[0019] Reference Figure 1-3The embodiment of the utility model provides a mobile phone case 100, comprising: a first glass fiber layer 1, a caraf layer 2, and a second glass fiber layer 3 stacked in sequence, wherein the staggered angle between the first glass fiber layer 1 and the caraf layer 2 is greater than 0 degree and less than or equal to 60 degrees, and the staggered angle between the second glass fiber layer 3 and the caraf layer 2 is greater than 0 degree and less than or equal to 60 degrees. By stacking the first glass fiber layer 1, the caraf layer 2, and the second glass fiber layer 3 in sequence, and setting the first glass fiber layer 1, the caraf layer 2, and the second glass fiber layer 3 at a certain staggered angle, the structural stability and strength of the mobile phone case 100 can be enhanced, and the anti-puncture performance of the mobile phone case 100 can be improved, thereby effectively protecting the electronic components inside the mobile phone. In this embodiment, the mobile phone case 100 is also provided with a camera hole 5 and a flash hole 6 for avoiding the installation of a mobile phone camera and a flash.

[0020] Please refer to Figure 1 The first glass fiber layer 1, the caraf layer 2 and the second glass fiber layer 3 are all plain woven structures. The plain woven structure can provide uniform strength distribution and good tensile strength to enhance the overall strength and durability of the mobile phone case 100. Of course, in other embodiments, a twill woven structure or a satin woven structure can also be used.

[0021] The first glass fiber layer 1 has two directions, namely the first direction A1 and the second direction A2. A plurality of first fibers 11 extend along the first direction A1, and they are arranged at intervals from each other in the second direction A2. Similarly, a plurality of second fibers 12 extend along the second direction A2, and they are arranged at intervals from each other in the first direction A1. For example, the first direction A1 is perpendicular to the second direction A2. In some other embodiments, the first direction A1 and the second direction A2 may not necessarily be perpendicular. In this embodiment, the structures of the first glass fiber layer 1, the caraf layer 2, and the second glass fiber layer 3 are the same, except that the material used in the caraf layer 2 is different from that of the first glass fiber layer 1 and the second glass fiber layer 3.

[0022] In this embodiment, the staggered angle between the first glass fiber layer 1 and the caraf layer 2 is 45 degrees, and the staggered angle between the first glass fiber layer 1 and the second glass fiber layer 3 is 0 degrees. That is, before stacking the first glass fiber layer 1 and the caraf layer 2, first straighten and align the positions of the first glass fiber layer 1, the caraf layer 2, and the second glass fiber layer 3, then rotate the caraf layer 45 degrees, and then stack the first glass fiber layer 1 with the caraf layer 2 and the second glass fiber layer 3 in sequence, so as to form a sandwich structure of the first glass fiber layer 1 of 0 degrees, the caraf layer 2 of 45 degrees, and the second glass fiber layer 3 of 0 degrees. Among them, the design of the staggered angle of 45 degrees can further enhance the structural stability of the shell, ensure the close combination between the layers, enhance the anti-puncture effect, and improve the overall strength and durability of the shell. In other embodiments, staggered angles such as 15 degrees, 30 degrees, and 60 degrees can also be used, which can also effectively improve the anti-puncture ability of the mobile phone case 100.

[0023] Furthermore, the thickness of the first glass fiber layer 1 is 0.1-0.25 mm, the thickness of the caraf layer 2 is 0.1-0.15 mm, and the thickness of the second glass fiber layer 3 is 0.1-0.25 mm. Through appropriate thickness design, it can be ensured that the shell is lightweight while maintaining sufficient strength, thereby improving the portability and comfort of use of the electronic device. In this embodiment, the thickness of the pressed mobile phone shell 100 is between 0.4-0.6 mm, which has good puncture resistance and light weight.

[0024] Furthermore, the first glass fiber layer 1 and the second glass fiber layer 3 both include glass fiber and low-temperature curing epoxy resin; the Caraf layer 2 includes aramid fiber and low-temperature curing epoxy resin. The first glass fiber layer 1, Caraf layer 2 and the second glass fiber layer 3 described in the embodiment of the present application are all impregnated with low-temperature curing epoxy resin, which can reduce the temperature requirement of hot pressing during lamination hot pressing molding, saving production costs; wherein, the low-temperature curing epoxy resin is an existing material, and the utility model does not improve the low-temperature curing epoxy resin material. In this embodiment, the molding temperature of the mobile phone case is 150 degrees, and the time is 5-10 minutes. The hot pressing temperature is significantly lower than the existing conventional molding temperature of 170-180 degrees, which is energy-saving and environmentally friendly, and the operation time is correspondingly reduced, thereby improving work efficiency.

[0025] Furthermore, the mobile phone case 100 further comprises: a decorative film layer 4 or an ink texture layer 4, which is disposed on the first glass fiber layer 1 located at the outermost layer of the mobile phone case 100. The addition of the decorative film layer 4 or the ink texture layer 4 can enhance the appearance and protective performance of the shell, and increase the attractiveness and market competitiveness of the product.

[0026] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
