Application of Acousto-Ultrasonics to Quality Control and Damage Assessment of Composites

  • Ramesh Talreja

Abstract

The paper deals with application of acousto-ultrasonics to two areas of composites engineering: quality control of manufacturing composite components and assessment of damage incurred due to service loads.

The basis of analysis presented is a set of factors, called the stress wave factors (SWFs), proposed earlier by the author. The technique developed to obtain these factors is described and its application is illustrated on two specific examples: 1) quantitative evaluation of the quality of fabrication of ring-shaped, filament-wound specimens of graphite-epoxy and 2) quantitative assessment of the extent of impact damage in a graphite-epoxy laminate.
