Autofratage Composite Design

This project wil address the design and manufacture of a composite overwrapped tank with a thin metal liner, compatible with the requirements for containment of ultra-high purity gases. The complete tank design will be subjected to a Finite Element Analysis to provide a tank which will operate safely within the prescribed pressure limits of 200 bar (3000 psi) working pressure and 600 bar (9000 psi) proof pressure. The linear portion of the program will be to design a liner than can be manufactured with the fewest possible areas for entrapment of contaminants, with primary consideration being given to optimizing the approach used to manufacture the Demaray tank liner. Composite winding and curing parameters and liner pressurization procedure will be developed to provide the desired results from the autofratage process. Process methods will be developed and documented in manufacturing process plans. A study will be performed to identify candidate materials for the filament wound overwrap and the high impact outer cover for the overwrapped tank. Provisions for stacking and handling will be considered during outer cover design, with the target of integrating the cover and handling/stacking features.
