摘要:: X射线计算机断层扫描（X-ray computed tomography，X-ray CT）作为一种具有高分辨率、非破坏性、三维可视化等特征的材料表征测量技术，显示出独特的优势。X-ray CT不仅能得到试样的高分辨率外部特征，还能够获取其详细的内部结构信息，在各个领域已经受到越来越多的关注。通过简单比较几种无损检测技术的适用性和局限性，引出了X-ray CT的独特性，阐述了X-ray CT的原理以及实验室断层扫描和同步辐射计算机断层扫描（synchrotron radiation computed tomography，SRCT）的特点；从探索纤维增强聚合物（fiber reinforced polymer，FRP）复合材料的内部结构、评估制造过程、获取损伤失效演变以及X-ray CT与其他表征手段相结合等几个方面归纳了X-ray CT在FRP中的应用，并提出了X-ray CT在FRP研究中的挑战。

Abstract:: X-ray computed tomography (X-ray CT), as a highresolution, non-destructive, 3D visualization technology of material characterization and measurement, shows unique advantages. It can not only provide the highresolution external characteristics of the sample, but also obtain the detailed internal structure information, which has attracted more and more attention in various fields. This article highlights the uniqueness of X-ray CT by simply comparing the applicability and limitations of several nondestructive testing techniques. The principle of X-ray CT and the characteristics of laboratory tomography and synchrotron radiation computed tomography（SRCT）are mainly described. The application of X-ray CT in fiber reinforced polymer（FRP） composites is summarized from the aspects of exploring the internal structure, evaluating the manufacturing process, obtaining the evolution of damage or failure, and combining X-ray CT with other characterization methods. The challenge and development trend of X-ray CT in FRP research are put forward.
