What's the best Body Armor materials?

Question

There are so many materials regarding body armors. From the Kevlar®, Twaron®, Goldflex®, Dyneema® to Spectra®, Zylon®, Evoflex® and so on.
I've done some research and due to the aging and environment-weak properties, I can only rule out Zylon®.
Take this note, I've budget that covers the price of any of these and I know that materials play a simply lower role than the design and ballistic protection level but when dealing with the best, which? I heard that GoldFlex® is the best among all.
What do you guys think?

Answer 1

Depends what you plan on doing with it. All of these are soft "fabrics", so while they can stop low cal rounds, they're all pretty useless against rifles, and the new +P+ 9mm rounds have also been shown to penetrate these. Another side effect is that since the bullet is harder than these, it will be the armour and therefore you absorbing the energy, whereas ceramic plates (which I'd recommend) will result in the bullet absorbing the bulk of the energy. If I had to choose one of these, I'd also say GoldFlex, but I'd seriously recommend looking into ceramics, particularly dragonskin armour. Ceramic plates can now be made thin enough to function in covert armour systems aswell as military overt ones.



Hope this helps
