A metal matrix composite (MMC) filament winding technology has been developed to meet the needs of advanced, high temperature composites applications. This paper summarizes the results of 4-inch diameter MMC cylinders tested in tension, torsion, and internal pressure (hydrostatic burst). The results showed a generally linear lamina response in longitudinal tension and a significantly non-linear lamina response in transverse tension and shear. The hydrostatic burst tests resulted in a translation efficiency of up to 80% in uniaxial testing of hoop-only cylinders, and 60% in biaxial testing of cylinders made with both hoop and helical plies. Improvements to the incoming fiber tows and processing modifications will be pursued to raise these translation efficiencies. This testing will lead to the development and refinement of predictive models that can be used for designing MMC pressure vessels and storage tanks.
