What's the Difference Between Kevlar® and Carbon Fiber?

Kevlar fiber has a tensile strength comparable with that of carbon fiber, a modulus between those of glass and carbon fibers and lower density than both. Kevlar aramid is used for high-performance composite applications where lightweight, high strength and stiffness, damage resistance, and resistance to fatigue and stress rupture are important.
