| Abstract: | The status of composite’ s porosity ultrasonic testing in recent years was introduced in this research, four major kinds of ultrasonic testing methods are attenuation method, sound velocity method, acoustic impedance method and reference block method were elaborated. The various methods of the theoretical model, detection errors were analyzed, their advantages and disadvantages were compared and analyzed. Finally, a research direction and ideas were put forward for the future development of ultrasonic testing in composite’ s porosity. |
