Clutch material questions

While looking for a clutch online I found several different materials they used to make them that I was unfamilar with as far as clutch performances, strenths, weaknesses, etc. I tried a few internet searches but everything kind of conflicted what other websites said.

Is anyone familiar with Kevlar, Carbon, and a composite of the two? I felt like any of the ceramic clutchs for the cobra were overkill and I don't need something that grabby for street/highway driving.

I ended up getting a Spec stage 2+ Kevlar/Carbon Composite that is still more than I need but found mostly good reviews on it. Most of the negative ones were about 10 years old or people slammed the kit because of a made in china bearing they included.

Well kevlar is heat reasistant and they also use it for bullet-proof vests.

Not sure about the Carbon

We've got Kevlar in 2 of our tractors, and I'm really happy with them! They'll squak a bit if they get slipped much, but they're WAAAAAAAAAY better than a ceramic clutch EVER thought of being!!
