ABSTRACT:
A filled epoxy tubesheet comprises an epoxy filled with a metal, such as aluminum flakes. Embodiments of the filled epoxy tubesheets can bend due to stress on the surface rather than crack. Embodiments of the filled epoxy tubesheet can be used to improve Air Separation Module performance by reducing or eliminating leakage through crack in the tubesheet.
