A cantilever beam test has been developed in order to characterize structural bondlines, especially between shear webs and spar caps of a wind turbine rotor blade. The structural integrity was monitored during static and cyclic tests with the acoustic emission (AE) technique, detecting and linearly locating the developed damage at the bondline while discriminating between different failure modes. The AE during the tests is acquired with experimental equipment supplied from Physical Acoustics, with 10 MHz maximum sampling frequency and a wideband sensor network located on the the tested component.
