| Abstract: | The technique is established for performance-analysis and inner failure location of the three-dimension braiding composite material,which is based on the wave property of the AE and the theory of least square method.The difference is compared between the industrial CT scan and AE detection method.Experimental results show that AE source location agreed well with the actual location. |
| Keywords: | three-dimensional braided composite material acoustic emission source location least square algorithm surface braiding angle |
