为了减少变角丝束（VAT）复合材料的丝束转向过程中的工艺缺陷，最近发展了一种新的纤维铺放方法“连续丝束剪切（D'S）”。由于CTS利用丝束材料的剪切变形，因此它与使用面内弯曲变形的传统自动纤维铺放（AFP）工艺不同。在这样做时，即使应用相同的参考丝束轨迹，也会在丝束转向面板中产生不同的纤维角度和厚度分布。在这项工作中，计算机辅助建模工具已被开发，它可以创建准确的ABAQUS有限元模型，反映非线性纤维轨迹和厚度变化的增值税复合材料制造的CTS通过定义纤维路径的几何特征，在CAD软件。(C)2015年，作者。由爱思唯尔有限公司出版。这是一篇开放获取的文章，使用CC BY许可证（http：//creativecommons.org/licenses/by/4.0/）。
A novel fibre placement method 'continuous tow shearing (D'S)' has recently been developed in order to minimise process-induced defects in a tow steering process for manufacturing variable angle tow (VAT) composites. As CTS utilises shear deformation of tow materials, it distinguishes itself from conventional automated fibre placement (AFP) processes that use in-plane bending deformation. In doing so, it produces distinct distributions of fibre angle and thickness in a tow steered panel even if the same reference tow trajectories are applied. In this work, a computer-aided modelling tool has been developed, which can create accurate ABAQUS finite element models reflecting the nonlinear fibre trajectories and thickness variations of VAT composites manufactured using the CTS by defining fibre paths with geometric features in a CAD software.
