近年来，自动纤维铺放技术已被应用于制造含有连续变化纤维路径的变刚度板。其目的是实现与直纤维层压板相比上级的机械性能[1，2]。本文提出了一种新的低成本的制造技术，在这里被称为“手动2D织物转向”。该工艺能够制造与使用自动纤维铺放生产的那些类似的可变刚度面板。通过操纵双轴织物，可以产生曲线纤维路径。该技术涉及非常低的设备成本，并可用于同时操纵多层织物（与自动纤维铺放中的逐束和逐层纤维铺放方法相反），从而导致更快的生产速度和更低的成本，至少对于较小的生产运行。计算机辅助工程工具SteerFa B [3]用于指导设计和制造过程，方法是预测：（a）最佳2D纤维路径，（B）最终可变刚度板的后续机械性能（包括抗屈曲性能的改善）和（c）实际制造过程的分步说明。在本文中，手动二维织物转向描述和最终转向织物预制件上的操作顺序的效果进行了研究。还检查了该过程的可重复性。
In recent years, Automated Fibre Placement has been applied in manufacturing variable stiffness panels containing continuously changing fibre paths. The aim is to achieve superior mechanical properties, compared to straight-fibre laminates [1,2]. This paper proposes a novel low-cost manufacturing technique, referred to here as ‘manual 2D fabric steering’. The process is able to manufacture similar variable stiffness panels to those produced using Automated Fibre Placement. By manipulating biaxial fabrics, curvilinear fibre paths can be created. The technique involves very low equipment costs and can be used to steer multiple-layers of fabrics simultaneously (in contrast to the tow-by-tow and layer-by-layer fibre deposition method in Automated Fibre Placement), leading to faster production rates and lower costs, at least for smaller production runs. A computer aided engineering tool, SteerFab [3], is used to guide the design and manufacture process by predicting: (a) the optimum 2D fibre paths, (b) the subsequent mechanical behaviour of the resulting variable stiffness panel (including improvements in buckling resistance) and (c), the step-by-step instructions for the actual manufacturing process. In this paper, manual 2D fabric steering is described and the effect of the manipulation sequence on the final steered fabric preform is investigated. The repeatability of the process is also examined.
