This program is to provide fatigue data on a graphite-epoxy composite. AS3501-5A was selected as the test material. Unidirectional composites with 0 and 90 degree ply orientations were tested. Both static and fatigue strength were measured. Multidirectional laminates with or - 45 and 0290 or - 45 ply orientations were also tested. The fatigue data were analyzed using Weibull parameters. The frequency of testing was kept low in order to limit the temperature use below 5 C. More extensive data will be generated and analyzed under this contract. Author
