摘要
为实现大尺寸壁板铺丝技术的工程化应用,首先对国产高强中模热固性T800级单向带预浸料进行自动铺丝工艺参数及转弯半径获取实验,基于响应曲面法、最大黏接力原则确定该材料自动铺丝工艺参数窗口,以工艺规范作为评价标准,进行转弯半径铺丝实验,获取该材料最小转弯半径。其次,使用TORFIBER轨迹规划与仿真软件对大尺寸壁板零件进行铺丝轨迹规划,结合零件结构特征和材料特点,筛选最佳铺丝轨迹生成算法,对生成的铺丝路径进行局部优化调整以提高铺丝质量;最后,基于材料铺丝工艺参数窗口,使用M. TORRES龙门式铺丝机完成了零件的铺丝制造,零件铺丝后表面质量、固化后内部无损质量满足设计指标要求。
To realize the engineering application of automatic fiber placement(AFP) technology for large size wing panels, firstly,the parameters for AFP and turning radius of domestic thermosetting T800 unidirectional belt prepreg with high strength and medium modulus were obtained. Based on the response surface method and the principle of maximum bonding force,the window of AFP parameters of the material is also determined. Based on the standard of process specification,the minimum turning radius of the material was obtained through the wire laying test of turning radius. Secondly, the laying path of large size panel parts by trajectory planning and simulation(TORFIBER) software was generated. Consider of the structural characteristics and material characteristics of the part, the best algorithm for generating laying path was selected, the laying path to improve the laying quality was adjusted. Finally,based on the window of material laying process parameters, the wire laying manufacturing of parts with M. TORRES gantry AFP machine was completed,the surface quality and the internal quality met the requirements.
