Description

Technical Field

[0001] This utility model relates to the field of carbon fiber sheets, and in particular to a structure of a carbon fiber sheet. Background Technology

[0002] Carbon fiber sheets are widely used in aerospace, wind turbine blades, sports lights and other fields due to their high strength, high modulus and lightweight properties. However, the surface of carbon fiber is easily worn away, and even ordinary sandpaper can easily grind off carbon powder. In addition, the surface of carbon fiber is brittle and has weak impact resistance, making it prone to breakage when subjected to lateral impact.

[0003] Currently, a Chinese patent application with authorization announcement number CN 206953717 U and authorization announcement date of February 2, 2018, proposes a novel carbon fiber plate structure. The carbon fiber plate body has a metal protective layer on both sides, and a cone-shaped polymer wear-resistant protrusion on both sides. The sides of the polymer wear-resistant protrusion taper inward to form an inner arc structure. The inner end of the polymer wear-resistant protrusion is set in the mounting groove on the surface of the carbon fiber plate body, the middle of the polymer wear-resistant protrusion passes through the metal protective layer, and the outer end of the polymer wear-resistant protrusion has a smooth spherical structure.

[0004] During use, the metal protective layer and polymer wear-resistant protrusions on the surface of the carbon fiber sheet provide protection.

[0005] Regarding the aforementioned technologies, placing metal directly on carbon fiber may cause electrochemical corrosion, especially in humid environments where electrochemical corrosion is more severe, seriously affecting the performance of carbon fiber sheets. Furthermore, the metal protective layer increases the weight of carbon fiber sheets, which is not conducive to the lightweighting of carbon fiber sheets. Utility Model Content

[0006] In order to improve the toughness of carbon fiber sheets, reduce the impact of the protective layer on the performance of carbon fiber sheets, and give full play to the advantages of carbon fiber sheets, this utility model provides a structure for carbon fiber sheets.

[0007] This utility model provides a structure for a carbon fiber sheet, employing the following technical solution:

[0008] A structure for a carbon fiber sheet includes a carbon fiber sheet, on the surface of which a solid wood veneer is fixedly disposed, and a transparent protective layer is disposed on the side of the solid wood veneer away from the carbon fiber sheet; an adhesive layer is disposed between the solid wood veneer and the carbon fiber sheet, the adhesive layer being used to fix the solid wood veneer to the surface of the carbon fiber sheet.

[0009] When using a metal protective layer to protect carbon fiber sheets, galvanic corrosion can occur when different conductors come into contact in an electrolyte (water vapor in the air, especially in humid environments), as both metal and carbon fiber are conductive materials with a significant potential difference. This damages the carbon fiber and affects the performance of the carbon fiber sheet. Furthermore, when the metal protective layer is fixed to the surface of the carbon fiber sheet, ordinary adhesives have low shear strength, resulting in an unreliable bond between the metal protective layer and the carbon fiber. Finally, the metal has a larger mass than the carbon fiber sheet, so using a metal protective layer to protect the carbon fiber sheet can negate the lightweight advantage of the carbon fiber sheet.

[0010] By adopting the above technical solutions, the fiber structure of wood has a certain elastic modulus, which can absorb small-energy impacts and disperse the impact energy in all directions. Therefore, using solid wood veneer to protect the surface of carbon fiber boards can reduce the probability of brittle fracture when the carbon fiber boards are subjected to impact. Solid wood veneer also has a certain strength, which can enhance the overall impact resistance of carbon fiber. When the board is subjected to external impact, solid wood veneer can share some of the impact force, reducing the degree of damage to carbon fiber. At the same time, the solid wood veneer attached to the surface of carbon fiber boards can also reduce wear on carbon fiber boards. Furthermore, wood is hygroscopic, and setting a transparent protective layer on the surface of solid wood veneer can isolate the solid wood veneer from water vapor in the air, reducing the probability of the solid wood veneer absorbing moisture. At the same time, the transparent protective layer can also protect the surface of solid wood veneer, reducing the probability of the solid wood veneer being scratched. The transparent protective layer can also show the texture of solid wood veneer, increasing the aesthetics of the board.

[0011] By adopting the above technical solution, the carbon fiber board and the solid wood veneer are bonded together using an adhesive layer, which can make the bonding between the solid wood veneer and the carbon fiber board more uniform and reliable, and significantly improve the bonding strength between the solid wood veneer and the carbon fiber board.

[0012] Optionally, the transparent protective layer is made of piano lacquer.

[0013] By adopting the above technical solutions, piano lacquer has excellent wear resistance, corrosion resistance, easy cleaning and high gloss. Applying piano lacquer to the outer surface of solid wood veneer for protective treatment can not only ensure that the natural texture of the solid wood veneer is clearly visible, but also significantly reduce the risk of the solid wood veneer being scratched and worn. In addition, the corrosion resistance of piano lacquer can also effectively improve the durability of the board.

