Abstract This paper presents a novel methodology to derive multi-layer textile unit cells directly from μCT scans of real textile specimens. The constructed unit cells are guaranteed to be periodic and free from inter-tow penetrations. Furthermore, no assumptions with regards to the tows’ shape and spatial placement are imposed, which set the proposed technique apart from the state-of-the-art textile unit cell modelling approaches. The methodology can derive various unique unit cells with an arbitrary number of layers and nesting configurations from a given μCT-dataset, which are readily converted to finite element models that contain local information such as fibre fraction and orientation.

一种直接从 μCT 扫描构建具有随机嵌套配置的周期性多层 2D 编织单位单元的新方法

摘要 本文提出了一种直接从真实纺织品样本的 μCT 扫描中推导出多层纺织品单位单元的新方法。构造的单元格保证是周期性的并且没有丝束间穿透。此外，没有强加关于丝束形状和空间布置的假设，这使所提出的技术与最先进的纺织单元建模方法区别开来。该方法可以从给定的 μCT 数据集导出具有任意层数和嵌套配置的各种独特的单元格，这些单元格很容易转换为包含局部信息（如纤维分数和方向）的有限元模型。
