Abstract [eng] Air-coupled ultrasonic measurement techniques can be used for contactless measurements. Here, we demonstrate that they can be used to detect defects caused by impact damage in a pultruded glass fiber composite, which has a highly scattering structure. The images of damage have been analyzed, and the relationship to impact energy determined. The technique is also compared to signals generated via an EMAT device and a non-damaging metal patch attached to the surface of the sample.
