Description

Technical Field

[0001] The present invention relates to the technical field of composite material preparation, and particularly relates to a composite material laying device. Background Art

[0002] Composite materials composed of reinforcing fibers and resins have been widely used in different fields due to their excellent properties such as light weight, high strength, strong plasticity, and integral parts. A composite material laying device is a device specifically used for manufacturing composite material products. Its main function is to lay various reinforcing fibers and resin matrices together according to a predetermined thickness, angle, and order, and then cure them into composite material products through heating and pressure. Reinforcing fibers have the characteristic of anisotropy, that is, the mechanical properties of the warp direction (0° direction) and weft direction (90° direction) of the reinforcing fibers are different. To avoid the influence of anisotropy on composite material products, when laying reinforcing fibers, it is usually necessary to perform 0° mirror laying of ns layers, or mirror laying of a combination of 0° and non-0° of ns layers, that is, mirror symmetry laying of all 0° layers, or mirror symmetry laying of a combination of 0° layers and non-0° layers. Among them, in the mirror symmetry laying of a combination of 0° layers and non-0° layers, the warp direction of the reinforcing fibers has the same direction as the laying direction and has a non-0° included angle with the laying direction, so that the warp directions of the reinforcing fibers in each layer can be evenly arranged along the non-0° included angle direction, reducing the adverse influence of the anisotropy of the reinforcing fibers on the composite material products, realizing the balanced arrangement of the mechanical properties of the reinforcing fibers in the laying layer, and avoiding the occurrence of tensile and torsional coupling, and preventing warping deformation during the processing.

[0003] To achieve symmetric laying, a feasible method is to configure two groups of material rolls. The warp direction of the reinforcing fibers in one group of material rolls is consistent with its extending warp direction, and the warp direction of the reinforcing fibers in the other group of material rolls forms a non-0° included angle with its extending direction; by changing the lead-out directions of the two groups of material rolls, 0° mirror laying of ns layers, or mirror combination laying of 0° and non-0° of ns layers can be achieved. Since it is difficult to control the included angle between the warp direction of the reinforcing fibers and their extending direction in each group of material rolls, the symmetry of the laid reinforcing fiber layers is poor; it is difficult to achieve an ideal mirror-symmetric laying layer prepared from two groups of material rolls without the assistance of a matching device, resulting in inconvenient operation and low laying efficiency. Therefore, the existing composite material laying devices are difficult to effectively achieve symmetric laying. Summary of the Invention

[0046] and drive the starting end of the fabric 12 to move to the right, so that the fabric 12 is unfolded from left to right on the layup table 2; then cut the unfolded fabric 12 into plies through the cutting device.
