摘要: 自动铺丝是实现复合材料机身角片自动化制造的一种重要工艺方法。路径规划是自动铺丝过程中的关键因素,铺丝路径会影响该类零件在自动铺丝过程中的纤维角度偏差、覆盖性及铺放效率等。本文对树脂基复合材料机身角片的铺丝路径作两种设计及分析,对固化后零件质量进行分析,探索铺丝路径对零件质量的影响。结果表明:对于该零件的自动铺丝,搭接-间隙铺丝路径的纤维角度偏差优于完全间隙铺丝路径的纤维角度偏差,但其覆盖性和铺放效率比完全间隙铺丝路径的差。当使用自动铺丝铺放、单侧模具固化时,这两种铺丝路径会对零件的外观及厚度产生不同程度的影响。

Abstract: Automated fiber placement (AFP) is one of the significant processes to realize manufacturing composite fuselage shear tie automatically. Path planning is the key factor of the AFP process, fiber placement path will affect the fiber angular deviation, covering and efficiency, etc. In the present study, two fiber placement paths for polymer matrix composite fuselage shear tie were designed and analyzed, also the two cured parts were inspected to explore the quality effect related on fiber placement path. The results show that for the AFP process of this part, angular deviation of the overlap & gap mixed fiber placement path is better than that of gap only fiber placement path, but its covering and efficiency are worse than that of gap only fiber placement path. For the shear tie by AFP and single-side mould, these two different fiber placement paths have a different degree of effect on appearance and thickness of the part.
