Purpose: of this paper is comparison of impact delaminations in CFRP using different test methods. Design/methodology/approach: A comparison is made between the results of well-established techniques such as Ultrasonic Testing or micrographic cross-sections with the results of Microfocus Computed X-Ray Tomography. Findings: The findings show that both Ultrasonic Testing and μCT show a linear correlation between impact energy and delaminated area. However, μCT is able to detect significantly larger delaminated areas. Other findings were that the undamaged zone immediately underneath the contact point of the impactor is not a cylinder but a cone segment. The higher density of that compacted area could also be visualized. Research limitations/implications: The correlation between main impact parameters could be shown on the base of state of the art non-destructive testing. Originality/value: Impact delaminations in carbon fiber reinforced plastic have generated in a well-defined manner and a comparison is made between the results of well-established techniques such as Ultrasonic Testing (UT) or micrographic cross-sections with the results of Microfocus Computed X-Ray tomography (μCT).
