復合材料由兩種或兩種以上不同方式組合而成，具有重量輕、強度高、加工成型方便、彈性優良、耐化學腐蝕和耐候性好等特點，廣泛應用于各行業領域。生產制造過程中工藝不合理或過程控制偏差會導致復合材料出現各種類型缺陷，如:分層、空隙、裂紋、夾雜物等。

超聲波檢測技術作為復合材料檢測中重要的一種無損檢測技術，廣泛應用與產品零部件制作過程及在役設備的定期檢修過程中。超聲波探傷儀根據超聲波在材料內部缺陷區域和正常區域的反射、衰減的差異來確定缺陷的位置和大小。

Composite materials by two or more than two different ways of combination, with light weight, high strength, convenient processing and molding, excellent elasticity, chemical corrosion resistance and weather resistance, etc., widely used in various fields.  In the manufacturing process, unreasonable technology or process control deviation will lead to various defects of composite materials, such as delamination, void, crack, inclusion and so on.  

As an important nondestructive testing technology in composite material testing, ultrasonic testing technology is widely used in the manufacturing process of product parts and the regular maintenance process of in-service equipment.  Ultrasonic flaw detector determines the location and size of defects according to the difference of reflection and attenuation of ultrasonic in the defect area and normal area of materials.
