Consider the possibility that the epoxy may crack under multiple pressure cycles. The aluminum parts may have more yield than the epoxy/fiber parts. Clean and treat the metal parts carefully where the epoxy/fiber bonds to it. I'd take one unit to multiple cycles and see where failure occurs (if it happens). Consider this a 'fatigue life' on the second unit. Why glass filled? You trying to save mass? ;-> Wouldn't the unfilled stuff be stronger?

If you are ever bridging much of a gap or making a filet, you need to add some kind of fibers to epoxy. We use cotton flox for most things, as it is nice and easy to work with, but chopped glass fiber is stronger. Chopped carbon fibers are even stronger, but you shouldn't use carbon fibers in contact with aluminum, because you get galvanic corrosion.
