Description

This paper will report on the results of a study of the application of advanced digital data acquisition technology to the problem of impact damage in composites. This area was chosen for the study because of the importance of developing better damage characterization methods and the limited scope of the damage itself. Low energy impacts on composite specimens typically produce very small indentations at the impact site and internal delaminations at the interfaces between lamina. Thus, one can very accurately set the ultrasonic time gates for imaging the delaminations on a layer-by-layer basis.
