I know my epoxies. Trust me, 5 minute epoxy is not the same as this stuff. The world of thermosetting plastics (epoxy) is incredibly varied as each different variant possesses different properties. There is the general purpose epoxies that you buy at the store, then there's the ultra high strength environmental stress resistant epoxy that they use when they put the leading edge of the wing on a Boeing 777, there's epoxies that they use in space, there's also epoxies that are used in the jewelry field (my field) that we use to cast with, and epoxies in the CAD field that are laser cured and solvent resistant. I've got a whole paper on the stuff somewhere but trust me, if you tried to bond carbon fiber together at the recommended 6 sheets with all purpose epoxy, the results would be disastrous, regardless of its cure time!
