Description

Technical Field

[0001] This utility model relates to the field of carbon fiber composite material technology, and in particular to a carbon fiber composite aluminum single plate. Background Technology

[0002] Aluminum single-layer panels refer to building decoration materials that have undergone chromating and other treatments, followed by fluorocarbon spraying technology. Due to their good processability and strong decorative properties, aluminum single-layer panels are widely used in the field of building curtain walls. However, the existing use of aluminum single-layer panels has at least the following drawbacks: 1. Existing pure aluminum single-layer panels need to be thickened to meet wind pressure resistance requirements, which can easily increase building load and installation costs. If the thickness is reduced, deformation is likely to occur. 2. The surface of existing traditional aluminum single-layer panels relies solely on fluorocarbon coating for corrosion protection. Long-term outdoor use can easily lead to coating aging and oxidation of the aluminum substrate. Therefore, we have launched a new carbon fiber composite aluminum single-layer panel. Utility Model Content

[0003] The main objective of this invention is to provide a carbon fiber composite aluminum single-layer plate, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A carbon fiber composite aluminum panel includes a functional backing layer, an aluminum panel base layer fixedly connected to the upper end of the functional backing layer, an interface reinforcement layer fixedly connected to the upper end of the aluminum panel base layer, a carbon fiber reinforced composite layer fixedly connected to the upper end of the interface reinforcement layer, and a decorative outer layer fixedly connected to the upper end of the carbon fiber reinforced composite layer. The decorative outer layer includes a fluorocarbon resin composite coating, an anti-corrosion layer is fixedly connected to the upper end of the fluorocarbon resin composite coating, a first wear-resistant layer is fixedly connected to the outer surface of the fluorocarbon resin composite coating, and the fluorocarbon resin composite coating is fixedly connected to the carbon fiber reinforced composite layer.

[0005] Preferably, the functional backing layer includes a phenolic resin composite layer, a thick polyimide film is fixedly connected to the upper end of the phenolic resin composite layer, a magnesium hydroxide flame retardant layer is fixedly connected to the lower end of the phenolic resin composite layer, a second wear-resistant layer is fixedly connected to the outer surface of the phenolic resin composite layer, and the phenolic resin composite layer is fixedly connected to the aluminum single-panel base layer.

[0006] By adopting the above technical solution, the nano-aerogel of the backing layer works synergistically with the flame retardant to achieve both heat insulation and flame retardant functions, eliminating the need for additional heat insulation and fireproofing layers.

[0007] Preferably, the interface enhancement layer includes a support layer, a titanium alloy microneedle array layer is fixedly connected to the upper end of the support layer, a connecting layer is fixedly connected to the upper end of the titanium alloy microneedle array layer, and modified epoxy resin adhesive is fixedly connected to both the upper and lower ends of the support layer, the titanium alloy microneedle array layer and the connecting layer, and the support layer is fixedly connected to the aluminum single-panel base layer.

[0008] By adopting the above technical solution: titanium alloy microneedles form mechanical interlocking, combined with the chemical bonding of adhesives to improve interfacial shear strength; the carbon fiber reinforced composite layer is connected to the aluminum single plate through the titanium alloy microneedles of the interfacial reinforcement layer, thus avoiding brittle fracture of carbon fiber.

[0009] Preferably, the modified epoxy resin adhesive is adhered and fixedly connected to the carbon fiber reinforced composite layer.

