Darryn:
Can I ask what kind of glue and surface processing you use to make that combination stick together? It would also be good to know how you deal with electrolysis if you use carbon.
I know that you need special glue films and autoclaving, or great amounts of epoxy-filler to make alu-honeycomb stick to glass.
I got a tip some time ago, to sand the alu with 80grit sandpaper and apply the epoxy immediately before oxydation starts. Is this what you are doing?
Using 2024-O aluminium, roughed up with sandpaper, cleaned with MEK, West System epoxy,600Gsm woven Carbon, keep it warm with a light bulb, the aluminium helps here once again.
I only vacuum bag when I've finished prototyping, my prototypes usually get tested to destruction unless I cant destroy it when I overload it to a degree that I am satisfied with, then it may become the finished product.
I use this process for fairings/brackets, I dont deal with electrolysis apart from sealing the item well and inspecting regularly, so far I haven't had corrosion issues. My plan is to use well bonded conductive foil in the laminate, similar to what is used in aircraft fairings to dissipate static electricity build up if it becomes an issue.
