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
Each fiber may be stronger than steel, but the fabric they make up is not as puncture resistant. This is also why some kevlar struggles with stopping knives.
Rifle rated vests use ceramic plates (or steel, but ceramic is better) to deal with this problem.
Steel is cheaper than ceramic, which is why you see AR500 used for civilian market rifle armor.
