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。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.
