Hi Guys, first time playing with CF.
I am a designer and 3d printing enthusiast.
Im going to have a crack skinning the inside of these prototype velocity stacks that are going to live on a sprint car.
Obviously this is a fiddly curvature, I was thinking for layup I should approach it in 3 or 4 pie sections with the 2x2 twill I've got here.
I was just assuming any less than 3 fabric sections per layer and it would start trashing the weave etc.
Thoughts? (just one stack at a time not as a whole)
2" base dia 4.5" across the top.
Thanks in advance for any replies !

The first piece should be folded to the side, that you can place the last piece under it, and than fold it back. So every piece is positioned mould wise with the clear cutted edge, and the other side...
