Abstract

Abstract: In order to study the applicability of acoustic emission technology in the test of GFRP adhesive bolted hybrid joints, the static failure tests of single lap plate joints under tensile and shear conditions were carried out, and the characteristic parameters of acoustic emission were analyzed. The results show that the acoustic emission characteristics can well reflect the failure law of GFRP adhesive bolted hybrid joints. The failure process of joints can be divided into four stages: Steady development of adhesive layer damage, rapid development of adhesive layer damage, steady development of FRP damage and rapid development of FRP damage, and the acoustic emission results are consistent with the change law of load displacement curves. However, it is difficult to locate the internal failure area of GFRP plates. The results provide a reference for the application of acoustic emission technology in similar structural tests.

Key words: acoustic emission technology, GFRP adhesive bolt hybrid joint, static test
