It combines the excellent properties of carbon fiber with the functional and aesthetic requirements of interior trim, providing a high-performance, lightweight, and uniquely textured interior solution for modern vehicles.

[0003] In the modern automotive industry, as consumers' demands for vehicle comfort, safety, and personalization continue to increase, interior design and material selection have become key areas of focus for automakers.

[0004] Currently, some automotive interior materials include plastics, metals, wood, and leather. While plastics have certain plasticity and cost advantages, their strength is relatively low, and they may release harmful gases in high-temperature environments. Although metal interior parts have high strength, their density is high, which is not conducive to the lightweighting of automobiles. While wood and leather can provide a good texture, they are limited in resources, complex to process, expensive, and difficult to maintain.

[0005] Therefore, carbon fiber interior trim parts for automobiles are proposed. Utility Model Content

Although plastic has certain plasticity and cost advantages, its strength is relatively low and it may release harmful gases in high-temperature environments. Although metal interior trim has high strength, its density is high, which is not conducive to the lightweighting of automobiles. Although wood and leather can provide a good texture, they have problems such as limited resources, complex processing, high cost and difficulty in maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber interior trim for automobiles, comprising an interior trim body, the interior trim body including a carbon fiber pattern, connecting pieces, a first reinforcing filament, a second reinforcing filament, a prepreg, and a protective layer, the prepreg including a first carbon fiber prepreg, a second carbon fiber prepreg, a third carbon fiber prepreg, and a fourth carbon fiber prepreg, the carbon fiber pattern being embedded inside the first carbon fiber prepreg, the bottom of the first carbon fiber prepreg contacting the top of the second carbon fiber prepreg, and the bottom of the carbon fiber pattern contacting the top of the second carbon fiber prepreg.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] The automotive carbon fiber interior trim includes an interior trim body 1, which includes a carbon fiber pattern 2, a connecting piece 3, a first reinforcing filament 4, a second reinforcing filament 5, a prepreg 6, and a protective layer 7. The prepreg 6 includes a first carbon fiber prepreg 601, a second carbon fiber prepreg 602, a third carbon fiber prepreg 603, and a fourth prepreg 604. The carbon fiber pattern 2 is embedded inside the first carbon fiber prepreg 601, and the bottom of the first carbon fiber prepreg 601 contacts the top of the second carbon fiber prepreg 602. The bottom of the carbon fiber pattern 2 also contacts the top of the second carbon fiber prepreg 602.

[0026] Specifically, such as Figure 2As shown, the top of the connecting piece 3 contacts the bottom of the carbon fiber pattern 2. There are several connecting pieces 3. The connecting pieces 3 are located between the opposite sides of the first carbon fiber prepreg 601 and the second carbon fiber prepreg 602. The bottom of the connecting piece 3 contacts the top of the second carbon fiber prepreg 602.

[0027] Specifically, such as Figure 3 As shown, the first reinforcing wire 4 is disposed at the bottom of the second carbon fiber prepreg 602, and the first reinforcing wire 4 is vertically distributed at the bottom of the second carbon fiber prepreg 602.

[0028] Specifically, such as Figure 4 As shown, the second reinforcing filament 5 is disposed at the bottom of the third carbon fiber prepreg 603. The second reinforcing filament 5 is obliquely distributed at the bottom of the third carbon fiber prepreg 603. The first reinforcing filament 4 and the second reinforcing filament 5 are both woven from polyacrylonitrile-based carbon fiber filaments.

[0029] Specifically, such as Figure 1 As shown, the first carbon fiber prepreg 601, the second carbon fiber prepreg 602, the third carbon fiber prepreg 603 and the fourth prepreg 604 are all formed by hot pressing.

[0030] In this embodiment: the carbon fiber pattern 2, by being embedded between the first carbon fiber prepreg 601, increases the strength of the interior trim body 1. The strength of the interior trim body 1 is further increased by the vertically distributed first reinforcing wire 4 and the obliquely distributed second reinforcing wire 5. The first carbon fiber prepreg 601, the second carbon fiber prepreg 602, the third carbon fiber prepreg 603, and the fourth prepreg 604 made of carbon fiber can reduce weight and lower the overall weight of the interior trim body 1. The first carbon fiber prepreg 601, the second carbon fiber prepreg 602, the third carbon fiber prepreg 603, and the fourth prepreg 604, which are impregnated with resin, are tightly bonded by heating, melting, and high-pressure pressing in an external autoclave to form an integral structure, ensuring uniform stress transmission between layers and giving the interior trim body 1 good mechanical properties.

