Abstract

Based on the concept and principle of digital twin

as well as the current promising manufacturing technologies: Automatic fiber placement based liquid composite molding

by sorting and analyzing the key links of the AFP–LCM

this article elaborates on several key issues that urgently need to be solved in the establishment of digital twinning for the manufacturing of composite material components in civil aircraft. It also proposes a systematic architecture for the manufacturing technology of composite material structures in civil aircraft based on digital twinning. This paper discusses the problems faced by the implementation of this technology from both technical and policy perspectives

and it provides strategies for the practice in-depth of digital twinning technology in the field of composite material manufacturing in civil aircraft.
