本文提出了一种方法，用于体捕获和渲染的平纹编织和多层织物细观结构内的巩固，固化层压板。微X射线计算机断层扫描（MicroCT）是一种非破坏性可视化材料微观结构的优秀工具，但对于碳纤维复合材料，丝束和树脂之间的对比度很差。首先，本文展示了通过在织物中引入更高密度的材料如金、碘和玻璃来提高microCT图像对比度的技术。两种方法被证明是有效的，以提高重建microCT可视化丝束之间的区分。其次，讨论了利用microCT扫描数据生成编织复合材料三维体积模型的方法。生成模型的过程中解释了从最初的制造与一个例子平纹织物的帮助。这些方法将用于三维织物预制件的有限元建模在未来的工作。
This paper presents a methodology for volume capture and rendering of plain weave and multi-layer fabric meso-architectures within a consolidated, cured laminate. Micro X-ray Computed Tomography (MicroCT) is an excellent tool for the non-destructive visualisation of material microstructures however the contrast between tows and resin is poor for carbon fibre composites. Firstly, this paper demonstrates techniques to improve the contrast of the microCT images by introducing higher density materials such as gold, iodine and glass into the fabric. Two approaches were demonstrated to be effective for enhancing the differentiation between the tows in the reconstructed microCT visualisations. Secondly, a method of generating three-dimensional volume models of woven composites using microCT scan data is discussed. The process of generating a model is explained from initial manufacture with the aid of an example plain weave fabric. These methods are to be used in the finite element modelling of three-dimensional fabric preforms in future work.
