Abstract:

This report summarizes progress on fatigue crack growth through unidirectional SCS-6titanium alloy composites and the fatigue and fracture of ceramic matrix composites reinforced with continuous fibers, both large and small, in unidirectional and woven forms. The fibermatrix interaction is detailed for SCS-6titanium alloy composites near stress concentrations, and it is shown how that is similar to measurements of fiber stress in the wake of fatigue cracks. The main theme of the work on ceramic matrix composites is the effect of fiber architecture on fatigue behavior.
