Sandwich structuresare widely applied in automotive lightweight, load-bearing and energy absorption structures. Different manufacturing processes make significant differences on the mechanical performance of sandwich core materials. The manufacturing technologies and development statuses of composite sandwich structures are reviewed in this paper. The structural characteristics, application scenarios and load cases of sandwich structures which are manufactured by interlocking method are analyzed and discussed in detail, it is found that this method has unique superiority. Finally, the development potential of interlocking method in the preparation of honeycomb structure is summarized, and its future development direction is prospected.
