Application and Development of NDT for Fiber Reinforced Polymer Matrix Composites Used in Aviation
-
摘要: 近年来，国内航空用纤维增强聚合物基复合材料及制件的无损检测技术获得了较大提高，实现了多种制造工艺、多种复杂结构的可靠检测，同时，除超声、X射线等常规检测方法外，红外热像、激光散斑、空气耦合、超声相控阵等新技术也开始在复合材料检测中应用。今后，航空用复合材料无损检测技术还将结合现代电子信息、计算机等先进技术，向规范化、自动化和多元化方向发展。Abstract: The level of NDT technology for the composite used in aviation is recently raised evidently. The parts with sandwich, curvature, R-angle and cavity structure can all be inspected reliably. In addition to the conventional NDT methods of ultrasonic and X ray, the new NDT methods of infrared thermograph, laser speckle, air-coupled ultrasonic and ultrasonic phased array etc are all applicable for the composite. In the future, NDT technology for composites used in aviation must be combined with the advanced technology of electronic information, computer and so on, and developed in the normalized, automated and diversified way.