[0014] Optionally, the transparent protective layer may also be a solid high-transparency resin.

[0015] By adopting the above technical solutions, solid high-transparency resin also has excellent wear resistance, corrosion resistance and high transparency. Using solid high-transparency resin as a protective layer on the outer surface of solid wood veneer can effectively reduce the risk of solid wood veneer being scratched and worn. Moreover, after the solid high-transparency resin is scratched, it can be repaired and cured with repair resin, which is convenient for maintenance.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] Solid wood veneer has good toughness and a certain elastic modulus. By applying solid wood veneer to the surface of carbon fiber board, it can act as a buffer when the board is impacted. Solid wood veneer can absorb part of the impact force on the board and disperse the impact force on the surface of carbon fiber board, reducing the risk of brittle fracture after the carbon fiber board is impacted. At the same time, solid wood veneer can also effectively reduce the probability of scratches caused by direct contact between objects and carbon fiber board.

[0018] Solid wood veneer is lighter than metal. Using solid wood veneer to protect the surface of carbon fiber sheets can effectively reduce the impact of the protective layer on the lightweight nature of the carbon fiber sheets, thus fully leveraging the advantages of lightweight carbon fiber sheets.

[0019] Applying a transparent protective layer to the surface of solid wood veneer can isolate the veneer from the external environment, reducing the probability of it absorbing moisture and becoming damp, while also reducing the likelihood of it being scratched. The transparent material also allows the wood grain of the veneer to be visible, enhancing its aesthetic appeal. Attached Figure Description

[0021] Explanation of reference numerals in the attached drawings: 100, carbon fiber sheet; 200, solid wood veneer; 300, transparent protective layer; 400, adhesive layer. Detailed Implementation

[0022] The following combination Figure 1 The present invention will be described in further detail below.

[0023] This utility model discloses a structure for a carbon fiber sheet. (Refer to...) Figure 1 A carbon fiber sheet structure mainly includes a carbon fiber sheet 100, a solid wood veneer 200 for protecting the carbon fiber sheet 100, an adhesive layer 400 for fixing the carbon fiber sheet 100 and the solid wood veneer 200, and a transparent protective layer 300 for protecting the solid wood veneer 200.

[0024] Reference Figure 1The transparent protective layer 300, solid wood veneer 200, adhesive layer 400, and carbon fiber board 100 are arranged sequentially from top to bottom. In this embodiment, the carbon fiber board 100 serves as the base layer, the solid wood veneer 200 serves as the first protective layer, and the transparent protective layer 300 serves as the second protective layer.

[0025] When fixing the first protective layer, firstly, an adhesive layer 400 is set on the side of the solid wood veneer 200 close to the carbon fiber plate 100. Secondly, the adhesive layer 400 is attached to the surface of the carbon fiber plate 100. Finally, the solid wood veneer 200 and the carbon fiber plate 100 are clamped together and fixed at one end for a period of time to allow the adhesive layer 400 to cure.

[0026] When treating the second protective layer, a transparent protective material is sprayed or brushed onto the surface of the solid wood veneer 200. After the transparent anti-slip material has cured, it is sanded and then cured and polished layer by layer repeatedly to form a transparent protective layer 300.

[0027] In this embodiment, the adhesive layer 400 is mainly composed of adhesive materials such as epoxy resin, polyurethane or nano glue; the solid wood veneer 200 is based on wood with clear texture and good toughness such as mahogany, walnut or sandalwood; the transparent protective layer 300 is made of piano lacquer or solid high-transparency resin, and the piano lacquer or solid high-transparency resin is applied to the surface of the solid wood veneer using conventional processing technology.

[0028] In other embodiments, the specific material of the transparent protective layer 300 can be flexibly adjusted according to actual process requirements, as long as it can effectively protect the solid wood veneer 200 and ensure that the wood grain of the solid wood veneer 200 can be clearly observed through the transparent protective layer 300.

[0029] The implementation principle of the structure of a carbon fiber plate in this embodiment of the present invention is as follows: a carbon fiber plate 100 is used as a substrate, a solid wood veneer 200 is sequentially arranged on the carbon fiber plate 100 as a first protective layer, and a transparent protective layer 300 is arranged on the solid wood veneer 200 as a second protective layer.

[0030] When the board is impacted, the solid wood veneer 200 absorbs part of the impact force and disperses the remaining impact force on the surface of the carbon fiber board 100, reducing the risk of brittle fracture of the carbon fiber board 100 after impact. The solid wood veneer 200 also has good toughness. By combining the solid wood veneer 200 with the carbon fiber board 100, the overall toughness of the board can be improved. The transparent protective layer 300 can play a role in preventing scratches and friction on the surface, while also isolating the solid wood veneer 200 from the external environment, reducing the probability of the solid wood veneer 200 absorbing water and moisture, thus protecting the solid wood veneer 200. The transparent material can also show the wood grain of the solid wood veneer 200, enhancing its aesthetics.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
