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?
