The portable intelligent coin-tap test system of civil aircraft composite structures

Now, most NDT methods (electromagnetism testing, eddy current inspecting, ultrasonic testing and so on) of composite have own their merits or defects and range of application. This paper will introduce an intelligent coin-tap test system of civil aircraft composite structure. With the character of high automatic facility, prompt and accuracy, this system can be employed in production and maintenance field of civil aircraft composite structure.
