aluminium plate is not adhering to a carbon fiber laminate.Is it because my aluminium surface is too smooth?
I tried etching process to make it rough.But It did not work out well.Is sanding a better option than etching?

+xaluminium plate is not adhering to a carbon fiber laminate.Is it because my aluminium surface is too smooth? I tried etching process to make it rough.But It did not work out well.Is sanding a better option than etching? When you say etch? 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 bit

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 it used for making the surface rough or roving the oxide layers primarily... Also I'm using epoxy resin and hardener as adhesive... Thank you

Thank you didnt 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?

Sanding will be fine
80grits perfect,just blow down,decrease an bond
If you really want a good bond drill a couple of holes an rivet the part on as you glue it
