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
3/8 steel weights about 15lbs per sqft.
Typical person has about 10 sqft of coverage on their torso so we’re talking about a 150lbs of plate to cover the chest/back.
A similar kevlar vest weights 5lbs, plus about 10lbs of sacrificial ceramic plates
The plates are providing most of the protection by dispersing the impact on your body from the size of a bullet up to the size of a baseball. Still hurts, but it’s the difference between getting hit with a club and a club with a nail in it.
