Abstract: The fiber reinforced polymer composite grid structure has the characteristics of high specific stiffness, high specific strength, high damage tolerance, and automatic forming, and has broad application prospects in aerospace structures. The stacking, bridge, bending and cutting of the fibers at the intersection of the grid structure severely affect the final performance of the structure. Aiming at the inherent defects at the intersection of the fiber reinforced polymer composite grid structure, this paper summarizes the advantages and disadvantages of filament winding, fiber placement, 3D rotary braiding, interlocked and vacuum assisted resin transfer molding process in forming grid structure. At the same time, the relationship between the grid structure design and forming process is discussed. Finally, the main problems in the current grid structure research are analyzed, and the future development direction is prospected.
