Please refer to FIG. 1 . FIG. 1 is a flowchart of a method for manufacturing a casing provided by an embodiment of the present application. An embodiment of the present application provides a method for manufacturing a casing, including:

S100, providing a composite material laminated structure, the composite material laminated structure includes a first composite material layer, a second composite material layer and a third composite material layer, the second composite material layer and the third composite material layer are respectively provided in the first composite material layer On both sides of the material layer, the first composite material layer, the second composite material layer and the third composite material layer all include reinforcements and resins, wherein the reinforcements in the first composite material layer are aramid fibers, and the second composite material layer The reinforcements in the layers and the reinforcements in the third composite material layer both include one or more of glass fibers, carbon fibers, and metal fibers.

It should be noted that the composite laminated structure can be used to process and prepare the shell. By setting the reinforcement in the first composite material layer in the middle of the composite laminated structure to be aramid fiber, the aramid fiber can be used to resist the damage. The advantage of strong impact ability can improve the impact resistance of the shell. In addition, because the reinforcement in the first composite material layer is different from the reinforcement in the second composite material layer and the third composite material layer, it can be adjusted by different materials. The combination of reinforcements can improve the impact resistance of the shell; because the shell has a strong impact resistance, it is beneficial to realize the light and thin design of the shell; The reinforcements in the composite material layer are made of low-cost fiber materials such as glass fiber, carbon fiber, and metal fiber, so that the production cost of the shell can be reduced.

In addition, the inventor of the present application found in experiments that when aramid fibers are selected for the reinforcement in the second composite material layer and the reinforcement in the third composite material layer, the outer surface of the obtained shell is relatively rough, and the appearance of The strength is poor. When glass fiber, carbon fiber and/or metal fiber are selected as the reinforcement in the second composite material layer and the reinforcement in the third composite material layer, the outer surface of the obtained shell is smooth and has better performance. Appearance performance.

Exemplarily, the diameter of each monofilament of glass fiber, carbon fiber, aramid fiber, and metal fiber is 5 μm˜10 μm, such as 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, and the like.

Please refer to FIG. 2 , the reinforcement in the second composite material layer 12 may be glass fiber, and the reinforcement in the third composite material layer 13 may be carbon fiber. It can be understood that, by setting the reinforcements in the first composite material layer 11, the second composite material layer 12, and the third composite material layer 13 as different fiber materials, the advantages of multiple fiber materials can be complemented. While enhancing the impact resistance of the casing 100, the casing 100 has better toughness and better mechanical strength.

Exemplarily, when the reinforcement in the second composite material layer 12 is glass fiber and the reinforcement in the third composite material layer 13 is carbon fiber, the thickness of the second composite material layer 12 is greater than the thickness of the first composite material layer 11 , the thickness of the first composite material layer 11 is greater than the thickness of the third composite material layer 13 . It can be understood that since the tensile strengths of carbon fibers, aramid fibers and glass fibers decrease in turn, the thicknesses of the third composite material layer 13, the first composite material layer 11 and the second composite material layer 12 are gradually increased. The tensile strengths of the first composite material layer 11 , the second composite material layer 12 , and the third composite material layer 13 can be balanced, and problems such as deformation caused by inconsistent tensile strengths of the composite material layers can be eliminated or reduced.

When both the reinforcements in the second composite material layer 12 and the reinforcements in the third composite material layer 13 are glass fibers, the thickness of the second composite material layer 12 and the thickness of the third composite material layer 13 may both be greater than those of the third composite material layer 13. The thickness of a composite material layer 11 , for example, the thickness of the second composite material layer 12 is equal to the thickness of the third composite material layer 13 . It can be understood that since the tensile strength of the glass fiber is lower than that of the aramid fiber, the thickness of the second composite material layer 12 and the thickness of the third composite material layer 13 are set to be greater than those of the first composite material layer 11 . It can balance the tensile strength of the first composite material layer 11, the second composite material layer 12, and the third composite material layer 13, and eliminate or reduce the deformation caused by the inconsistent tensile strength of each composite material layer.

Exemplarily, when the reinforcements in the first composite material layer 11 are aramid fibers, and the reinforcements in the second composite material layer 12 and the reinforcements in the third composite material layer 13 are both glass fibers, the first composite material The thickness ratio between the material layer 11 , the second composite material layer 12 and the third composite material layer 13 may be 1:(1.1-1.5):(1.1-1.5), for example, 1:1.1:1.1, 1:1.2:1.2 , 1:1.3:1.3, 1:1.4:1.4, 1:1.5:1.5, etc.

It can be understood that, since the tensile strength of the aramid fiber is lower than that of the carbon fiber, the thickness of the second composite material layer 12 and the thickness of the third composite material layer 13 are both smaller than those of the first composite material layer 11 . The thickness can balance the tensile strength of the first composite material layer 11, the second composite material layer 12, and the third composite material layer 13, and eliminate or reduce problems such as deformation caused by inconsistent tensile strength of each composite material layer.

Exemplarily, when the reinforcements in the first composite material layer 11 are aramid fibers, and the reinforcements in the second composite material layer 12 and the reinforcements in the third composite material layer 13 are both carbon fibers, the first composite material The thickness ratio between the layer 11 , the second composite material layer 12 and the third composite material layer 13 is 1:(0.5-0.9):(0.5-0.9), for example, 1:0.9:0.9, 1:0.8:0.8, 1 :0.7:0.7, 1:0.6:0.6, 1:0.5:0.5, etc.

When the reinforcements in the three composite material layers 13 are of the same kind of fiber material, it is equivalent to the symmetrical design of the entire composite material laminated structure 10. Since the thermal shrinkage rate of the same kind of fiber material is the same, the composite material laminated structure 10 is heated After being pressurized, the obtained casing 100 has a good molding effect.
