Determination of the depth of folds in fiberglass products using ultrasonic waves

Abstract

The article discusses the existing methods of ultrasonic testing of polymer composite materials, reflected in the literature, allowing to determine the size of discontinuities, a method is proposed for determining the depth of folds of fiberglass products of complex shape by subsurface ultrasonic waves using original ultrasonic piezoelectric transducers with conical waveguides designed and manufactured. An experimental development of a method for determining the depth of folds of fiberglass products and a comparison of the results of ultrasonic testing with the results of X-ray computed tomography was carried out.
