As shown in fig. 3, in one embodiment, the shell 100 includes a fiber layer 120 and a glaze layer 110 covering the fiber layer 120. The shell 100 comprises an outer surface 101 and an inner surface 102 which are arranged oppositely, the fiber layer 120 is positioned on one side of the inner surface 102 of the shell 100, and the inner surface 102 is positioned on the fiber layer 120; the glaze layer 110 is located on one side of the outer surface 101 of the casing 100, and the outer surface 101 is located on the glaze layer 110. The fiber layer 120 is made of a fiber woven cloth and glaze slurry infiltrated into the fiber woven cloth by sintering. The glaze layer 110 is made of glaze material covering the fiber woven cloth by sintering. It is understood that the structure formed by sintering glaze slip in the glaze layer 110 and the fiber layer 120 is an integrally formed structure, except that the density of the structure formed by sintering glaze slip in the fiber layer 120 is less than that of the glaze layer 110 due to the fiber woven cloth, but the characteristics of the integrally formed structure are not affected. The structure of the glaze slurry in the fiber layer 120, which is sintered and formed, forms the "cement" of the shell 100 together with the glaze layer 110, and the fiber woven cloth forms the steel bars of the shell 100, so that the shell 100 has better integrity. The glaze layer 110 does not have the fiber woven cloth, so that the surface of the glaze layer 110 is flat and smooth, and the pattern of the glaze layer 110 is not broken by the fibers in the fiber woven cloth, so that the glaze layer 110 has good decoration to the shell 100. When the thickness of the shell 100 is processed, the glaze layer 110 may be ground or polished without breaking the fiber woven cloth.
The fiber woven cloth may be carbon fiber woven cloth, glass fiber woven cloth, basalt fiber woven cloth 130, or the like. In one embodiment, the fiber woven cloth is basalt fiber woven cloth 130, the basalt fiber woven cloth 130 is made of basalt fibers serving as raw materials and is composed of two groups of vertical basalt fibers, the size of the basalt fibers is 7-14 μm, and the length-diameter ratio is 1: 1000-3000. The basalt fiber has good temperature resistance, and the glaze slip can not be burnt or softened, so that the application condition can be met.

It is understood that the thickness of the basalt fiber woven cloth 130 is limited to 0.1mm to 0.3mm according to the needs of the housing 100 of the electronic device 10 to meet the assembly needs of the housing 100 of the electronic device 10. In other embodiments, the thickness of the basalt fiber woven fabric 130 may be in other ranges, such as 0.001mm to 0.1mm, 0.3mm to 1.0mm, 1.0mm to 2.0mm, and the like, and when the thickness of the structural member to be prepared is thick, two or more layers of the basalt fiber woven fabric 130 may be stacked to prepare a structural member with a thick thickness; the basalt fiber woven cloth 130 can also be coated with glaze slip 140 with a relatively thick thickness to produce the glaze layer 110 with a relatively thick thickness.
The glaze layer 110 is made of glaze slip 140 covering the fiber woven cloth by sintering, and the thickness of the glaze layer 110 is 0.2mm to 0.3mm, and in other embodiments, the thickness of the glaze layer 110 may be in other ranges, such as 0.01mm to 0.2mm, 0.3mm to 1.0mm, 1.0mm to 2.0mm, and so on. The glaze slurry 140 is prepared by ball milling glaze and water. The glaze includes a base and a pigment, and the pigment makes the glaze have corresponding colors, thereby obtaining a gorgeous case 100. The base material comprises 50-70% of silicon dioxide (SiO)2) 10% -20% of alumina (Al)2O3) 5 to 10 percent of sodium carbonate (Na)2CO3) 3% -5% of barium carbonate (BaCO)3) 2% -5% of zirconium oxide (ZrO)2) And 0-5% of the balance of compounds, wherein the balance of compounds comprise zinc oxide (ZnO) and cerium oxide (CeO)2) Boric acid (H)3BO3) Potassium oxide (K)2O) and lithium oxide (Li)2O) is used. The pigment comprises 5-15% of metal oxide, and the metal oxide comprises various types of metals which can be Fe, Co, Cr, Cu, Zn, Ti and Al elementsThe oxide may be a metal oxide of other elements, and is not limited herein. The component of the glaze is favorable for having better bonding force with the basalt fiber woven cloth 130, so that the bonding force between the structure after sintering the glaze slurry and the basalt fiber woven cloth 130 and the bonding force between the glaze layer 110 and the basalt fiber woven cloth 130 are increased, the glaze layer 110 and the basalt fiber woven cloth 130 are not easy to separate, the strength of the shell 100 is increased, and the glaze layer 110 also has better decorative effect.
The structural member, such as the shell 100, includes a fiber layer 120 and a glaze layer 110 covering the fiber layer 120, the glaze layer 110 being located on one side of an outer surface 101 of the structural member, and the fiber layer 120 being located on one side of an inner surface 102 of the structural member. The glaze layer 110 is made of the glaze slip 140 through sintering, and can have a good decorative effect on the structural member. The fiber layer 120 is made of fiber woven cloth and glaze slurry dipped into the fiber woven cloth through sintering, the glaze slurry in the fiber woven cloth and the glaze slurry 140 forming the glaze layer 110 are in an integrally formed structure after sintering, which is equivalent to cement in a structural member, and the fiber woven cloth is equivalent to reinforcing steel bars in the structural member, so that the structural member has better strength. Compare with traditional ceramic structure, the fibre is woven the cloth quality and is lighter, and the structure of this application is under same size with traditional ceramic structure, and the structure weight of this application is less, and intensity is higher. Because the bonding force between the structure after the glaze slip sintering in the fiber layer 120 and the fiber woven cloth is stronger, and the bonding force between the glaze layer 110 and the fiber woven cloth is stronger, and the structure after the glaze slip sintering in the fiber layer 120 and the glaze slip sintering in the glaze layer 110 are an integrally formed structure, the glaze layer 110 is not easy to fall off, pinholes are not easy to appear on the surface of the structural member, and the yield of the structural member is higher. The structure of the present application is relatively low in cost, attractive in appearance, light in weight, and high in strength, thereby reducing the overall weight of the electronic device 10.
In one embodiment, as shown in fig. 4, a method for manufacturing a structural member is provided, comprising the steps of:
