Abstract : The objective of this study was to select and characterize the most efficient discontinuous fiberglass-epoxy resin composite for ultimate use in ballistically tolerant flight control components. Selection of composite constituents, ballistic damage and crack propagation study, and design allowable properties evaluation study are reported. The effects of various constituent parameters on the extent of damage and residual tensile load capacity were determined on standard specimens after tumbled caliber 0.30 ball M2 projectile impacts at 0-degree obliquity and 1800 ft/sec. Determination of ballistic test and composite variables on extent of damage and residual load capacity is presented. (Author, modified-PL)
