What sort of layering would you suggest for using coloured carbon cloth to make car body panels? I am looking at making a carbon engine lid (resin infused process) for my '73 Beetle, for road use. Since the coloured cloth is a carbon/polyester blend and so has less strength that plain carbon I assume it needs a secondary layer behind it? I was thinking of 1x 210g Colour cloth, 1x regular 200g carbon, a 2mm Soric core layer, and then another plain carbon inner 200g layer for the inner, plus extra strengthening around the outer edges (seal, hinge & latch positions) and numberplate light mounting area. Would this be strong enough? I think this would make it about 2.75mm thick. Would this be a good strength for a road car? Or would you recommend a 3mm core or more carbon layers?
