Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically to a composite board reinforced with an internal interlaced fiber layer. Background Technology

[0002] Composite panels, as an important structural material, are widely used in construction, transportation, aerospace and other fields. Traditional composite panels mostly use unidirectional fiber reinforcement or isotropic core layer structure, which has problems such as large differences in mechanical properties in different directions and insufficient impact resistance. This results in insufficient overall rigidity of the panel and easy bending deformation. At the same time, the functions of existing composite panels are relatively simple, often focusing only on structural strength while neglecting the functional requirements of waterproofing, fireproofing, and antibacterial properties. Moreover, the edges of the panel are easily damaged by stress concentration or external erosion, affecting the overall service life. Therefore, we propose a new type of composite panel with built-in interlaced fiber layer reinforcement. Utility Model Content

[0003] The purpose of this invention is to provide a composite board reinforced with an internal interlaced fiber layer, in order to solve the problems mentioned in the background art, such as large differences in mechanical properties in all directions, single function, easy damage to edges, and short service life of traditional composite boards.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a composite board reinforced with an embedded interlaced fiber layer, comprising an upper panel, a lower panel, and an interlaced fiber layer disposed between the upper panel and the lower panel. A composite protective layer is disposed on the outer side of both the upper panel and the lower panel, and a composite functional layer is disposed on the inner side of both the upper panel and the lower panel. The interlaced fiber layer comprises multiple fiber mesh layers and fillers filling the spaces between the fiber mesh layers.

[0005] Preferably, the fiber mesh layer comprises multiple interwoven fiber filaments forming a perforated mesh structure, the filler and the fiber mesh layer form an integral structure, and both the upper and lower sides of the filler are connected to the composite functional layer.

[0006] Preferably, the fiber mesh layer has a square mesh shape, and there are at least three fiber mesh layers stacked together, with the upper and lower fiber mesh layers arranged symmetrically with respect to the middle fiber mesh layer.

[0007] Preferably, the composite protective layer includes a moisture-proof layer, which is respectively adhered to the outer surfaces of the upper panel and the lower panel, and a transparent wear-resistant layer is adhered to the outer surfaces of the moisture-proof layer.

[0010] Preferably, the interwoven fiber layer is bonded with an edge sealer around its perimeter, and the edge sealer and the interwoven fiber layer form a closed reinforcing unit.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: This invention disperses stress by setting interlaced fiber layers, ensuring the basic mechanical strength of the board. The top and bottom panels provide excellent surface flatness and in-plane stiffness. On this basis, the outer composite protective layer directly resists external wear, moisture and corrosion, greatly extending the service life. The inner composite functional layer provides additional functional protection such as fireproofing, heat insulation or antibacterial properties for the core structure.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model embodiment provides a composite board with built-in interlaced fiber layer reinforcement, such as Figure 1As shown, it includes an upper panel 1, a lower panel 2, and an interlaced fiber layer 3 disposed between the upper panel 1 and the lower panel 2. The upper panel 1 and the lower panel 2 serve as the main load-bearing surface layers, providing excellent surface flatness and in-plane stiffness, and are usually made of thin metal sheets or non-metallic sheets. The outer sides of the upper panel 1 and the lower panel 2 are provided with a composite protective layer 4, which is used to directly resist external wear, moisture and other environmental erosion. The inner sides of the upper panel 1 and the lower panel 2 are provided with a composite functional layer 5, which provides additional functional protection such as fire resistance and antibacterial properties for the core structure.

[0016] Furthermore, such as Figure 3 and Figure 4 As shown, the interlaced fiber layer 3 includes multiple fiber mesh layers 31 and filler 32 filling the spaces between the fiber mesh layers 31. The main extension directions of the fibers on the fiber mesh layer 31 are set at an angle α, which is 90°. The fiber mesh layer 31 includes multiple interlaced fiber filaments 311 woven into a perforated mesh structure. The filler 32 forms an integral structure with the fiber mesh layer 31. The upper and lower sides of the filler 32 are connected to the composite functional layer 5. This structural design enables the fibers to bear and disperse stress in multiple directions, significantly improving the isotropic mechanical properties of the board. The fiber mesh layer 31 is usually made of mesh fabric woven from glass fiber, carbon fiber or basalt fiber, while the filler 32 can be a polymer foam such as polyurethane foam.

