Try putting a thin coat of the thinnest CA (super glue) on the carbon where you want the cellulose cement to adhere. Make sure the carbon is clean. I recommend that the carbon surface is also roughed up with medium (brownish-red color) "Scotch Brite" or something similar before cleaning. After the CA has set, glue with Ambroid/Duco as usual.
This works because the cellulose cement adheres well to cured CA (the acetone softens the cured CA surface a very small amount) and the CA sticks to carbon (actually, the epoxy in the matrix).
This trick also works for gluing polyimide tubes to balsa (used in place of paper tubes).

I have tested the adhesive between balsa and carbon tubes. According to my tests duco or ambroid do not give adequate joint strenght. Also tested epoxy diluted with ethyl alcohol but weight of joint is significantly more than cellulose cement. Any advice?
