[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.
[0039] The embodiment of the present application provides a decorative member 10. Please refer to Figure 1 and Figure 2, comprising a fiber layer 1 and a metal particle layer 2. The metal particle layer 2 is arranged on at least one side of the fiber layer 1. The metal particle layer 2 can serve as a load-bearing structure to disperse and transfer stress when subjected to force, thereby improving the overall toughness of the decorative part 10. The combination of the metal particle layer 2 and the fiber layer 1 can form a more complex mechanical structure, so that the decorative part 10 exhibits better strength and stiffness performance. The fiber layer 1 itself has good high temperature resistance, and the addition of the metal particle layer 2 can further improve the performance of the decorative part 10 in a high temperature environment and improve the stability of the decorative part 10 at high temperatures. In addition, compared with the single fiber layer 1, the addition of the metal particle layer 2 can provide better thermal conductivity, so that the decorative part 10 has better thermal conductivity. That is, the decorative part 10 provided in the embodiment of the present application has good strength and toughness, good high temperature resistance and thermal conductivity, and is applicable to a wider range of scenarios.
[0040] In addition, the decorative part 10 has a fiber layer 1 with a fiber texture, and a metal particle layer 2 with a metallic texture and luster, so that the decorative part 10 can have both metallic texture and luster and fiber texture, thereby enhancing the visual effect of the decorative part 10.
[0041] It is understandable that in the decorative element 10 provided in the embodiment of the present application, the metal particle layer 2 ( Figure 1 ), metal particle layers 2 may also be provided on both sides of the fiber layer 1 ( Figure 2 In order to reduce the cost, it is preferred to provide a metal particle layer 2 on one side of the fiber layer 1 .
[0042] In some embodiments, the thickness of the fiber layer 1 is 0.5 mm to 3 mm. A thicker fiber layer 1 increases its strength, which can improve the mechanical properties of the decorative piece 10 and enhance the visual effect of the fiber texture. However, a thicker fiber layer 1 also increases its weight, affecting the overall weight of the decorative piece 10 and hindering lightweighting. Furthermore, an increase in the thickness of the fiber layer 1 also increases costs. To balance high mechanical performance and visual effects with lightweighting and cost reduction, the thickness of the fiber layer 1 is controlled within the range of 0.5 mm to 3 mm.
[0043] Illustratively, the thickness of the fiber layer 1 may be 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm or 3 mm.
[0044] In some embodiments, the thickness of the metal particle layer 2 is 0.1 mm - 1.0 mm. The metal particle layer 2 can endow the decorative member 10 with a metallic texture and luster, enhancing the visual effect of the decorative member 10. Similar to the fiber layer 1, an increase in the thickness of the metal particle layer 2 can also improve the mechanical properties and visual effect of the decorative member 10. However, when the thickness of the metal particle layer 2 reaches a certain level, it can no longer further improve the mechanical properties and visual effect of the decorative member 10, but instead will cause an increase in weight and cost. Therefore, in order to ensure the mechanical properties and visual effect of the metal particle layer 2 and achieve lightweight and cost reduction, the embodiments of the present application control the thickness of the metal particle layer 2 within the range of 0.1 mm - 1.0 mm.
[0045] Exemplarily, the thickness of the metal particle layer 2 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1.0 mm.
[0046] In some embodiments, the fiber layer 1 includes a chopped carbon fiber layer. The chopped carbon fiber layer includes chopped carbon fibers with a length of 10 mm - 30 mm. The chopped carbon fibers have a high specific strength and specific modulus, and the chopped carbon fibers also have excellent high-temperature resistance and corrosion resistance, enabling the chopped carbon fiber layer to improve the structural strength and overall performance while ensuring lightweight. In addition, by setting the fiber layer 1 to include a chopped fiber layer, compared with the woven carbon fiber layer in the related art, the preparation difficulty can be reduced, the preparation process can be simplified, which helps to improve the preparation efficiency and reduce the preparation cost.
