Digital design of laying process for composite prefabricated parts based on volume filling

This paper introduces the digital design and manufacturing technology and its application status of composite preforms' laying process, and points out that the digital process design technology should be developed with the practical knowledge accumulated and it eventually drive the entire workflow of digital design and manufacturing for preforms. It introduces the digital design method for laying process based on volume filling. Combining four different application examples, this paper fully elaborates on the relevant problems and solutions in the digital laying process design based on volume filling, which provide useful references for the application and promotion of digital design technology.
