In the frame of nondestructive inspection, computed tomography (CT) is a reliable and effective method for three-dimensional examination of the internal structure of objects. However, the inspection of flat components by means of CT has its limits and is turning out to be difficult due to restrictions by impossible but indispensable irradiation directions. In these cases computed laminography (CL) is a time-saving and cost-effective alternative. At this year's JEC WORLD Composites Show & Conferences, held from 8 to 10 march in Paris, France, Fraunhofer IZFP will present CLARA®, a fully featured CL machine for "nondestructive inspection of CFRP components using computed laminography" which was developed by engineers and researchers of this Saarland Institute. The results of the measurements and a complete volume reconstruction of the object are available within minutes.

In lightweight construction or in aviation application of fiber-reinforced plastics (FRP) is steadily rising. FRP components are often used in form of very large or flat shapes, which can be examined using the Fraunhofer IZFP’s CL device CLARA® (Computer Laminography and radiography system). As nondestructive inspection of complex components and materials is increasingly required along the entire material cycle but especially during the production process, the development of new, time-saving and cost-effective testing methods is essential. CT as a widespread X-ray method can obtain high-resolution 3D volume images to depict the finest structures and details. But considering in particular objects, where CT is unsuitable, CL is an efficient and effective alternative. "While in medicine CL is widely used, industrial applications are seldom to found despite some outstanding advantages compared to CT", Dr. Michael Maisl explains, senior scientist and group manager of the “Reconstruction, Image Processing, CT/CL by X-ray" group at Fraunhofer IZFP. Unlike CT, CL is perfectly suited for highresolution inspection of large or planar components. Compared to CT, the inspection time can be significantly reduced. Additionally, a variety of different recording shapes is available, which also enable adjustments to perform fully automated batch inspection. Similar to CT, radiographs are taken from different angles to compute a threedimensional representation of the object’s internal structure using a reconstruction algorithm.
