摘要：

The ultrasonic buffer rod used for polymer testing under the high temperature, not only needs high transmission ultrasound characteristic of SNR, but also low acoustic attenuation, high temperature and strong mechanical properties etc are needed. The role PEEK rod plays in this paper is transmitting ultrasonic guided waves and temperature buffer, so the design of PEEK rod is the key. Through the experimental analysis, the SNR with different diameter and length is gave, and the effect on the ultrasonic characteristics of echo signal is also presented, in order to ensure the high SNR. The conclusions provide a theoretical basis for NDT. © 2015, SERSC.
