Influencing Factors of the Attenuation Coefficient of the Ultrasonic Testing for Composite Porosity

More Information
  • Received Date: June 28, 2018
  • The influencing factors of the attenuation coefficient for porosity testing of composite are studied in this article. The experiments of changing the test frequency, probe type, water distance and the material to measure the influence to the attenuation coefficients are done. The results show that the higher the detection frequency,the bigger the attenuation coefficient, the bigger the probe beam width,the bigger the attenuation coefficient, and the acoustic attenuation coefficient of different material systems is different.
