摘要：

A method of characterizing two major failure processes in graphite/epoxy composites-transverse cracking and mode I delamination, has been studied. Representative laminates were tested in uniaxial tension and flexure. The failure processes were monitored and characterized by acoustic emission (AE). The effects of moisture on AE were also investigated. It was concluded that AE can serve as a useful tool for detecting and identifying these failure modes in composite structures in laboratory and in service environments.
