Acoustic Emission Detection of Composite Pressure Vessle

Ren Rongzhen; Yuan Zhenmin(Institute of Aeronautical Materials, Beijing) Hou Jidong(Institute of Space Medico-Engineering)  
The pressure cylinder being made of aramid fiber reinforced resin matrix composite has been studied by means of acoustic emission technique.The resutls show that the Felicity's ratio is an important acoustic emission parameter for evaluating the inner failure of a pressure cylinder and has a direct effect on blasting strength.High amplitude events can be indications of a cylinder blast.
