Abstract
Widely use of composite structures such as fiber-reinforced composites advances the demand for reliable and effective techniques of ultrasonic nondestructive testing. The model to calculate acoustic field around anisotropic materials is introduced, including propagation and penetration model of Gaussian beams in front of and behind the composites. Simulation and experiments on transmitted acoustic field of composites with different thickness were conducted. Some characteristics of ultrasonic filed around composite materials, such as focal distance and beam spread have been researched theoretically and experimentally. The accuracy of the proposed model is verified by the comparison of the model-based predictions with the experimental results. The achievement will be useful for detecting the defects inside of composites nondestructively.
