To　improve　the　inspection　ability,　the　integrated　technology　based　on　electromechanical　impedance　(EMI)　and　ultrasonic　guided　waves　techniques　was　proposed　for　defect　detection　and　localization　in　composite　plate.　Structural　health　monitoring　technology　based　on　EMI　technology　has　the　advantages　of　high　local　sensitivity,　non-model　analysis,　etc.　It　has　unique　advantages　in　the　field　of　on-line　monitoring　of　new　material　structures,　such　as　composite　structures　for　aircraft　and　spacecraft.　Ultrasonic　guided　waves　monitoring　technology　has　the　advantages　of　high　detection　efficiency,　wide　detection　range　and　fast　detection　speed.　It　is　particularly　suitable　for　health　monitoring　of　plate-like　structures.　This　integrated　technology　based　on　EMI　and　ultrasonic　guided　waves　techniques　combines　the　advantages　of　the　local　high　sensitivity　of　EMI　technology　and　wide　detection　range　of　ultrasonic　guided　waves　technology.　Results　show　that　local　averaged　value　imaging　method　and　data　fusion　algorithm　can　be　used　for　data　processing　and　fusion　of　structural　health　monitoring　of　composite　plate.　The　location　and　imaging　of　the　defects　in　the　whole　composite　plate　are　achieved.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
