Based on the analysis of the composite material and its advanced manufacturing technology, with the process of fiber placement, an analysis technology of composite material fiber placement based on triangular mesh was proposed. The paper summarizes the current approach and the equidistant path planning method integrating the analysis mechanism, and we analyzed the targets of turning radius and angular deviation on the center lines. Through the result of analysis, we established the partition mechanism. With the mechanism, the original surface area of the ply was divided into some sectors independent to fiber geometry generation to improve the quality of the composite product. The CATIA secondary development tool CAA was used to realize the function of generation and analysis of the fiber geometry on the Microsoft Visual Studio 2005 platform, and the correctness of the analysis result and the partition result was validated. This research provides an important idea for the development of advanced manufacturing technology of composite materials.%通过对复合材料及其先进制造技术进行分析,结合铺放工艺性,提出基于三角网格的复合材料丝束可铺放性分析技术.在现有丝束基准路径和等距路径规划方法中融入分析机制,并系统分析丝束中心线转弯半径和角度偏差等指标.通过分析结果建立分区机制,将原铺层面进行区域划分,并独立进行丝束几何规划,提高制品质量.结合CATIA二次开发工具CAA在Microsoft Visual Studio 2005平台上实现丝束几何生成与分析功能,并对分析结果与分区结果的正确性进行验证.此研究为复合材料先进制造技术的发展提供了重要思路.