[0047] The chopped carbon fibers with a length of 10 mm - 30 mm are convenient for processing, easy to control and handle. When the length of the chopped carbon fibers is too large, the chopped carbon fibers are prone to breakage and loss during the processing. In addition, when the length of the chopped carbon fibers is within the range of 10 mm - 30 mm, they also have good strength and modulus, ensuring the mechanical properties of the chopped carbon fiber layer. Therefore, the embodiments of the present application can have better processing performance and mechanical properties, reduce the preparation difficulty of the chopped carbon fiber layer, and improve the mechanical properties of the chopped carbon fiber layer by controlling the length of the chopped carbon fibers in the chopped carbon fiber layer within the range of 10 mm - 30 mm.
[0048] Exemplarily, the length of the chopped carbon fibers can be 10 mm, 15 mm, 20 mm, 25 mm or 30 mm.
[0049] Among them, the types of the chopped carbon fibers include at least one of T300, T700, T800, T1000, T1100 and MJ60.
[0050] In some embodiments, the metal particle layer 2 includes a copper particle layer. The copper particle layer contains copper particles with a particle size of 10 mesh - 100 mesh. The copper particles can endow the decorative piece 10 with better metallic texture and luster, enhancing the visual effect, and can present rich color effects through different processing techniques. The processing of copper particles is relatively simple and the cost is relatively low. Copper particles of different particle sizes and different shapes can be simultaneously used in the copper particle layer, thereby increasing the visual hierarchy.
[0051] Exemplarily, in the embodiments of the present application, the copper particles can be processed using CNC scraps or recycled materials, thereby reducing costs. The copper particles can be at least one of red copper particles, brass particles, purple copper particles, bronze particles, and copper alloy particles.
[0052] In some embodiments, in the copper particle layer, the spacing between adjacent copper particles is 0.1 mm - 30 mm. The smaller the spacing between adjacent copper particles, the closer the arrangement, and the higher the mechanical strength of the formed copper particle layer. Conversely, the larger the spacing between adjacent copper particles, the sparser the arrangement, which will affect the mechanical strength of the copper particle layer. In addition, a tight arrangement can make the copper particle layer create a smooth and delicate texture, while a sparse arrangement can make the copper particle layer present a rough and natural visual effect.
[0053] In the actual application process, the spacing between adjacent copper particles in the copper particle layer can be set according to the desired visual effect. When the spacing between adjacent copper particles is within the range of 0.1 mm - 30 mm, good mechanical strength and visual effect can be ensured.
[0054] Exemplarily, the spacing between adjacent copper particles can be 0.1 mm, 0.5 mm, 2 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 30 mm.
[0055] In some embodiments, please refer to Figure 3 and Figure 4 , the decorative piece 10 further includes a protective layer 3. Among them, the protective layer 3 is disposed on the side of the metal particle layer 2 facing away from the fiber layer 1. Setting the protective layer 3 on the side of the metal particle layer 2 facing away from the fiber layer 1 can effectively isolate the metal particle layer 2 from direct contact with the external environment, reducing the risk of oxidation and corrosion, and the protective layer 3 can provide a physical barrier to reduce damage caused by mechanical forces such as scratching and impact, effectively preventing scratches and abrasions. In addition, the protective layer 3 can also improve the appearance texture of the decorative piece 10 and maintain the visual effect of the decorative piece 10.
[0056] In some embodiments, the protective layer 3 includes a transparent protective layer or a translucent protective layer. The transparent protective layer or the translucent protective layer can not only effectively protect the metal particle layer 2, but also maintain the color and texture of the metal particle layer 2 and the fiber layer 1, and endow the decorative member 10 with a more crystal-clear visual effect, thereby enhancing the overall aesthetics. Moreover, the transparent protective layer or the translucent protective layer also has the functions of anti-ultraviolet and heat insulation, further improving the protection effect on the metal particle layer 2 and the fiber layer 1.
[0057] Exemplarily, the protective layer 3 can be an epoxy resin layer. That is, the protective layer 3 is directly injection-molded from transparent epoxy resin. The epoxy resin layer has excellent physical and mechanical properties and electrical insulation properties, good adhesiveness, as well as excellent corrosion resistance and protection properties. Using the epoxy resin layer as the protective layer 3 can provide an effective protection function while highlighting the patterns, colors, and textures of the metal particle layer 2 and the fiber layer 1.
