Description

Technical Field

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

[0002] With the urgent need for weight reduction and efficiency improvement in various industries, core requirements have been put forward for structural materials to be lighter, stronger and lower energy consumption. Traditional materials are difficult to meet the needs of lightweight and high performance at the same time, which has driven the development of carbon fiber composite materials.

[0003] However, in the existing technology, most carbon fiber boards adopt a uniform mesh hollow or a single honeycomb structure. In actual use, under the impact or bending of external forces, some stress areas are structurally weak and prone to breakage, and non-stress areas have material waste due to excess fiber performance. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing carbon fiber sheets mostly adopt uniform mesh hollow or single honeycomb structure, which in actual use, under the action of external force impact or bending, some stress areas are structurally weak and prone to breakage, and non-stress areas cause material waste due to excess fiber performance. Therefore, a lightweight carbon fiber sheet is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight carbon fiber plate, comprising a surface carbon fiber plate, a core plate, and a bottom carbon fiber plate, wherein the surface carbon fiber plate is fixedly connected to the top surface of the core plate, and the bottom carbon fiber plate is fixedly connected to the bottom surface of the core plate. The core plate comprises an outer frame plate, reinforcing ribs, and a honeycomb plate, wherein the reinforcing ribs are fixedly connected to the inner wall of the outer frame plate, and the honeycomb plate is fixedly connected to the gap between the reinforcing ribs and the inner side wall of the outer frame plate.

[0006] Preferably, the surface carbon fiber plate includes a main body layer, a composite reinforcing layer and an adhesive layer, wherein the composite reinforcing layer is fixedly connected to the outer edge wall of the main body layer.

[0007] Preferably, the adhesive layer is disposed on the interface between the main board layer and the core board.

[0008] Preferably, the outer walls on both sides of the outer frame plate are provided with multiple slots and blocks.

[0009] Preferably, the slots on one side of the outer frame plate are correspondingly set with the blocks on the other side, and the two outer frame plates are spliced ​​together by the slots and blocks.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by having reinforcing ribs radially distributed along the inner wall of the outer frame plate and integrally formed with the outer frame plate, the load transmitted by the surface / bottom carbon fiber plate can be distributed to the entire core plate, significantly improving the plate's resistance to buckling. In conjunction with the honeycomb plate filling the gap between the reinforcing ribs and the inner wall of the outer frame plate, while ensuring lightweighting, the honeycomb unit's distributed support effect prevents the surface / bottom carbon fiber plate from deforming due to excessive local stress.

[0012] 2. In this utility model, the main body layer bears the main load, and the outer wall composite reinforcement layer set at the edge of the main body layer is made of carbon fiber and basalt fiber. By utilizing its high impact resistance, the shear strength of the plate edge is improved, which solves the problem of easy cracking at the edge of the traditional plate. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figure 1 - Figure 3As shown, this utility model provides a lightweight carbon fiber plate, including a surface carbon fiber plate 1, a core plate 2, and a bottom carbon fiber plate 3. The surface carbon fiber plate 1 is fixedly connected to the top surface of the core plate 2, and the bottom carbon fiber plate 3 is fixedly connected to the bottom surface of the core plate 2. The core plate 2 includes an outer frame plate 21, reinforcing ribs 22, and a honeycomb plate 23. The reinforcing ribs 22 are fixedly connected to the inner wall of the outer frame plate 21, and the honeycomb plate 23 is fixedly connected to the gap between the reinforcing ribs 22 and the inner side wall of the outer frame plate 21.

[0020] The specific setup and function of this embodiment will be described in detail below. The surface carbon fiber plate 1 and the bottom carbon fiber plate 3 serve as the main load-bearing layers of the plate, and can directly withstand external tensile, compressive, and shear loads. Their high strength characteristics ensure the overall load-bearing capacity of the plate. The outer frame plate 21 forms the outer peripheral support frame of the plate, using a density of 0.08 g / cm³. 3 The core board 2 is made of PMI foam with a thickness of 5-10mm, which is consistent with the core board 2. This ensures the structural stability of the board edge and provides an installation reference for the reinforcing ribs 22 and the honeycomb panel 23. The reinforcing ribs 22 are radially distributed along the inner wall of the outer frame 21 and are integrally formed with the outer frame 21. This can disperse the load transmitted by the surface / bottom carbon fiber board to the entire core board, significantly improving the board's buckling resistance. The honeycomb panel 23 fills the gap between the reinforcing ribs 22 and the inner wall of the outer frame 21. While reducing weight, the honeycomb unit disperses the support and prevents the surface / bottom carbon fiber board from deforming due to excessive local stress.

[0021] Example 2: Figure 1 - Figure 3 As shown, the surface carbon fiber plate 1 includes a main plate layer 11, a composite reinforcing layer 12, and an adhesive layer 13. The composite reinforcing layer 12 is fixedly connected to the outer edge of the main plate layer 11. The adhesive layer 13 is disposed on the connection surface between the main plate layer 11 and the core plate 2. Multiple slots 24 and blocks 25 are provided on both sides of the outer wall of the outer frame plate 21. The slots 24 on one side of the outer frame plate 21 are correspondingly disposed with the blocks 25 on the other side. The two outer frame plates 21 are spliced ​​together through the slots 24 and blocks 25.

[0022] The overall effect of this embodiment is as follows: the main body layer 11, which is the main body of the surface carbon fiber plate, bears the main load. The outer wall composite reinforcement layer 12, which is set at the edge of the main body layer 11, is made of carbon fiber and basalt fiber. It utilizes the high impact resistance to improve the shear strength of the plate edge and solves the problem of easy cracking of the traditional plate edge. The adhesive layer 13 uses a modified epoxy film, which is uniformly coated on the contact surface between the main body layer 11 and the core plate 2 to improve the peel strength between the surface carbon fiber plate 1 and the core plate 2 and avoid delamination failure. The slots 24 and blocks 25 on both sides of the outer wall of the outer frame plate 21 are designed with concave and convex matching. The height of the blocks 25 is adapted to the slots 24, which can realize the rapid splicing of multiple outer frame plates 21 without additional connectors. The splicing design of the slots 24 and blocks 25 improves the modular assembly efficiency of the plate and can splice plates of different sizes according to the needs. The strength of the splice is consistent with the overall structure.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
