Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber materials, in particular to a sandwich type carbon fiber notebook computer shell. Background Art

[0002] Since carbon fiber composite materials have excellent properties such as light weight, high strength, corrosion resistance, and impact resistance, some manufacturers are currently applying carbon fiber composite materials to the production and manufacturing of laptop computer shells to meet people's pursuit of thin and light laptop computer shells. In the production process, multi-layer carbon fiber cloth (fiber length greater than 20mm) is generally used with resin and curing agent, and is integrally formed in a mold after heat and pressure. The above method has greatly improved the thinness of the laptop computer shell, but it still cannot meet people's pursuit of thin and light laptop computer shells. Utility Model Content

[0003] The utility model aims to provide a sandwich type carbon fiber notebook computer shell which can further meet people's pursuit of lightness and thinness of notebook computer shells in view of the deficiencies in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the sandwich carbon fiber notebook computer shell of the utility model is:

[0005] A sandwich carbon fiber notebook computer shell comprises a foam material layer, wherein a plurality of layers of carbon fiber cloth are arranged on the upper and lower sides of the foam material layer, the carbon fiber cloth and the foam material layer have the shape of a notebook computer shell, and resin and a curing agent are arranged between the carbon fiber cloth and the foam material layer and the adjacent layers of carbon fiber cloth.

[0006] Preferably, the number of carbon fiber cloth layers on the upper and lower sides of the foaming material layer is equal.

[0007] Preferably, the number of layers of carbon fiber cloth on the upper and lower sides of the foaming material layer is two.

[0008] Preferably, the number of layers of carbon fiber cloth on the upper and lower sides of the foaming material layer is three.

[0009] Preferably, the thickness of the carbon fiber cloth is 0.05-0.5 mm, and the thickness of the foaming material layer is 0.2-2 mm.

[0010] Preferably, the textures of adjacent layers of carbon fiber cloth are staggered.

[0011] Preferably, the foaming material layer is a polymethacrylimide layer.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. Since the foam material has good mechanical properties, heat deformation temperature and chemical stability, and its density is much lower than that of carbon fiber composite materials, placing the foam material layer in the middle as a sandwich layer can further reduce the weight of the notebook computer casing and meet people's pursuit of light and thin notebook computer casings.

[0014] 2. The carbon fiber cloth and the foam material layer are pre-formed into the shape of a laptop computer shell, which is convenient for pressing the finished product.

[0015] 3. The number of carbon fiber cloth layers on the upper and lower sides of the foam material layer is equal to ensure that the foam material layer is balanced in force during pressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic structural diagram of a sandwich-type carbon fiber notebook computer housing according to Embodiment 1;

[0017] Figure 2 It is a schematic structural diagram of a sandwich carbon fiber notebook computer housing according to the second embodiment.

[0018] Among them, 1 is a foam material layer, and 2 is a carbon fiber cloth. DETAILED DESCRIPTION

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0020] Embodiment 1, as Figure 1 As shown, a sandwich carbon fiber laptop computer shell comprises a foam material layer 1, the foam material layer is a polymethacrylimide layer, the thickness of the polymethacrylimide layer is 0.4 mm, two layers of carbon fiber cloth 2 are arranged on the upper and lower sides of the foam material layer, the carbon fiber cloth and the foam material layer have the shape of a laptop computer shell, which is convenient for pressing the finished product, the thickness of the carbon fiber cloth is 0.1 mm, the textures of the adjacent layers of carbon fiber cloth are interlaced, and the firmness of the connection between the carbon fiber cloths can be improved, the number of carbon fiber cloth layers on the upper and lower sides is the same, ensuring that the foam material layer is balanced in force during pressing, and resin and curing agent are applied between the carbon fiber cloth and the foam material layer and the adjacent layers of carbon fiber cloth to increase the firmness of the connection between the carbon fiber cloth and the foam material layer and the adjacent layers of carbon fiber cloth.

[0021] Embodiment 2, as Figure 2As shown, a sandwich carbon fiber laptop computer shell comprises a foam material layer 1, the foam material layer is a polymethacrylimide layer, the thickness of the polymethacrylimide layer is 0.5 mm, three layers of carbon fiber cloth 2 are arranged on the upper and lower sides of the foam material layer, the carbon fiber cloth and the foam material layer have the shape of a laptop computer shell, which is convenient for pressing the finished product, the thickness of the carbon fiber cloth is 0.15 mm, the textures of the adjacent layers of carbon fiber cloth are interlaced, and the firmness of the connection between the carbon fiber cloths can be improved, the number of carbon fiber cloth layers on the upper and lower sides is the same, ensuring that the foam material layer is balanced in force during pressing, and resin and curing agent are applied between the carbon fiber cloth and the foam material layer and the adjacent layers of carbon fiber cloth to increase the firmness of the connection between the carbon fiber cloth and the foam material layer and the adjacent layers of carbon fiber cloth.

[0022] The specific working process and principle of a sandwich carbon fiber notebook computer shell: Since polymethacrylimide has good mechanical properties, thermal deformation temperature and chemical stability, and its density (0.05-0.6g / cm 3 ) is much smaller than the density of carbon fiber composite materials (1.4-1.8g / cm 3 ), so placing the foam material layer in the middle as a sandwich layer can further reduce the weight of the laptop computer shell. Compared with the full carbon fiber composite material structure, the utility model can reduce the weight by more than 40% under the condition of the same wall thickness, and can maintain high strength and related performance, thereby meeting people's pursuit of lightness and thinness of the laptop computer shell.
