| Abstract: | A method of characterizing two major failure processes in graphite/epoxy compositestransverse 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. Each damage process was found to have a distinctive AE output and to follow a definite trend which was significantly affected by moisture conditions. 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. |
