What exactly do you mean?Its better to roughen up the ali surface with sand paper or other abrasives at least 240grit. Then clean with acetone and bond within a few hours.By etching I mean using chromic acid to roughen the surface a bitSanding would be easier and faster imo, Degrease first with acetone or degreaser, use fresh cloth after cleaning everytime till you dont see any more residue on your cloth, that way you are sure no grease or silicone or whatever is left on your plate THEN start sanding, otherwise you will fill the scratches with grease if it hasn't been cleaned before. then degrease and clean again. I would go for a 80 grit to leave some scratches and to be fully sure take a knife and raster is with the knife for more mechanical bond. Is sanding enough?Is it used for making the surface rough or roving the oxide layers primarily...Also I'm using epoxy resin and hardener as adhesive...Thank youdidnt know it was cf tube on a plate I would sand and clean the surface that will be bonded on the carbonfiber tube and the plate, but you can do whatever you want it's just how I would do it. why dont you use a glue dedicated to these types of projects? Easycomposites has a wide range of 2K adhesives for bonding CF to CF or to plastics and metals Is sanding enough to make the aluminium surface rough?
