Abstract

The research results and curves built on the developed mathematical algorithm of probability detection of defects by their size and also the comparative analysis of testing results reliability by using the ultrasonic phased arrays and single element piezoelectric convertor are shown. It is shown that probability of defect detection for ultrasonic testing of the monolithic CFRP structures by phased array technique is considerably higher than by using traditional piezoelectric transducers.
