I have done some small parts in CF and FG, even some skins. I have also done some searching on the internet and also on here as I am trying to make larger parts.  I am looking at making a full carbon fiber set of doors for my Audi. It will mostly be a daily driver. (I say mostly as I ride my motorcycle in the summer and truck in the winter.) I will also do weekend racing in the summer at the track.) I am looking for this to be light and still look good. If I can pull this off I will move to other body panels. But my question is this. Do you have to put a core material in between the layers of CF or will CF be enough? If you do, how to you factor where to put it? Lasty, what is the purpose of it? The car will be use for hauling kids around and things so I want to do it right but still be strong enough.

I made mine much stronger than the original doors, with a soric core and Kevlar etc... The doors weigh 6kgs bare or 9kgs with glass and electric windows etc.
