摘要
利用建筑材料、隔热垫和胶粘剂制作了胶层中含人工空气缺陷的三层胶接结构, 并利用SynViewScan 300连续太赫兹成像系统对样件进行了检测。通过分析胶接面的太赫兹二维图像及缺陷处和正常胶粘处的单点纵向信号, 获得了胶层空气缺陷的位置和大小信息。结果表明, 连续太赫兹波成像系统可以清晰识别胶接结构中的胶层空气缺陷。
Abstract
Three-layer bonded structure containing artificial air defects within adhesive layers is manufufactured with the usage of building materials, insulation mat, and adhesive, and the specimen is inspected by the SynViewScan 300 continuous terahertz imaging system. Via analysing the two-dimensional terahertz images at adhesive surface and single point longitudinal signal within defect area and normal adhesive area, the informations about position and size of air defects are acquired.The results indicate that the continuous terahertz imaging system is capable of clear identification of air defects within bonded structures.
