Descrição
This novel Kevlar fiber is stronger, meaning that its makers hope they can fashion body armor out of it that's thinner and lighter.

Graphene-based armor could stop bullets by becoming harder than diamonds - “scientists have determined that two layers of stacked graphene can harden to a diamond-like consistency upon impact” : r/technology

Survival of the Fitted

Researchers 3D Print bulletproof plastic layered material that can withstand a bullet fired at 5.8 kilometers per second with just some damage to its second layer, which could be perfect for space
