lb for lb, its stronger than steel. It's also hella-light.
Anything that holds hydrogen under pressure is made of it, because if it blows, CF doesnt send shrapnel everywhere like steel does; it just splits.
People also like it for it's weave look. I personaly don't like plain patterns, I like twill weaves that give off a kind of 3D look. They come in many styles and weave patterns, and also colours. Kevlar can also be added for extra durability and/or colour.
Either ya like it for it's superiour statistics over steel, or you like it for looks. Or both!
It's the wonder fabric of the futur!
