Abstract

Nondestructive testing results of carbon fiber reinforced plastics (CFRP) specimens at the development and testing process are given at that paper. Ultrasonic pulse-echo technique is the most applicable for CFRP monolithic panels and curved beam specimens testing. It is shown that ultrasonic testing allows optimizing the mode in the process of developing molding modes for new CFRP grades. At the test stages it allows to exclude defective specimens from the testing process and estimate the sorts and damage sizes after the tests.
