Gluing Carbon fiber

[PBO]

You want a 6mm laminated sheet? That's going to be incredibly stiff

I work with CF & a basic few tips;
-you want an epoxy glue with 60min curing time
-the faster curing time, the more brittle the resin will be
-you should allow the sheets to cure in 20-25 (celcius) ambient temp
-give the faces to be glued a good scratch with say 120p paper
-mix the resin & let it sit for a few minutes before you pour it out
-spread it out evenly with a plastic spatula
-put a little weight on the sheets once glued to ensure the top sheet has even pressure which will encourage the resin into the scratched surface

You need very little resin to make a very strong lamination & too much between the sheets will allow delamination to occur in a crash (for example)

In contrast to the advice panda was given, I wouldn't accelerate the cure with heat...heat is normally used in pre-preg not resin gluing, heat with resin can cause exotherms & you don't want that
