Hey all,
I've just been asked if I might do some more carbon skinning. I'm only really interested if I can advance the process a little, it can be a touch hit and miss and represents quite a lot of effort so I'd like to learn something from it.
Anyway the main problem I have had in the past was adhesion / conformation of the skin to the surface. This is the biggie that I want to eliminate.
Using the skinning bascoat (black,fairly thick epoxy) works fairly well, but it can lift off if you don't keep an eye on it. And edges and sharp curves can be a real problem area. I usually leave excess around the edge and then tack that to the underside of the part, so it's very easy to get a little lift around the egdes and I end up checking every half hour until it's cured!
What I was thinking of doing was using a clear resin, so that if it bleeds through the cloth it won't affect the finish. I was then going to wait until it went tacky, lay the cloth and then cover with peel ply and place in a bag, then vacuum and hold until cured.
Any thoughts / suggestions?
Cheers
