fiber direction, also known as the 0° specimen. The test of specimen C was carried
out to simulate the process of the resin cracking, debebondin, pulled out and fiber
fracture, and obtained AE signals.
20.2.2 Equipment and Procedure
The acoustic emission device: AMSY-6, 22-channel, Germany. Both hardware
system and software system were included, and it could display the waveform and
parameter data list of acoustic emission signal and various types of charts in real
time. The threshold value in the experiment is set as 40 dB.
The VS150 sensors were fixed at both ends of the specimen, with a bandwidth of
100–450 kHz, connected to the channel No. 1 and No. 2 of the device respectively
。 The VS900 sensor were fixed in the middle of the specimen, with a bandwidth of
100–1000 kHz, connected to channel No. 3 of the device. The sensors and specimen
are coupled by grease and fixed by the tape.
