounds but was heavy
0:58 Why do these videos always use that same corporate artstyle? Like why would an artist look at a picture of her, and decide to draw her arms massive, her head tiny, and her skin a different color?
Average hunting rifles will shoot through the chest plate, front, and back of at least one Kevlar vest, the one I had anyways. I had nothing long enough to measure how far the bullet penetrated into the live tree that we strapped the vest to. I wondered what kind of injury one would suffer if there was enough Kevlar to stop that bullet.
padded jacks of history could resist firearms back in the day at long range, some accounts of the spanish using incan cloth armour due to it being not way too far off from their cuirasses but way more comfortable

This is why Frank Castle aka The Punisher loves wearing bulletproof armor sleeveless undershirt singlet jacket because he always wants this for preparation protective purpose.
Very important note: Kevlar is a brandname owned by DuPont. The actual material is Aramid.
I feel like it's a sorta kleenex/band-aid/tupperware thing where the actual item is called something different but its so associated with that one brand everyone just calls all items of that type the brand's name y'know?
All Kevlar is an Aramid, but not all Aramids are Kevlar.

“My tires were bulletproof, but unfortunately the rest of my car was not”

While not rated for blades, kevlar vests are pretty darn resistant to blades.
Read this as “while not rated for babies”
So, bulletproof kevlar vests can prevent a knife from piercing our body?
@@containedhurricane The knife will most likely make it through to your body, but only the tip. Still, it'll ruin your armor.
@@containedhurricane I remember watching an experiment about this, and the answer is yes. Although there might be a small cut, but you will be fine.
However, if it is a long sewing needle, then you will get pierce pretty badly. The needle can pass the tiny gap between fibers pretty easily.
@@containedhurricane It will work wonderfully against slashes, but thrusts and piercings being stopped will depend on how thick the vest is.

Compliment for the job, few can say I've created modern armour which saves lifes
Kevlar is also used as snare drumheads in modern marching drumcorps due to the very high tensions required. They produce a crisp and articulate sound.
I thought it was simple, but now I see that it’s fascinating 😆
1:57. She didn’t make kevlar. She made aramid. The fabric is called aramid while kevlar is the brand name that made the first aramid
it's about as pointless to say this than to say the same thing about chap-stick, jet skis or escalators.

This was very educational. I never knew the material was so complex!
I feel like the caricature of Stephanie Kwolek (1:00) underestimated her big brain and overestimates her body size a little 😂
Nah its the style of caricature See 0:27 everyone is the same type.
@@anuragsharma4159 it's so bad though
1:35 Stephanie’s body-to-head ratio is crazzzyyyyyy. Anyway, I love the video 😁
Gotta love how they made Stephanie Kwolek ambiguously brown here when is real life she was very much white
Really good and diverse subjects to learn about through these informative and attention seeking videos.

This comment is an obvious lie. Shot 10 times, and 8 times from mass shooters? Jesus. No need to lie over the internet. Your channel is a kid as well.
Thanks
Was not expecting Ted-Ed to make something related to the military, I'm glad they did.
And its important to remember bullet resistant doesnt mean stab or slash resistant. So knives are still dangerous.
it does: bullets are essentially smalle blades/pointy metal bits traveling very fast
@@slkjvlkfsvnlsdfhgdght5447 I'm going give others a chance to correct you before I jump in.
@@slkjvlkfsvnlsdfhgdght5447 I hope you're trolling

Lol, I was thinking the same thing. She has huge arms and such a tiny head. 🤣
Maybe that’s just the art style.

@@vincentlee7359 While not conventional, you could carry with a 500 S&W or desert eagle. Definitely not expected, but it's a choice.
@@setcheck67 who has the money for that 🤔
I wish my high school chemistry teacher had taught like this🙂↔️
Neat.
Very interesting but the odd human body shapes used in the illustrations were distracting.
I wear Kevlar pants when I ride my motorcycle. Teamed with an armored jacket and a well fitting helmet, I have a better chance of surviving a crash.
yupiiiii new video ;))))
anything that can either absorb or organize shock waves from bullet's impact can be used as bullet proof
1:15 I like her tiny head and big arms. There needs to be more character designs like this. She reminds me of the dude from big hero six! 😄
All polymers with sufficient number of repeating units, have a viscous behavior that's why they are called Visco-Elastic materials.

Taking notes...
The caricatures are unsettling.
Did the demon who created Jovia Financial's corporate identity animate this (IYKYK)? This graphical style is so.....unsettling.
very tricky - title sound super dangerous and exciting, but is talk about chemistry of micro fibrers. Very tricky :)
