摘要

基于实验室来源的x射线断层扫描，提出了一种表征弹性体复合材料中填充团块形貌分布的新方法。开发了各种特征提取方法(通过图像处理滤波器、分割)和选择工具(Spearman等级相关系数)，结合K-means无监督聚类算法，用于识别模型材料(碳填充乙丙二烯单体橡胶)中不同的形态类别。通过精确区分具有不同加工参数的复合材料，证明了该方法的趣味性。例如，在这个例子中，由于这个分析，发现在内混炼器中弹性体之前引入填料倾向于更有结构的团聚体。

QUANTITATIVE ANALYSIS OF CARBON BLACK AGGLOMERATE MORPHOLOGY IN ELASTOMER COMPOSITES BASED ON X-RAY TOMOGRAPHY BY MEANS OF NUMERICAL CLUSTERING

A novel methodology for characterizing the morphology distribution of filler agglomerates in elastomer composites is presented based on laboratory-sourced X-ray tomography. Various feature extraction methods (via, e.g., image-processing filters, segmentation) and selection tools (Spearman's rank correlation coefficient) combined with K-means unsupervised clustering algorithm were developed for identifying the distinct morphological classes in model materials (carbon-filled ethylene propylene diene monomer rubber). The interest of this methodology was demonstrated by precisely differentiating the materials compounded with different processing parameters. For instance, in this example, thanks to this analysis, it was found that introducing the filler before the elastomer in internal mixer tends to favor more structured agglomerates.
