Application and Development of Faster Non-deatructive Testing Technology in Composite Materials

The application of rapid nondestructive testing technology in composite material testing is discussed. According to the structural characteristics of different kinds of composite materials, the characteristics of nondestructive testing technologies such as ultrasonic imaging testing, ray imaging testing, infrared thermal imaging testing, laser electronic speckle pattern interference imaging testing and terahertz are analyzed. According to the requirements of the internal quality of composite material testing for rapid nondestructive testing technology, combined with the shortcomings and existing problems of rapid nondestructive testing technology, the development trend of rapid nondestructive testing in the future is prospected.
