Ar500 steel plate can stop rifle bullets. In my brain I’m thinking like “well if kevlar is stronger than steel, then slab of kevlar of the same size of an ar500 plate should stop rifle bullets too”. Clearly it doesn’t and I don’t understand why
In: Engineering
an ant (pound for pound) is stronger than a human. I can crush an ant with my pinkie, but not a human. so being stronger in that sense doesn’t really mean anything.
a bullet from a rifle is travelling way faster than one fired from a handgun. You wouldn’t wear just a kevlar vest if you are expecting machine gun fire. In the military we wear a ceramic armor plate inside of a kevlar vest. I wouldn’t even want to wear a steel plate because that’s transferring the kinetic energy of a bullet strike straight into your chest whereas a ceramic plate is meant to crack and absorb energy.
Kevlar is great for things like law enforcement or personal protection details where mobility and/or concealment is critical. It does a good job at stopping rounds from a handgun, which you are most likely to encounter in those duties.