[0058] In some embodiments, please refer to Figure 4 , the protective layer 3 includes a first protective layer 31 and a second protective layer 32. Among them, the first protective layer 31 is disposed on the side of the metal particle layer 2 facing away from the fiber layer 1, and the second protective layer 32 is disposed on the side of the first protective layer 31 facing away from the metal particle layer 2. The first protective layer 31 is in direct contact with the metal particle layer 2, and can fill the holes on the surface of the metal particle layer 2, thereby improving the adhesion to the second protective layer 32. In addition, by providing the first protective layer 31 and the second protective layer 32, a double barrier can be provided to more effectively achieve the effect of isolating external oxygen and corrosive gases, and improve the protection effect. And different materials can be selected for the first protective layer 31 and the second protective layer 32 to achieve the complementary advantages of the two. For example, the first protective layer 31 is used to achieve chemical protection such as corrosion resistance and oxidation resistance, while the second protective layer 32 is used to achieve physical protection such as scratch resistance and impact resistance.
[0059] In some embodiments, the thickness of the first protective layer 31 is 0.2 mm - 3 mm. If the thickness of the first protective layer 31 is too large, it is easy to cause surface defects such as sagging and blistering, and it is easy to cause a decrease in flexibility and impact resistance. An increase in the thickness of the first protective layer 31 will also lead to an increase in material costs. When the thickness of the first protective layer 31 is too small, it may not be able to fully cover the defects on the surface of the metal particle layer 2, reducing its adhesion and protection performance to the metal particle layer 2.
[0060] Exemplarily, the thickness of the first protective layer 31 is 0.2 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.
[0061] In some embodiments, the thickness of the second protective layer 32 is 0.2 mm to 3 mm. Similar to the first protective layer 31, if the second protective layer 32 is too thick, it is also prone to surface defects, high cost, and reduced hardness. If the second protective layer 32 is too thin, it is likely to lead to insufficient covering power, poor protection effect, and shortened service life.
[0062] Illustratively, the thickness of the second protective layer 32 is 0.2 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm.
[0063] The first protective layer 31 may be a primer layer, and the second protective layer 32 may be a topcoat layer. The primer layer can fill minor surface defects on the metal particle layer 2, providing a smoother base for the topcoat layer. The primer layer can improve the adhesion of the topcoat layer, reducing the risk of peeling. The primer layer can also provide corrosion resistance and wear resistance. The topcoat layer can impart visual effects such as color, gloss, and texture, protect the primer layer, and further enhance protective capabilities.
[0064] For example, the primer layer can be made of polyurethane or epoxy paint, which can provide excellent mechanical properties and adhesion, and provide good protection. The topcoat layer can be made of polyurethane paint, which can provide a better visual effect on the surface of the decorative part 10 while ensuring protection and adhesion.
[0065] In some embodiments, see Figure 5 The decorative member 10 also includes a fixing member 4. The fixing member 4 is fixedly connected to the fiber layer 1 and is positioned on the side of the fiber layer 1 facing away from the metal particle layer 2. The fixing member 4 secures the decorative member 10 in a predetermined position, providing both support and fixation. By positioning the fixing member on the side of the fiber layer 1 facing away from the metal particle layer 2, the decorative member 10 can be installed with the side facing the metal particle layer 2 facing outward, ensuring both decorative effect and performance.
[0066] For example, the fixing member 4 can be a buckle or a stud. In actual application, a suitable setting form of the fixing member 4 can be selected according to the specific application scenario.
[0067] In some embodiments, the fiber layer 1 and the metal particle layer 2 are integrally formed. By integrally forming the fiber layer 1 and the metal particle layer 2, production efficiency can be improved, production costs can be reduced, and the fiber layer 1 and the metal particle layer 2 have a high bonding strength, thereby ensuring visual effects while improving structural strength.
[0068] Exemplarily, the fiber layer 1 includes chopped carbon fibers, and the metal particle layer 2 includes copper particles. The chopped carbon fibers and copper particles are cured by resin to form an integrally formed fiber layer 1 and metal particle layer 2.
