Study Of Urethane Double-Coated Nylon Membranes For Fluid-Storage Applications, Micah Austin Howell

Masters Theses

Polymer-coated fabrics are used for many fuel and water storage applications, such as in U.S. military field operations. Urethane-double-coated nylon (UDCN) is one such material used in collapsible fluid storage tanks. Research into the mechanical properties of UDCN membranes under different environmental conditions is necessary for substantiating its current operations as well as developing new technologies. Novel modular, closed-loop and scalable pumped-storage hydropower (PSH) systems are one technology that could use UDCN membrane tanks in order to mitigate large costs, risks, environmental impacts, and time-for deployment associated with PSH system construction due to their modular, closed-loop technology. This study focuses …
