Abstract :
The technique is established for performance-analysis and inner failure location of three-dimensional braided composites, which is based on the wave transmission of the acoustic emission and the equation of time location method. We have a few of failure three-dimensional braided composites which is seemed a crack on the material obviously. The crack is formed by the break yarn when the material are braiding. The difference is compared between the measure and acoustic emission detection method. Experimental results show that acoustic emission source location algorithm by the computer agreed well with the actual location.
