![]() Within this study, different NDT methods will be compared at CFRP samples with specified artificial impact damages. One main advantage of this μ-XCT system is its high resolution with 3-dimensional analysis and visualization opportunities, which enables to gain important quantitative information for composite part design and stress analysis. It is an open system which allows different kinds of acquisition, reconstruction, and data evaluation. In addition to these techniques, Airbus Group Innovations operates a micro x-ray computed tomography (μ-XCT)more » system, which was developed for CFRP characterization. However, their quantitative information is often limited on impact localization and size. The advantage of these testing methods is the applicability on large areas. Non-destructive testing (NDT) methods for quantitative defect analysis of damages are liquid- or air-coupled ultrasonic testing (UT), phased array ultrasonic techniques, and active thermography (IR). Kiefel, Denis, E-mail: E-mail: Stoessel, Rainer, E-mail: E-mail: Grosse, Christian, E-mail: recent years, an increasing number of safety-relevant structures are designed and manufactured from carbon fiber reinforced polymers (CFRP) in order to reduce weight of airplanes by taking the advantage of their specific strength into account. ![]() Quantitative impact characterization of aeronautical CFRP materials with non-destructive testing methodsĭOE Office of Scientific and Technical Information (OSTI.GOV) ![]()
