摘　　要：介绍了超声波喷水穿透法的检测原理及自行研制的四轴自动超声波喷水穿透C扫描检测系统。利用该检测系统对包括平板试样件,大厚度模压件,以及筒形结构件等先进复合材料进行超声波喷水穿透法检测,结果表明该方法对先进复合材料中存在的孔隙、裂纹、脱粘和分层等缺陷能有效检出。The basic theory of ultrasonic squirter transmission method and the four-axes automatic ultrasonic squirter transmission C-scan system were introduced. Several advanced composite materials including the fiat plate sample, the heavy section forming and the cylinder structure were studied by the system and method. The results show that the defects such as pore, crack, sticky point and lamination in the advanced composite materials can be effective- ly detected by this method.
