Hello!
I am planning to make carbon fiber + nomex honey comb sandwich sheets, about 1.5 m2 pieces. The sheets are not 100% straight, but no radical shapes neither included
The skins would be app 220g/m2 carbon, and inside 4,8mm Nomex, 5mm thick. What are my possibilities?
I red about dipping the honeycomb in epoxy. Also about the adhesive films etc. Even some sources say, that I can do everything in one pass, without glues (when using prepreg).....
Only the surface facing to the mold has to be perfect, other side does not matter at all.

Thanks for replies!
Would this make sense:
Making the first skin by resin infusion, with peel ply. After curing adding an adhesive film on the cured skin, followed by honeycomb, and on top of that a Prepreg (for instance
mtm 28 ) and then vacuumbagging the whole thing and curing in the oven?
