I work for Lotus cars, bonding glass- and carbon-firbe parts. We use something very similar to JB Weld (Betamate, made by Dow, don't know if it's available retail) for some of our parts, including metal-to-composite bonds. Bonding epoxy would be good too (not the same as laminating epoxy), as long as it's resonably thick (like JB Weld).
The real secret is prep. To apply the glue to a front crash structure for a Lotus takes about 5 minutes, but the prep takes 25 minutes. Make sure everything is keyed with Scotchbrite (or steel wool), cleaned well with acetone, and preferably primed with an appropriate primer (ask your epoxy supplier).
