That type of carbon is called 'veil' and it's non-woven, like felt. Normally used for an appearance layer. What you're seeing is wrinkles because it doesn't pull smoothly over irregular (curvy) areas as well as weave. The crown is often aluminum; so what they've done is cover it with veil instead of 'artfully' transitioning from black paint to carbon weave. Personally I like the veil better.
