碳纤维预浸带切割剪裁平台系统研究

Research on System of Prepreg Tape Cutting Platform

自动铺带技术是碳纤维复合材料的重要成型技术。根据最新提出的预浸带切割和铺放分离的"两步法"铺带技术,详细探讨预浸带切割平台的设计方案。设计方案包括预浸带双刀切割试验平台设计和搭建,基于自动铺带轨迹规划软件的双刀切割轨迹算法的研究和切割信息的植入,以及试验探究切割平台双刀切割典型边界所存在的问题及试验误差分析,以期为"两步法"铺带的研究提供基础。

Automatic tape laying is the key molding technology of advanced composite material. According to the Two-step automated tape laying （Two-step ATL） technology which parts the process of shear with laying prepreg newly proposed, the design of prepreg tape cutting platform is discussed in detail in this paper. The design includs designing and building the prepreg tape cutting platform with double cutters, the research of double cutters cutting track algorithm based on the automatic tape laying trajectory planning software and the implantation of cutting information. In the end the pos- sible problems cutting typical boundary on this platform is explored by the test, and error analysis of the platform is given. This research provides basis for the development of two-step ATL,
