Description

The method presented to detect and quantify the porosity value content of composite materials is part of a development effort to establish an integrated ultrasonic evaluation system 1. The overall research effort aims to automate the NDE process and predict mechanical and structural properties of composite materials using NDE techniques. The ultrasonic NDE technique used herein is based on digitized waveforms obtained from pulse-echo scans. For the fast integration of new algorithms into the system, a software framework was created with compatability between the signal and image processing modules. The porosity volume content of the test specimens is related to statistical properties of the ultrasonic data rather than to the ultrasonic attenuation with respect to frequency2.
