Due to its complexity and high integration,the failure of composite forming equipment production line may involve multiple links and factors,so a systematic method is needed to accurately analyze and lo-cate the fault source.This paper sorts out the possible fault types and influencing factors in the manufactur-ing process of composite products,constructs a comprehensive fault tree of composite forming equipment pro-duction line,maps the actual fault events to the fault tree with the help of fault tree inversion technology,and obtains the basic fault events that may lead to these fault events through reverse derivation,which is of great significance in improving production quality and reducing the risk of failure,and provides strong sup-port for technological improvement and innovation in the field of composite material manufacturing.
