I can 3D mill the foam core, has anyone tried carbon skinning in an application that requires some strength? Would I be best doing it under a vacuum? Could I infuse? How would I ensure a cosmetic finish (I guess at the very least it'll need flatting back plus lacquer) Any experiences/tips would be great to hear! Edited 9 Years Ago by jamesw

You haven't mentioned how big the part is so any advice will be purely just general ideas and advice. i.e. It's a big of an exaggeration but if it's an aerofoil for a hydroplane 4m long and 1m deep then the advice will be completely different than if you are making a 200mmx50mm radio controlled plane wing. In fact, you may want to look at how model plane foils are built, they use a mylar wrap sometimes to provide good compression and a smooth surface, then bag it up I've seen sailboat rudders made using a 2 part mould, laid up and cured separately then the moulds are joined and 2 part foam poured into the void.