[0031] Specifically, such as Figure 5 As shown, the protective layer 7 includes a stain-resistant layer 701 and a wear-resistant layer 702. The wear-resistant layer 702 is uniformly coated on the surface of the interior trim body 1, and the stain-resistant layer 701 is uniformly coated on the surface of the wear-resistant layer 702.

[0032] Specifically, such as Figure 5 As shown, the wear-resistant layer 702 is made of polyurethane coating, and the stain-resistant layer 701 is made of nano-fluorocarbon coating.

[0033] In this embodiment: the wear-resistant layer 702 is uniformly coated on the surface of the interior part body 1. Its material is polyurethane coating. With the good wear resistance of polyurethane, it effectively reduces the scratches and wear caused by friction on the surface of the interior part body 1 during daily use, and extends the service life of the interior part. The stain-resistant layer 701 is uniformly coated on the surface of the wear-resistant layer 702. The stain-resistant performance of the nano fluorocarbon coating can prevent stains, fingerprints, oil stains and other substances from adhering to the surface of the interior part, keeping the interior part clean and beautiful, and making the interior part easy to clean and maintain.

[0034] Working principle: The carbon fiber pattern 2 is embedded inside the first carbon fiber prepreg 601, which not only serves a decorative purpose but also increases the compressive strength and toughness of the interior trim body 1 to a certain extent. The connecting piece 3 is located between the first carbon fiber prepreg 601 and the second carbon fiber prepreg 602 on opposite sides, enhancing the connection strength between the carbon fiber pattern 2 and the first carbon fiber prepreg 601, the second carbon fiber prepreg 602, the third carbon fiber prepreg 603, and the fourth prepreg 604, making the entire interior trim body 1 more stable. When subjected to external forces, it can share the force and avoid delamination between layers. The first reinforcing wire 4 is vertically distributed at the bottom of the second carbon fiber prepreg 602. The first reinforcing filament 601, the second reinforcing filament 602, the third reinforcing filament 603, and the fourth reinforcing filament 604 are mainly responsible for the stress in the vertical direction, enhancing the tensile and compressive strength of the interior component body 1 in this direction. The second reinforcing filament 5 is obliquely distributed at the bottom of the third carbon fiber prepreg 603, and works in conjunction with the first reinforcing filament 4 to effectively disperse and bear external forces from different directions, further improving the overall strength and stability of the interior component body 1. These reinforcing filaments are all woven from polyacrylonitrile-based carbon fiber filaments, making full use of the high strength characteristics of carbon fiber. The first carbon fiber prepreg 601, the second carbon fiber prepreg 602, the third carbon fiber prepreg 603, and the fourth prepreg 604 are bonded together by an external autoclave. Fiber prepreg 603 and fourth prepreg 604 are tightly bonded together through a heating, melting, and high-pressure pressing process to form a single integral structure. This ensures uniform stress transfer between layers, giving the interior trim good mechanical properties and reducing weight. A wear-resistant layer 702, made of polyurethane coating, is uniformly coated on the surface of the interior trim body 1. The excellent wear resistance of polyurethane effectively reduces scratches and wear on the surface of the interior trim body 1 caused by friction during daily use, extending the service life of the interior trim. A stain-resistant layer 701 of nano-fluorocarbon coating is uniformly coated on the surface of the wear-resistant layer 702. The stain-resistant properties of the nano-fluorocarbon coating prevent stains, fingerprints, and oil stains from adhering to the surface of the interior trim, keeping it clean and aesthetically pleasing. In the interior environment, the stain-resistant layer 701 can effectively resist dust, beverage spills, or traces left by people touching the interior, making the interior parts body 1 easy to clean and maintain. This avoids the problems of existing automotive interior materials such as plastic, metal, wood, and leather. Although plastic has certain plasticity and cost advantages, its strength is relatively low and it may release harmful gases in high-temperature environments. Although metal interior parts have high strength, their density is high, which is not conducive to the lightweighting of automobiles. Although wood and leather can provide a good texture, they have problems such as limited resources, complex processing, high cost, and difficulty in maintenance. It should be noted that carbon fiber prepreg is a material in which carbon fiber is pre-impregnated with resin and treated in a certain way, which will not be elaborated here.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
