Due to demanding requirements imposed on current and future high-performance aerospace structures, advanced materials are being developed for and used in a variety of aircraft/aerospace applications. Production costs for advanced materials are generally higher and therefore the payback for data leading to faster decision making or improvements in the product are greater than for traditional materials with well established production methods. The development and qualification of these new materials would be accelerated by the availability of an evaluation technology that provides quantifiable data on design characteristics and their variations. X-ray computed tomography (CT) is a nondestructive evaluation methodology that provides quantitative measures of dimensions, material density and composition. The results of studies involving CT testing of various advanced materials, including ceramics, metal matrix composites and organic composites, reveal four specific areas in which there is potential for significant economic benefit from CT. These areas are: new product development, process control, non-invasive micrography, and material characterization for performance prediction.
