Abstract

Ultrasonic NDT is one of the most frequently applied methods for testing of composite materials. A measured wave velocity gives information about composite properties. A change in the velocity indicates possible presence of a defect. Application possibilities of air-coupled ultrasonic technique for investigation of the Lamb wave propagation in the composite material and the numerical simulations of the Lamb wave interaction with the delamination type defect are presented. The Lamb wave velocities are measured in delaminated and defect-free areas of the composite material GLARE. The delamination position influence on the Lamb wave propagation velocity is investigated experimentally and numerically.
