[0002] A grid laying machine is a device for manufacturing composite materials. It precisely lays fiber bundles or fiber meshes on a mold to form the desired shape and number of layers. The outrigger of a grid laying machine generally has the following functions:
[0003] Precise positioning: The outrigger can precisely place the fiber grid at a specific position on the mold, ensuring uniform fiber distribution and meeting the design requirements.
[0004] Multi-layer laying: During the manufacturing process of multi-layer composite materials, the outrigger can move multiple times to sequentially lay fiber meshes of different layers on the mold.
[0005] Angle adjustment: The outrigger of some grid laying machines can adjust the angle to meet the fiber laying requirements in different directions. For example, when manufacturing composite materials with specific angle layers.
[0006] Automation control: The outrigger is usually connected to a computer control system and can automatically lay fiber meshes according to a preset program, improving production efficiency and consistency.
[0007] Labor reduction: The automated outrigger reduces the need for manual operation, lowering the labor intensity and the possibility of human errors.
[0008] Adaptation to complex shapes: The design of the outrigger can usually adapt to different-shaped molds, enabling the grid laying machine to be used for manufacturing composite material parts with complex shapes.
