Description

technical field [0001] The present invention relates to the technical field of material defect detection and non-destructive detection technology, in particular to a material defect detection device and a material defect detection method. Background technique [0002] In recent years, various new composite materials have played an increasingly important role in the construction of aircraft structures, and are even used in key parts related to flight safety. Among them, a new composite material with a laminated porous structure with strong sound absorption properties is the most common. The material is a fiber-reinforced metal material formed by alternate lamination and binding of high-strength aluminum sheets and high-strength glass fiber-reinforced resins, and the internal porosity is greater than 90%. During the production and use of this material, due to the influence of factors such as manual operation, environment, and external load, there will inevitably be defects su...
