Within recent years, the need for new, cost-effective, function-oriented, highly integrated, and light-weight components has strongly grown in many high-tech industries such as aerospace, automotive, marine, and construction. The drivers behind this trend are mainly found in the rising application demands regarding efficiency, safety, environment, and comfort. Among desired functional and -mechanical properties, the requirements on new materials and components include high strength, elasticity, durability, energy efficiency, and light weight. Unlike conventional materials such as aluminum, steel, or alloys, fiber-reinforced polymers (FRPs) – composites made of a polymer matrix reinforced with carbon, glass, or other type of fibers – fulfill these requirements to a high extent. To design new materials and components, detailed investigations and characterizations of FRP materials are vital. In industrial settings, FRP components and materials are nondestructively tested, e.g., by visual inspection, tapping, or ultrasonic inspection. However, conventional methods are increasingly facing their limits regarding accuracy, level-of-detail, and inspection time. To overcome these limitations, industrial 3D X-ray computed tomography (XCT) has received much attention in quality control due to its high spatial resolution and ability to precisely capture external and internal structures in one scan. Compared to other non-destructive testing methods for FRPs, XCT is yet the only method capable of delivering full 3D information for detailed inspection and quality control.
