The Application and Development of Composite Material Detection Using Dry Coupled Acoustic Technology

Abstract:

This paper focus on the method of composite material detection, and five dry coupled acoustic technologies are introduced, which are dry pressure coupling method, acoustical impedance method, Local percussion method, air-coupled ultrasonic method and ultrasonic fixed spacing pitch-catch method. The principle, character and application of these five methods are discussed, and the development trend of dry coupled acoustic technology is previewed.
