采用贴膜法、插拔钢片法、脱模剂法和脱模膏法的方式制作不同尺寸及埋深的人工缺陷试块，并对其进行水浸超声检测。结果表明，水浸超声检测方法可以有效检测出复合材料层压板中由贴膜法、插拔钢片法制作的人工缺陷，但对于脱模剂法和脱模膏法制作的人工缺陷检测效果较差。该研究对碳纤维复合材料层压板人工模拟缺陷试块的制作及其超声检测具有一定的参考意义。

In this paper, the specimens with artificial defects of different sizes and buried depths were made by using sticking membrane method, inserting steel sheet method, mold release agent method and demoulding cream method respectively, and then the water immersion ultrasonic testing was carried out on them. The results show that the water immersion ultrasonic detection method can detect the artificial defects in composite laminates made by sticking membrane method and inserting steel sheet method effectively, but is insufficient to detect the artificial defects made by mold release agent method and demoulding cream method. The research work in this paper has a certain reference significance for the fabrication of specimens with artificial defect and ultrasonic inspection of carbon fiber composite laminates.
