Hello,

I want to assemble à Wing (hydrofoil) onto a 1 inch carbon tube. I wanted to wrapp an aluminium plate with carbon fiber around the tube so to be able to drill and bolt into the aluminium.

I see there can be some galvanic corrosion. What should i do to isolate the aluminium? Would a simple coat of resin be enough ? Is there some minimum thickness ?

These could be out at sea... And although the AL is going to be into the part, the bolts (stainles steel) are going to be into the Al...

Is there the same problem with brass ?

regards

Thanks for the videos and all of the site. It is very "pro".

As already mentioned, a thin layer of glass is commonly used to insulate the carbon and aluminium for this purpose.

Insulating between two dissimilar metals is another issue.
