| Popis: | Glass fiber reinforced plastics (GFRP) have been widely used for wind turbine blades because of the relative ease of manufacturing them into complex shapes, and their excellent fatigue and corrosion resistance. Acoustic emission (AE) testing has become a primary method for monitoring fiber reinforced plastic structures. However, commercial PZT based AE sensors for general usage may not be useful for GFRP wind-turbine blades because of the acoustic mismatching between GFRP and AE sensors. The objective of this study is to develop high sensitive AE sensors for use on GFRP. To accomplish it, PZT based 1–3 composite and PMN–PT single crystal AE sensors were fabricated and their performances were compared with PZT AE sensor. As results, the PZT based 1-3 composite and PMN–PT AE sensors showed better performance than the PZT AE sensor. PZT based 1-3 composite and PMN–PT AE sensors will be promising alternatives to PZT AE sensors for GFRP materials. |
