Abstract

With composite materials more and more widely used in the aerospace industry

the laser ultrasonic technique has been considered as an emerging advanced nondestructive testing technique. The principle and advantages of the laser ultrasonic technique have been analyzed

and the current development of the application of the technique in the areas of nondestructive testing of Laminate structure

complex composite structure

honeycomb sandwich structure

thermoplastic composites

and the evaluation of porosity has been discussed. A brief cost analysis of this technique has also been given in this paper. Finally

the existing problems and the future development trend of the application of the nondestructive testing technique in composite structures have been described. It has certain reference for the research and application of laser ultrasonic on the composite structure.
