Volumetric visualization of ultrasonic NDE of composite laminates
- Univ. of Delaware, Newark, DE (United States). Center for Composite Materials
The need to detect the onset and location of damages in composite laminates has led to the development of new visualization methods for ultrasonically obtained NDE data. Over the years, ultrasonics have been established as one of the principal investigation techniques for nondestructive evaluation of composite structures. Ultrasonic NDE methods have been employed successfully for the detection of horizontally located defects such as delaminations, contaminations, impact damage, etc.. However, traditional ultrasonic C-scans have been limited in reliably detecting vertically oriented damages in a composite laminate such as matrix cracking. State-of-the-art image enhancement techniques have been developed and applied to aid the inspector in the interpretation of ultrasonically obtained results. These methods include algorithms to highlight particular information about the composite such as matrix rich or poor areas, and fiber orientations. For a more detailed inspection of the composite laminate a digitized full-volume inspection method is being utilized. To this end, several novel visualization and enhancement software packages are being applied. The paper introduces and describes the ultrasonic NDE, image enhancement, and advanced visualization methods and analyzes the obtained results.
