Bottom bracket Shell

Will be wrapped in pre-preg UD CF. Want to make sure the bond between the titanium and CF is stronger than the just the pre-preg resin. So which epoxy to use?

Tube joining

Tubes will be mitred and then fit flush to each other. Once they have been glued I will then be wrapped further pre-preg UD CF around the joints, so the epoxy needs to be generally strong with a little flex, however will not be the only structural element taking force and load.

I was looking at the ET515 Epoxy Adhesive, but I am not sure if this is the most suitable?

If not what would you suggest?

Joint filleting

Prior to wrapping the joints in further UD CF I need to fillet the joint so there are no sharp acute angles which could create a void after wrapping and curing.
