Abstract:
Traditional ultrasonic methods are commonly used to detect delamination in composite materials. However, recent advanced techniques have enabled the identification of matrix defects even in simple tension-loaded specimens. This study aims to investigate matrix splitting and delamination caused by low-energy impacts on quasi-isotropic carbon/polyetheretherketone (PEEK) laminates using a variety of pulse-echo inspection methods. C-scan imaging at normal incidence is used to detect traditional amplitude and time-of-flight separations, while angled C-scans allow the detection of matrix cracks through the laminate thickness. The results of ultrasonic testing on impacted carbon-fiber reinforced PEEK specimens are presented and compared with X-ray findings to demonstrate the effectiveness and accuracy of the proposed inspection technique.
