Paper Abstract

We conducted the delamination detect test for composites plate using the Brillouin optical correlation domain analysis (BOCDA) method. Firstly, a hole-assisted-fiber was chosen for embedding optical fiber sensor in order to avoid the increase of optical transmission loss induced by embedded into composite plate. The hole-assisted-fiber is functional better than comparing with the telecommunication optical fibers when optical fiber sensor was embedded into composite. Secondly, a delamination propagating was detected by the BOCDA from Brillouin peak frequency distribution and Brillouin gain spectrum shape changes.
