Attenuation Characteristic Study on the Acoustic Emission Wave in Different Composite Materials

Attenuation characteristics of the acoustic emission wave in different composite containers are studied in this paper. Though measuring the attenuation on different composite containers, the effects of material structure direction, container medium, container loading history and other factors on the characteristic of amplitude attenuation are discussed. The results show that factors such as material direction and container loading history have influence on the attenuation characteristic of acoustic emission wave. These will provide data support for the following study of acoustic emission test.
