Ultrasonic Imaging Technique for Evaluation of Interlaminar Defect in Carbon Fiber-Reinforced Composites
摘 要
针对复合材料层压结构层间界面缺陷的无损检测与评估, 通过分析超声波在碳纤维增强树脂基复合材料中的传播规律, 研究入射声波在复合材料中的反射特性, 利用入射声波在复合材料层间界面产生的反射信息, 通过超声(B, T)扫描成像方法揭示复合材料层间界面缺陷及其三维分布。试验结果表明, 采用短波长脉冲超声成像检测技术, 可以有效地再现碳纤维增强树脂基复合材料层压结构中层间界面缺陷三维分布特征以及层间界面、铺层方向、纤维束取向等信息, 为复合材料提供了一种有效的层间界面结构表征和缺陷检测方法。
Abstract
A 3D ultrasonic imaging technique by using B-scan and T-scan imaging methods, based on sonic information resulting from reflections of probe beam at interlaminar interface, was employed to non-destructive evaluation (NDE) of interlaminar defects in carbon fiber-reinforced/resin matrix laminates. The experimental results had shown that the interlaminar interface, interlaminar defects, their topologies as well as lay-up of the laminate were seen well by means of the ultrasonic imaging approach. It provided an effective instrument for NDE of interlaminar defects and characterization of bulk microstructure in composites.