[0017] Furthermore, such as Figure 2 As shown, the fiber mesh layer 31 has a square mesh shape and consists of at least three layers, arranged symmetrically with the middle layer as the plane of symmetry. This symmetrical structure ensures the stability and balance of the board under load and effectively prevents bending deformation.

[0018] Furthermore, such as Figure 2 and Figure 3 As shown, the composite protective layer 4 includes a moisture-proof layer 41, which is bonded to the outer surfaces of the upper panel 1 and the lower panel 2 respectively. It effectively blocks external moisture from entering and protects the internal structure. Its material can be a high-polymer waterproof membrane such as PVC film. A transparent wear-resistant layer 42 is bonded to the outer surface of the moisture-proof layer 41, which gives the panel surface excellent scratch resistance and wear resistance, and extends its service life. This wear-resistant layer is usually a polyurethane topcoat or fluorocarbon coating with excellent wear resistance.

[0019] Furthermore, such as Figure 2 and Figure 3As shown, the composite functional layer 5 includes a fireproof layer 51, which is bonded to the inner surfaces of the upper panel 1 and the lower panel 2 respectively. It plays a role in flame retardancy, heat insulation and improving safety level. It is often made of materials such as gypsum board, vermiculite board and flame retardant foam. A transition layer 52 is bonded to the inner side of the fireproof layer 51. The transition layer 52 ensures that the bonding between the layers is firm and can relieve stress. It can be composed of an adhesive layer, flexible foam or non-woven fabric.

[0020] Furthermore, such as Figure 2 and Figure 3 As shown, the inner side of the transition layer 52 is bonded with an antibacterial layer 521, which is bonded to the outer side of the interwoven fiber layer 3. It can effectively inhibit the growth of microorganisms and ensure the applicability of the board in environments with high hygiene requirements. It is usually a film or coating with added antibacterial agents such as silver ions, or made of materials with antibacterial properties.

[0021] Furthermore, such as Figure 2 and Figure 3 As shown, the interwoven fiber layer 3 has an edge seal 6 bonded to its four sides. The edge seal 6 and the interwoven fiber layer 3 form a closed reinforcing unit. The edge seal 6 serves the dual purpose of strengthening the edge strength, preventing delamination, and sealing the end face to prevent moisture and contaminants from entering from the edge. The edge seal 6 can be made of plastic profile, metal profile, or sealing strip.

[0022] Working principle: The core of the working principle of this composite panel lies in its multi-layer composite structure design. Through the synergistic effect of each functional layer, it achieves a balance between structural strength, environmental durability, and functional safety. Its structural strength mainly comes from the internal interlaced fiber layer 3, which is composed of multiple fiber mesh layers 31. The fiber filaments 311 in these mesh layers are arranged in a specific angle α (preferably 90 degrees) in the main extension direction, and the gaps between the layers are filled with filler 32. This design enables the fibers to effectively bear and disperse the stress and strain transmitted from the panel in multiple directions, which greatly improves the bending resistance, impact resistance and isotropic mechanical properties of the composite board. The multi-layer fiber mesh layer 31 is symmetrically arranged with the middle layer as the center, which further ensures the stability and balance of the structure under load and prevents warping deformation. The interlaced fiber layer 3 is sealed around the edges by the edge sealing body 6, forming a complete and strong reinforcing unit, which not only enhances the edge strength but also plays a sealing role. In terms of environmental protection and durability, the composite board has a composite protective layer 4 on the outside of the upper and lower panels 2. This protective layer typically includes a moisture-proof layer 41 and a transparent wear-resistant layer 42 from the inside out. The moisture-proof layer 41 can effectively block the intrusion of external moisture and water, protecting the internal interwoven fiber layer 3 and functional layer from moisture corrosion. The outer transparent wear-resistant layer 42 gives the board surface excellent wear resistance and scratch resistance, extending its service life. In terms of safety and hygiene, the composite board has a composite functional layer 5 on the inner side of the upper and lower panels 2. This functional layer is usually composed of a fireproof layer 51, a transition layer 52 and an antibacterial layer 521. The fireproof layer 51 plays a role in flame retardancy and heat insulation, the transition layer 52 ensures strong adhesion between the layers and relieves stress, and the innermost antibacterial layer 521 can inhibit the growth of microorganisms, thus ensuring the applicability of the composite board in environments with high hygiene requirements.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
