Abstract

With regards to non-destructive (NDT) testing of the structural materials, the need for developing new experimental methods allowing for safe, contactless, and fast inspection, continues to rise. The phenomenon of the Terahertz imaging NDT method has been described within the presented study. In doing so, the fiber-reinforced aramid composites, that is, commonly used ballistic cover material, with intentionally introduced defects in a form of plates located at various depths below the samples’ surface, were meticulously investigated. The aim was to clearly detect the disturbances in the materials’ interior using newly developed Terahertz imaging in transmission mode. It has been concluded that the Terahertz-based method is a very effective tool in defect detection, and it allowed for the detection of each implemented flaw with high resolution. Overall, the advantages and limitations of this method in the non-invasive inspection of composites are discussed and the potential application is demonstrated.

使用太赫兹成像技术对军用复合材料进行无损检测

关于结构材料的无损检测(NDT)，开发安全、无接触和快速检测的新实验方法的需求不断增加。在本研究中描述了太赫兹成像无损检测方法的现象。在此过程中，对纤维增强芳纶复合材料(即常用的弹道覆盖材料)进行了细致的研究，故意在样品表面以下不同深度的板中引入缺陷。目的是利用新开发的太赫兹成像传输模式，清楚地探测到材料内部的干扰。结论是，基于太赫兹的方法是一种非常有效的缺陷检测工具，它允许以高分辨率检测每个实现的缺陷。总之，讨论了该方法在复合材料无创检测中的优点和局限性，并展示了其潜在的应用前景。

期刊介绍： The past few decades have seen outstanding advances in the use of composite materials in structural applications. There can be little doubt that, within engineering circles, composites have revolutionised traditional design concepts and made possible an unparalleled range of new and exciting possibilities as viable materials for construction. Composite Structures, an International Journal, disseminates knowledge between users, manufacturers, designers and researchers involved in structures or structural components manufactured using composite materials. The journal publishes papers which contribute to knowledge in the use of composite materials in engineering structures. Papers deal with design, research and development studies, experimental investigations, theoretical analysis and fabrication techniques relevant to the application of composites in load-bearing components for assemblies, ranging from individual components such as plates and shells to complete composite structures.
