What is Ultrasonic Testing of GRP-Rubber Defects about?

This paper discusses the ultrasonic non-destructive testing of GRP-Rubber composites to detect internal defects such as bubbles and degumming, which can impair performance. The study employs a 5MHz ultrasonic probe and various imaging methods, successfully detecting artificial defects down to 2mm in size. Results indicate that the peak-to-peak imaging method provides the most accurate defect area measurements, while the positioning of the detection gate significantly influences imaging outcomes.
