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 possible 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.
