Embodiment
[0060] see figure 1 , the size of the fiber layer and the plate is 300mm × 300mm × 2mm (the thickness of the upper and lower panels is 2mm). The warp yarn uses T300 3K×1 strand carbon fiber, the weft yarn 20 uses T300 3K×2 strand carbon fiber, and the normal yarn 30 uses T800 12K×1 strand carbon fiber. Process design is carried out according to the size requirements of the fiber layer connecting plate: the fabric structure adopts a 2.5D woven shallow cross-bending structure, and the design layers of warp yarns are 8 layers in total, of which the upper warp yarns 12 used to form the upper panel 600 are four layers. The upper warp yarn 16 forming the lower panel 800 has four layers, the warp density of the fabric is 8.0 threads / cm, and the weft density is 3.0 threads / cm. The intermediate layer between the upper panel 600 and the lower panel 800 is indicated by reference 700 .

Abstract
The invention discloses a method for preparing a fiber layer connecting block, which comprises the following steps: (1) initial yarn arrangement; (2) shedding movement; (3) first weft insertion; (4) second shedding movement; (5) The second step of weft insertion; (6) The third opening movement; (7) The third step of weft insertion; (8) The fourth opening movement; (9) The fourth step of weft insertion; (10) The fifth (11) the fifth step weft insertion; (12) the sixth shed movement; (13) the sixth step weft insertion; (14) repeat steps (2) to (13) until the fiber layer is connected Plate weaving. The present application also provides a fiber laminated board prepared by the above-mentioned preparation method. The thickness of the upper and lower panels of the hollow plate in the present invention can be adjusted and designed, and the size of the hollow area can be adjusted according to the consistency of the weft density, which emphatically solves the problem of thin upper and lower layers of the hollow fabric.
Description
technical field [0001] The invention relates to a preparation method of a novel fiber layer connecting plate in the field of three-dimensional woven fabrics, specifically a process design of a special normal yarn movement rule, which can be applied to the preparation of a fiber layer connecting plate. The present application also relates to the fiber laminated board prepared by the above-mentioned preparation method. Background technique [0002] Hollow composite material is a new type of sandwich composite material because it is lighter than metal materials and has higher specific strength and specific stiffness. It is widely used in rail transit, vehicle and building materials and other fields. [0003] In domestic and foreign hollow fabric patents, most of the descriptions are that the upper and lower layers are single-layer cloth, and the upper and lower layer structure is changed, such as plain weave, variable plain weave, twill weave, etc. The thickness of the upper an...
