Abstract

With the progresses of material sciences and technologies, carbon fiber composite shell-plate structures have been widely used in aerospace industry. Suffering from the drastic change of penetration thickness during the 360°scanning, conventional computed tomography (CT) is difficult to be applied to this kind of structures with a big length-width-thickness ratio, and not easy to implement the defect detection and the performance analysis. Based on the existing diffraction enhanced imaging (DEI) device at Beijing Synchrotron Radiation Facility beam-line 4W1A, a new computed laminography (CL) scanning system was designed and developed. It was integrated with the DEI device to form a synchrotron radiation DEI-CL system for plate-shell structures. Within this system, the components such as light source, detector and turntable and the working principle were discussed in detail. The experiment results of a decimeter-scale carbon fiber composite laminate sample validate the developed scanning system.
