In this paper, some latest developments of non-destructive testing (NDT) techniques, such as Laser-based Ultrasonic, Air-coupled Ultrasonic, Lamb waves, Thermography, Laser-Shearography, Industrial CT, Real-Time Imaging of X-Ray, Electromagnetism and Eddy Current, applied in the fields of composite materials and manufactures are introduced briefly. In succession, author indicates that the innovations and integrations of NDT technologies, the correct characterization and the accurate quantification to defects by non-destructive evaluation (NDE) means, and standardization of NDT methods for advanced composites will become some very interesting and magnetic subjects in the future. Besides, the reality and representative of man-made defects will also be a noticeable problem for improvement of NDT technology.
