Abstract
In this paper emphasis is placed on the analysis and characterization of the emission associated with matrix splitting, giving special attention to distinguishing the emission generated by actual damage progression from that generated by friction. For this purpose, double-edge notched unidirectional graphite/epoxy AS/3501-6 specimens were subjected to uniaxial tension-tension (R = 0.1) cyclic loadings. Acoustic emission was monitored using the various AE event intensities, i.e., event amplitude, duration, energy, and counts, which were analyzed in detail.Keywords
