The layup is 8 layers of carbon twil and one relativly heavy layer of kevlar, epoxy is the matrix.

edit: I'll be testing this one over the next few weeks the might make some improvements, probably going a little thicker in the layup, possibly some uni's.

While the fabric will retain the strength, the resin will not retain the structure/form, it'll be tethered well, but flap around.
Carbon actually has better resistance to crack propagation than aluminium, each strand acts as a barrier to the crack.

Yes, I agree that was my point, if it does fail the kevlar keeps the pieces together. Not the best option but it does keep everything together.

Like I said before I've been running a cf tower for more than a year now and have had some quite big crashes, the tower held up very well.

I'll post some photo's of the rest of the setup later this afternoon. I'm using aluminium for the sideplates, they can bend and absorb the impact/energy, the idea of the CF base is to have it as stiff and strong as possible.

Cheers guys.
