Abstract Scope |
The AFRL/RXNP and NASA Single-Case Study Program pushed Air Force X-ray nano CT capabilities to investigate three-dimensional spatial damage evolution of a composite microstructure undergoing slope instabilities. The RX Materials Characterization Facility is responsible for the development of the state-of-the art load frame technology specifically designed for microscale testing via in situ scanning electron microscopy and in situ X-ray nano CT characterization. AFRL/RXNP developed a method to perform 4D X-ray nano-CT experimentation by reducing the number of projections needed to acquire a viable spatial 3D images. The experiment illustrated that fiber/matrix debonds were the dominant failure mechanism. These experimental studies enable the exploration of composites materials under complex stress states and how the distribution of fibers can ultimately affect the performance. Understanding slope instabilities will improve multiscale characterization paradigms that enhance interlaminar fracture properties of Air Force relevant composite systems. |