[0010] Preferably, the modified epoxy resin adhesive at the bottom is adhered and fixedly connected to the aluminum single-panel base layer.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a carbon fiber reinforced composite layer, which uses 5052-H32 aluminum alloy, both strength and processability are considered. At the same time, the density of carbon fiber on the aluminum single panel base is much lower than that of aluminum. After the composite is completed, the overall density is reduced, the weight per unit area is reduced, and the building load is significantly reduced. 2. By setting a functional backing layer and coating the surface of the functional backing layer with a polyimide film, the water vapor transmission rate is reduced, and the aluminum substrate is prevented from corroding in humid environments. A fluorocarbon resin and nano titanium dioxide composite coating is used on the decorative outer layer to further protect the entire carbon fiber composite aluminum panel from corrosion.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-5 This utility model provides a technical solution: A carbon fiber composite aluminum single panel includes a functional backing layer 1, an aluminum single panel base layer 2 fixedly connected to the upper end of the functional backing layer 1, an interface reinforcement layer 3 fixedly connected to the upper end of the aluminum single panel base layer 2, a carbon fiber reinforced composite layer 4 fixedly connected to the upper end of the interface reinforcement layer 3, and a decorative outer layer 5 fixedly connected to the upper end of the carbon fiber reinforced composite layer 4. In this embodiment, the decorative outer layer 5 includes a fluorocarbon resin composite coating 51, with an anti-corrosion layer 52 fixedly connected to the upper end of the fluorocarbon resin composite coating 51, and a first wear-resistant layer 53 fixedly connected to the outer surface of the fluorocarbon resin composite coating 51. The fluorocarbon resin composite coating 51 is fixedly connected to the carbon fiber reinforced composite layer 4. The functional backing layer 1 includes a phenolic resin composite layer 11, with a thick polyimide film 12 fixedly connected to the upper end of the phenolic resin composite layer 11, a magnesium hydroxide flame retardant layer 13 fixedly connected to the lower end of the phenolic resin composite layer 11, and a second wear-resistant layer 14 fixedly connected to the outer surface of the phenolic resin composite layer 11. The phenolic resin composite layer 11 is fixedly connected to the aluminum single-panel base layer 2.

[0018] The above scheme provides corrosion protection for the decorative outer layer 5 during its use by using a fluorocarbon resin composite coating 51 and an anti-corrosion layer 52, and by using nano-aerogel or phenolic resin composite foam, which improves the thermal insulation performance of the entire aluminum panel compared to traditional aluminum panels. The thick polyimide film 12 provides corrosion protection for the functional backing layer 1 during its use.

[0019] In this embodiment, the interface reinforcement layer 3 includes a support layer 31, a titanium alloy microneedle array layer 32 is fixedly connected to the upper end of the support layer 31, a connecting layer 33 is fixedly connected to the upper end of the titanium alloy microneedle array layer 32, and a modified epoxy resin adhesive 34 is fixedly connected to both the upper and lower ends of the support layer 31, the titanium alloy microneedle array layer 32, and the connecting layer 33. The support layer 31 is fixedly connected to the aluminum single-panel base layer 2; the modified epoxy resin adhesive 34 is adhered and fixedly connected to the carbon fiber reinforced composite layer 4; and the lowest modified epoxy resin adhesive 34 is adhered and fixedly connected to the aluminum single-panel base layer 2.

[0020] The above scheme involves: first, sandblasting the surface of the aluminum single-panel base layer 2; then, inserting titanium alloy microneedles through laser drilling; and finally, coating with modified epoxy resin adhesive 34. The titanium alloy microneedles form a mechanical interlock, which, combined with the chemical bonding of the adhesive, enhances the interfacial shear strength.

[0021] It should be noted that this utility model is a carbon fiber composite aluminum single panel. During use, a functional backing layer 1 is provided, and a polyimide film is coated on the surface of the backing layer 1 to reduce water vapor permeability and prevent corrosion of the aluminum substrate in humid environments. A fluorocarbon resin and nano-titanium dioxide composite coating is applied to the decorative outer layer 5 to further protect the entire carbon fiber composite aluminum single panel from corrosion. A carbon fiber reinforced composite layer 4, made of 5052-H32 aluminum alloy, is also provided to balance strength and durability. In addition to improving workability, the carbon fiber density on the aluminum single-panel base layer 2 is much lower than that of aluminum, resulting in a lower overall density and lighter weight per unit area after composite, which significantly reduces the building load. The surface of the aluminum single-panel base layer 2 is sandblasted, and then titanium alloy micro needles are implanted by laser drilling. Then, modified epoxy resin adhesive 34 is applied. The titanium alloy micro needles form a mechanical interlock, which, combined with the chemical bonding of the adhesive, improves the interfacial shear strength. In addition to sandblasting, the aluminum single-panel base layer 2 is subjected to chromate passivation treatment to further improve the bonding with the interfacial reinforcement layer 3, while also enhancing the corrosion resistance of the aluminum substrate itself.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
