preparation example Construction

[0027] According to the manufacturing method of the electronic product casing provided by the present invention, in a preferred case, the preparation method includes the following steps,

[0028] Provide more than two layers of carbon fiber cloth with staggered grain directions pre-impregnated with thermosetting resin with a central viewing window;

[0029] Lay the multi-layer carbon fiber cloth in the preheating press mold, preheat and press out the edge around the reserved viewing window, the width of the edge is 0.5-2 mm, and the temperature of the preheating press is 100-180 ℃, the preheating pressure is 1-10MPa;

[0030] Place the transparent window on the edge of the reserved window of multi-layer carbon fiber cloth;

[0031] Cover the edge of the transparent window from the other side of the transparent window with a layer of carbon fiber cloth pre-impregnated with thermosetting resin, which also has a window, to obtain a stacked carbon fiber shell semi-finished produc...

Embodiment 1

[0036] The carbon fiber cloth is made of Toray T300 carbon fiber cloth (thickness is 0.125 mm), the epoxy resin is bisphenol F epoxy resin, and the transparent window is made of flat glass (ultra-thin float glass) of 42.57×32.22×0.57 mm.

[0037] 1. Preparation of carbon fiber shell

[0038] In a prepreg machine (Khosla, CD-8048), pre-impregnate two sheets of carbon fiber cloth with epoxy resin for 1 minute at room temperature, and pre-impregnate carbon fiber cloth with a pre-impregnated amount of 45% by weight of carbon fiber cloth. Cut it into 100×55 mm, cut out a reserved viewing window of 39.57×29.22 mm in the middle, and then lay it flat in the hot pressing mold with a staggered 45° in the direction of the grain, and preheat and extrude the edge with a width of 1.6 mm. 100°C, the preheating pressure is 3MPa;

[0039] The transparent window is placed on the edge of the reserved window which has been preheated and pressed, and a layer of carbon fiber prepreg with a prepreg...

Embodiment 2

[0047] The carbon fiber cloth is made of Toray T300 carbon fiber cloth (thickness is 0.125 mm), the epoxy resin is bisphenol A type epoxy resin, and the transparent window is made of flat glass (ultra-thin float glass) of 42.57×32.22×1 mm.

[0048] 1. Preparation of carbon fiber shell

[0049] In a prepreg machine (Khosla, CD-8048), pre-impregnate four sheets of carbon fiber cloth with epoxy resin for 1 minute at room temperature, and pre-impregnate carbon fiber cloth with a pre-impregnated amount of 55% by weight of carbon fiber cloth. Cut it into 100×55mm, and cut out a reserved viewing window of 39.57×29.22mm in the middle, and then spread it in the heat-pressing mold at a staggered 30° in the direction of the grain, and preheat the edge with a width of 0.8mm. The temperature is 180℃, and the preheating pressure is 1MPa;

[0050] The transparent window is placed on the edge of the reserved window which has been preheated and pressed, and a layer of carbon fiber prepreg wit...

Abstract

The invention provides an electronic product outer shell comprising a shell body and a transparent window, wherein the transparent window is inlaid on the shell body, and the shell body is formed by hot-pressing at least one carbon fiber cloth layer presoaked by thermosetting resin. The invention also provides a manufacturing method of the electronic product outer shell. According to the electronic product outer shell, because the shell body is formed by hot-pressing at least one carbon fiber cloth layer presoaked by the thermosetting resin, the electronic product outer shell has stronger mechanical strength.

Description

technical field [0001] The invention relates to an electronic product casing and a manufacturing method thereof. Background technique [0002] With the wide application and continuous development of electronic products, the casings of electronic products are also increasingly abundant. At present, electronic product casings are mainly made of metal or plastic. [0003] The metal shell is mostly made of aluminum alloy, magnesium alloy, stainless steel, etc. by stamping. The advantage of the metal shell is that it has a beautiful appearance and a metallic texture, but it increases the weight of the product, and its wear resistance and scratch resistance are poor. [0004] The plastic shell is mostly made of polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate / acrylonitrile-butadiene-styrene (PC / ABS) blended resin and other materials. These materials have the advantage of being low cost, but have poor mechanical strength. Contents of the invent...
