Defect Detection Limitations,
Abstract
The results of a continuing IR&D study on the limitations of defect detection in composite materials by a variety of nondestructive evaluation (NDE) techniques are presented. A brief description of the composite material investigated is given. Several features of computed tomography (CT) are discussed including density resolution, sensitivity of bulk density measurement, and partial volume effects caused by sloping conical surfaces, slice thickness, and reconstruction techniques. The effects of the material and liquid saturation of the material on ultrasonic waveforms are included.
