Analysis of Influencing Factors of Ultrasonic Nondestructive Testing with Carbon Fiber Reinforced Plastics

Abstract:

In order to research the influenced factors of sensitivity of ultrasonic nondestructive testing, the compared experiments using water immersion and contact method were carried out and the experimental results of sensitivities were obtained. The results showed that the limited sensitivities of probes with 1MHz and 2.25 MHz is very low. And the defects ofφ1mm, which distance not exceeding 1mm, can be detected by probes of 5 MHz and 10 MHz. The defects ofφ0.5mm can be detected by probes of 15 MHz and 20 MHz. The definition of defects apperance will be further improved for the probes with their frequency more than 15 MHz when the scanning step enough small. The distance of probes and defects has little effect on the detecting sensitivity.
