Hi,
    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.

Thanks in Advance

Hi, doors are not the easiest of panels to do. You will have to take moulds from your existing doors of the outer and inner skins. Also you will have to build in hard points for mounting hinges, lock mechanisms etc.
Core materials are really just a way of separating the layers of CF. In basic terms the greater the distance (thicker the core ) between the layers the stiffer/stronger the panel will be. This is because the fibres have to stretch further for a given deflection.
Typical lay-up for the outer skin would be 2 layers CF - 3mm Soric - Kevlar/Aramid ( to give some pierce protection and reduce splintering if the worst happens ) - E Glass. If the panel is fairly flat you could use Closed Cell Foam in place of the Soric. This would result in a slightly lighter panel as the resin up-take is less but it doesn't conform to curves like Soric.


Hope that helps and good luck with the project. Warren
