Abstract
To detect the debond defects in the foam sandwich structure material with aluminum panel,ultrasonic multiple echo-pulse method was performed.The method principle was analyzed,the artificial defect samples were made,and the automatic C-scan imaging detection was performed.The defect recognition results were analyzed by statistic calculation of the scan image gray pixel numbers.The result shows that the ultrasonic multiple echo-pulse method is effective on debond defect detection of the foam sandwich structure material with aluminum panel and provides basis for material research and evaluation.关键词
