- 01HS0P058GABB0G9NBJAVMQZQK abstract "Fiber reinforced polymers, also called composites, obtain their good mechanical properties by adding strong and stiff fibers in a low-density polymer matrix. By optimizing the design of the fiber architecture, composites can be tailored for specific high-end applications. Small deviations from the nominal fiber architecture can have a significant effect on the structural performance. Typically, such deviations may be introduced during the manual manufacturing process (e.g. fiber wrinkles), or during the operational lifetime (e.g. excessive load). X-ray Computed Tomography (X-CT) is a well-known technique for assessing the fiber architecture in composites. X-CT yields a detailed imaging, but has also several physical limitations: it can handle only small samples (mm-range) and shows poor contrast for carbon fiber reinforced polymers (CFRP). This study proposes an alternative tomographic imaging methodology on the basis of ultrasound waves. The proposed Ultrasound Computed Tomography (U-CT) technique [1] employs a classical pulse-echo ultrasound scan, coupled to three subsequent analysis steps: • STEP-1: Extraction of the ply thicknesses by analysis of the instantaneous phase information [2, 3] • STEP-2: Estimation of the out-of-plane ply orientations by means of a structure tensor process [4] • STEP-3: Determination of the in-plane fiber angles by means of a Gabor filter-based information diagram [5] The developed U-CT technique is experimentally demonstrated on an impacted 24-layer CFRP laminate with a stacking sequence [45/0/−45/90]3S. The U-CT reconstruction of the fiber architecture reveals that the impact event did not alter the in-plane fiber angles of the laminate. Instead, the impact introduced a complex delamination cluster and induced a slight distortion of the out-of-plane ply orientations near the impact location. The results obtained by the proposed pU-CT method suggest that it could be a powerful complement to X-CT, especially for the volumetric reconstruction of CFRP laminates with sizeable dimensions.".
