The composite fuselage is one of the important structures of the new large commercial aircraft. The manufacturing process directly affects the product quality consistency

a multi-faceted research and verification were carried out

the stringer positioning. The process of automatic forming and other processes has completed the manufacture of the large panel. Studies have shown that the selected panel manufacturing process technology has low risk and high quality consistency

which provides the basis for the automated manufacturing of large-size panel.
