Automated fiber placement (AFP) is an important process used for fabrication of composite structures. Path planning is one of the important steps in the process of AFP. The rationality of the path is directly related to the quality of the composites component. However, the generation of the placement path is constrained by a variety of factors, including geometry characteristics of curved surface, prepreg tow deformation performance, compaction roller deformation characteristics and capabilities of AFP machine. Unreasonable planning parameters selection will lead to local placement path failure or even entire path planning failure. Thus, this paper deals with making some necessary analysis about the placement suitability before path planning and then selecting the appropriate parameters, including the tow width series, compaction roller specifications and AFP machine type. The selection of suitable planning parameters can reduce the unreasonable risk of path planning and then improve the efficiency of path planning.

自动纤维铺放（AFP）是用于制造复合结构的重要过程。路径规划是AFP过程中的重要步骤之一。路径的合理性直接关系到复合材料组件的质量。然而，放置路径的产生受到多种因素的限制，包括曲面的几何特性，预浸料丝束的变形性能，压实辊变形特性和AFP机器的性能。选择不合理的规划参数将导致局部放置路径失败，甚至导致整个路径规划失败。因此，本文涉及在进行路径规划之前对放置的适用性进行一些必要的分析，然后选择合适的参数，包括丝束宽度系列，压实辊规格和AFP机器类型。选择合适的规划参数可以减少路径规划的不合理风险，进而提高路径规划的效率。
