Full Focus 3D Phased Array Ultrasonic Testing of Carbon Fiber Composites

针对209P型转向架使用碳纤维复合材料的无损检测,采用全聚焦3D相控阵超声检测技术进行试验研究。通过试验结果表明,全聚焦3D相控阵超声检测具有缺陷图像显示直观、缺陷定量准确等特点,能够实现对209P型转向架使用的碳纤维复合材料质量管控。全聚焦3D相控阵超声检测为碳纤维复合材料的检测提供了一种新思路和新途径,对复合材料的可靠性研究提供了一种有效手段。

In this paper,the Total Focusing Method(TFM)3Dphased array ultrasonic testing(PAUT)technology is used for the nondestructive testing of 209Pbogie using carbon fiber composites.The test results show that the TFM 3DPAUT has the characteristics of intuitive defect image display and accurate defect quantification,which can realize the quality control of carbon fiber composite used in 209Pbogie.TFM 3DPAUT provides a new idea and a new way for the detection of carbon fiber composites,and provides an effective means for the reliability research of composite materials.
