    Abstract

    A composite materials data bank system has been developed to store large amounts of test data. At present, extensive test data have been stored for A-S/3501 graphite/epoxy, 5.6 boron/6061 aluminum, and HT-S/710 graphite/polyimide. The data bank is an interactive computer software with cost-effective capabilities for performing a variety of analyses, including prediction intervals, confidence intervals, design allowables, and Weibull allowables. Printer plots are available for presenting raw test data or a variety of analytical results, including superimposed results, on a computer terminal for quick reference.
