Explore the chemistry behind what makes kevlar so strong, and how this essential synthetic fiber was invented. -- By 1975, Richard Davis had been shot at close range 192 times. But not only was he completely healthy, each of those bullets were part of a demonstration to sell his new product: the bulletproof vest. So, how does such a light, flexible piece of clothing stop a bullet The secret was a synthetic fiber material invented a decade earlier. Max G. Levy explores the incredible strength of kevlar.

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.

Well, good news w/the pew pew restrictions put on law abiding citizens not stopping school shtings, the libs are now going after protective devices like body armor to stop school shtings.
BTW, I'm not a trumper. I'm in the middle watching the two extremes sht on this nation.

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.

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 stsrted thanking him for my life for days

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.

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.

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

Is the future full plate cyber knights, or skin tight 50. cal rated jumpsuits
(A 50. cal would still kill you, but atleast your body will be intact)

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.

Kind of interesting we invented nuclear bomb before bullet proof vest. You'd think bullet proof vest will be really useful in ww2

I feel like the caricature of Stephanie Kwolek (1: 00) underestimated her big brain and overestimates her body size a little
