Paper Title:
Acoustic Emission Characteristics of Initial Failure for Carbon/Fabric Composite Edge Closeout
  Abstract

Edge closeout is one of the better methods for fastening composite materials to other structures. In this paper, fastened region of Carbon/Fabric composite plate edge closeout is mechanically tested. Finite element analysis and AE(acoustic emission) characteristics are utilized for comparison of test and analysis. The characteristics of AE signal used in this study are hit distributions, peak frequency of generated AE waveform and amplitude of signals. The frequency regions for failure of composite materials are under 100 kHz and 200-300 kHz for failure initiation and the ultimate failure occurred with frequency region of 300-400 kHz.
