The subject of this program was structural evaluation of high strain fiber and resin composite material systems. The objective was to develop a combined analytical and experimental procedure for performing a structural evaluation, then use it to evaluate the effects of recently developed higher strain fibers and resin systems on strength, durability, and damage tolerance of advanced carbonepoxy composite material systems. Testing included evaluation of basic lamina properties, static and fatigue testing of laminates with and without stress concentrations, evaluation of tolerance to low energy impact damage, and static and fatigue testing of a multifastener metal-to-composite splice joint. Included in the structural evaluation were analytical methods to predict unnotched and notched laminate strength and mode of failure based on unidirectional ply mechanical properties.
