[0020] 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.

[0021] Please see Figures 1 to 2 This utility model provides a technical solution: a composite board with high impact resistance, comprising a base layer 1, a shock-absorbing core layer 2 fixedly connected to the top of the base layer 1, a multi-functional isolation layer 3 fixedly connected to the top of the shock-absorbing core layer 2, a high-strength support layer 4 fixedly connected to the top of the multi-functional isolation layer 3, a buffer energy-absorbing layer 5 fixedly connected to the top of the high-strength support layer 4, and a surface protective layer 6 fixedly connected to the top of the buffer energy-absorbing layer 5.

[0022] It should be noted that the bottom of the base layer 1 is equipped with anti-slip bumps. The anti-slip bumps at the bottom of the base layer 1 are designed to improve the stability of the composite board in practical applications. The anti-slip bumps can generate strong friction on the contact surface, thereby preventing the composite board from sliding or shifting during use. The anti-slip bumps can be designed in the form of circles, squares, cones, etc., according to different actual needs. The size, spacing, and height of the bumps can be adjusted according to the specific usage environment to ensure the maximum anti-slip effect.

[0023] The high-strength support layer 4 has a honeycomb structure, and the pore size of the honeycomb structure gradually decreases from top to bottom. The design of the honeycomb pore size gradually decreasing from top to bottom can effectively increase the strength and rigidity of the composite board. The design of the pore size gradually decreasing from top to bottom allows the material to gradually absorb and disperse energy according to the change in pore size when facing different levels of impact, thereby improving the impact resistance of the overall structure. The larger pore size in the upper layer can slow down the initial impact, while the smaller pore size in the lower layer can better support the load and increase the load-bearing capacity of the material.

[0024] The outer surface of the surface protective layer 6 is provided with a wear-resistant texture and coated with an impact-resistant coating. The wear-resistant texture helps to slow down the wear of the surface during long-term use, while the impact-resistant coating enhances the material surface's resistance to external impacts. The impact-resistant coating can be made of coatings with strong impact resistance, such as polyurethane and epoxy resin.

[0025] The buffer energy-absorbing layer 5 is composed of a soft layer 501, an elastic layer 502, and a hard layer 503, with the soft layer 501 at the top, the hard layer 503 at the bottom, and the elastic layer 502 between the soft layer 501 and the hard layer 503. The soft layer 501 is mainly used to withstand the initial deformation when subjected to external impact force and effectively disperses some of the impact energy through its softness. The elastic layer 502 mainly functions to elastically deform, absorb impact energy, and quickly restore its original shape. The hard layer 503 can provide strong support and compressive strength to prevent the buffer energy-absorbing layer 5 from undergoing irreversible deformation due to excessive impact force.

[0026] The soft layer 501, the elastic layer 502, and the rigid layer 503 are fixedly connected to each other by hot pressing.

[0027] The base layer 1, shock-absorbing core layer 2, multi-functional isolation layer 3, high-strength support layer 4, buffer energy-absorbing layer 5, and surface protective layer 6 are fixedly connected to each other by an adhesive, and the adhesive used is a waterproof adhesive.

[0028] In addition, the base layer 1 is made of carbon fiber composite material, which has good impact resistance and aging resistance, and can effectively support the upper structure.

[0029] The shock-absorbing core layer 2 is a polymer composite material that can effectively absorb external impact forces and reduce impact energy through its elastic properties.

[0030] The multifunctional isolation layer 3 is made of polyurethane foam, which can effectively block the influence of the external environment, such as temperature changes or sound transmission, and enhance the multifunctionality of the composite board.

[0031] The high-strength support layer 4 is made of honeycomb aluminum alloy, which has high strength and rigidity and can effectively support and transmit impact loads.

[0032] The soft layer 501 is made of rubber, providing initial impact absorption; the elastic layer 502 is made of elastic polymer, absorbing impact and quickly returning to its original shape; the rigid layer 503 is made of high-density polyethylene, which has stronger load-bearing and compressive strength, preventing deformation of the buffer energy-absorbing layer.

[0033] The working principle of the above embodiments is as follows:

[0034] The base layer 1 is made of carbon fiber composite material, which has high impact resistance, aging resistance and strength. Through its excellent mechanical properties, it provides strong support for the upper structure and ensures the overall structural stability of the composite board.

[0035] The shock-absorbing core layer 2 uses a high-molecular composite material, which has excellent elasticity and shock absorption properties. Through elastic deformation, this layer can effectively absorb and disperse some of the impact energy when it is impacted, thereby reducing the transmission of impact to subsequent layers.

[0036] The multi-functional isolation layer 3 is made of polyurethane foam, which has heat insulation, sound insulation and moisture-proof functions. Under different environmental conditions, it can effectively block the interference of external environmental changes on the performance of composite board, while providing additional shock absorption.

[0037] The high-strength support layer 4 is a honeycomb aluminum alloy structure. This layer has high strength, rigidity and excellent compressive strength. The geometry of the honeycomb structure can effectively disperse external impact force in different directions, enhancing the overall impact resistance of the composite panel. In addition, the gradually decreasing pore size of the honeycomb structure helps to cope with impacts of different intensities, and the smaller pore size of the lower layer can better support and disperse impact loads.

[0038] The buffer energy-absorbing layer 5 is composed of a soft layer 501, an elastic layer 502, and a hard layer 503. The soft layer 501 is made of rubber material, which can undergo initial deformation when subjected to external impact and effectively disperse some of the impact energy through its softness, thus mitigating the destructive impact on the material. The elastic layer 502 is made of elastic polymer, which mainly absorbs impact energy through elastic deformation and quickly returns to its original shape, further dispersing the impact force. The hard layer 503 is made of high-density polyethylene, which has strong compressive strength and can effectively prevent the buffer layer from undergoing irreversible deformation under high-intensity impact, thereby enhancing the overall structural stability of the buffer energy-absorbing layer 5.

[0039] The surface protective layer 6 adopts a wear-resistant texture and an impact-resistant coating design. The wear-resistant texture helps to slow down the performance degradation of the surface due to friction and wear during long-term use, while the impact-resistant coating effectively prevents damage to the surface of the composite board by enhancing the impact resistance of the surface.
