X-Ray Computed Tomography for Advanced Materials and Processes.
Abstract
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 the payback will be greater for data leading to faster decision making or improvement in the product. The development and qualification of new materials, joining and manufacturing processes for advanced aircraft/aerospace applications is accelerated by the availability of quantifiable data on design characteristics and their variations. X-ray computed tomography (CT) provides quantitative measurements of material characteristics in terms of the dimensions, density and composition. The sensitivity of CT is dependent upon a number of factors including the test article and the CT system technology employed. The evaluation capability of CT overcomes the limitation o current qualitative inspection techniques to provide an objective measure of material or component condition. The results of studies involving CT testing of various advanced materials, manufacturing processes and joining methods revealed four specific areas in which there is potential for significant economic benefit from CT. These areas are new product development, process control, noninvasive micrography, and material performance prediction....
