Analysis of Ultrasonic Backscatter for Porosity Characterization in Graphite-Epoxy Composites

  • Ronald A. Roberts

Abstract

This paper summarizes recent work on the use of ultrasonic back-scatter for the estimation of porosity levels in continuous-fiber-reinforced, layered graphite-epoxy composites. This work is a continuation of previous work described in Refs. 1–3, which addresses the effect of porosity on (1) azimuthal angle backscatter scans, and (2) the spectral characteristics of backscatter.
