Overview of application and research on advanced composite grid structures

Advanced composite grid structure (AGS) is one of the most efficient lattice structures with many potential advantages, which own good application foreground in aeronautical and space engineering. First, the overview of the excellent performance and applications to AGS in USA and Russian are presented. Then, the discussion focuses on three kinds of manufacture toolings: hybrid tooling, expansion block tooling and interlocked grid structures. Researches on mechanical properties, design and structural health monitoring are summarized. Finally, the present research state is generalized and the trends in future are described.
