Ultrasonic testing of metal materials has been widely applied.

Composite structures consisting of a variety of materials have to withstand high temperature, high speed, high pressure thermal ablation and erosion, the working environment is harsh, so each component has a high degree of reliability, nozzle metal shell and non-metal bonding interface, due to the bonding work piece cleaning is not clean, the lining and the outer shell is not tightly matched, the glue layer internal gas It is very easy to produce debonding, especially large area gap debonding, which is harmful to the reliability of the products. Therefore, nondestructive testing of the bonding quality of the bonding interface is also the key process of the quality control in the production of solid rocket motor. The research of nondestructive testing technology for the parts and components of the motor has been widely used in ultrasonic testing of metal materials. Composite materials have the characteristics of high anisotropy, large acoustic attenuation and complex structure. Ultrasonic testing of composite materials and their components is a weak link. It was reported in the "Ultrasonic Inspection of Engines" that they had successfully inspected the bonding surface between the non-metallic cladding layer and the steel shell by the ultrasonic multiple reflection method. After years of research, the bonding quality of the metal shell and the non-metal bonding interface of the nozzle was inspected by the ultrasonic longitudinal wave multiple reflection method. It has been successfully used now. Batch inspection of products.
