Problems solved by technology

[0007] The purpose of the present invention is to overcome the problem that the existing thinner carbon fiber products cannot eliminate the distortion of the surface texture. The texture here refers to the texture of the carbon fiber woven cloth prepreg itself. The outer layer is carbon fiber woven prepreg, so the molded product is required to retain the original texture characteristics of carbon fiber woven prepreg

Embodiment 1

[0038] Example 1 (appearance layer molded by molding)

[0039] A compression molding method for carbon fiber products with high appearance requirements, the molding principle is referred to figure 1 and figure 2 , the selected carbon fiber prepreg such as image 3 As shown, the regular texture can be seen from it, including the following steps:

[0040] Step 1: Design the appearance layer of carbon fiber products with high appearance requirements; the preform is the remaining structure after subtracting the appearance layer from the carbon fiber products with high appearance requirements;

[0041] Step 2: Design the forming mold of the appearance layer, that is, the appearance layer mold. The cavity depth of the appearance layer mold is based on the thickness of the appearance layer plus the thickness of the buffer layer;

[0042] Step 3: If figure 1 , add silica gel to the appearance layer mold, and vulcanize to form a silica gel layer. The thickness of the silica gel la...

Embodiment 2

[0044] Embodiment 2 (appearance layer vacuum forming)

[0045] A compression molding method for carbon fiber products with high appearance requirements, the molding principle is referred to Image 6 , the selected carbon fiber prepreg such as image 3 As shown, the regular texture can be seen from it, including the following steps:

[0046] Step 1: Design the appearance layer of carbon fiber products with high appearance requirements. The thickness of the appearance layer is 0.3-2.0mm; the preform is the remaining structure after subtracting the appearance layer from the carbon fiber products with high appearance requirements;

[0047] Step 2: Design the forming mold of the appearance layer, that is, the appearance layer mold. The cavity depth of the appearance layer mold is based on the thickness of the appearance layer plus a buffer thickness, and the buffer thickness is 0.5-5.0 mm.

[0048] Step 3: If image 3 , Lay carbon fiber prepreg on the surface of the mold cavity ...

Abstract

The invention relates to a carbon fiber product with a high appearance requirement and a compression molding method thereof.The compression molding method of the carbon fiber product with the high appearance requirement comprises the steps performing decomposition design on the high-appearance-requirement carbon fiber product, wherein the high-appearance-requirement carbon fiber product comprises an appearance layer (or a lining layer) and a preform matched with the appearance layer; carrying out mold pressing on the appearance layer by adopting an appearance layer mold or carrying out vacuum-pumping molding to obtain a cured appearance layer; and then putting the appearance layer and the preform into a forming mold, enabling the appearance layer to be attached to the surface of the preform, performing heating and pressurizing, and performing integrally curing and forming to obtain the carbon fiber product with the high appearance requirement. According to the invention, the quality problems of distortion and wrinkling of surface lines in the compression molding process of the carbon fiber product can be solved, the yield is improved, the scrap rate is reduced, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber molding and processing, in particular to a carbon fiber product with high appearance requirements and a compression molding method thereof. Background technique [0002] In recent years, with the carbon fiberization of products in many industries, carbon fiber products have been widely used. The molding methods of carbon fiber products are different, such as molding, bag pressing, vacuuming, winding, hand lay-up, RTM, etc. These molding methods have their own advantages, and the products used are also different. They are mainly determined according to the characteristics of the products. To consider the price, so the manufacturing cost is also one of the key considerations. At present, most aluminum products are transformed into carbon fiber. After all, carbon fiber products have their unique characteristics, such as low density, high strength, and corrosion resistance. For products with hig...
