The work presented here concerns the methodology for the analysis of X-ray micro-CT scans of composite materials with a discontinuous phase. An automatized method has been devised for the measurement of geometric features and identification of distinct morphological types. This approach offers new insights into the composition of a microstructure based on the analysis of phase morphology and its relative volume percentage. It stays in contrast to the frequency-based approach that attributes the same importance to all elements of the structure, and is thus biased towards numerous, but not necessarily essential components of the material. The method is general and can be applied to any type of discontinuous, dispersed phase in composites identified with X-ray micro-tomography. We have verified our approach for short natural fibers but it may be of interest for characterizing void distribution in RTM manufactured composites or cracks after failure.

本文介绍的工作涉及具有不连续相的复合材料的X射线微CT扫描分析方法。已经设计出一种自动化的方法来测量几何特征和识别不同的形态类型。这种方法基于对相形态及其相对体积百分比的分析，为微观结构的组成提供了新的见解。它与基于频率的方法形成对比，后者将结构的所有元素都具有相同的重要性，因此偏向于材料的众多但不一定是必不可少的组成部分。该方法是通用的，可以应用于通过X射线显微断层扫描识别的复合材料中的任何类型的不连续，分散相。
