Problems solved by technology

However, because the inflated nylon bag is easily deformed after being stressed, the shape and wall thickness of the product after molding are often unsatisfactory, and because the nylon long bag has no elasticity, it affects the internal forming of the carbon fiber product, and the wall thickness is often uneven Therefore, the use of nylon long bags is only easy to form simple tubular or arc-shaped shell products, and it is not easy to produce multilateral tubular products and special-shaped internal hollow shell products. Such products usually require more complicated processes and higher production costs. , and the product is not ideal, which affects the application of carbon fiber products

Embodiment 1

[0035] Embodiment 1, as shown in Fig. 1 and Fig. 2, a method for making a special-shaped shell product that is convenient to form carbon fiber according to the present invention includes the following steps:

[0036] Step a1. Using polystyrene material to make a solid body 1 slightly smaller than the shape of the product;

[0037] Step a2. Molding the two air nozzles 11 together with polystyrene material on the solid body 1;

[0038] Step a3. Using the solid body 1 as an inner mold, spray high-temperature-resistant silica gel on the outer surface of the inner mold, and form a silica gel film layer 2 coated on the solid body; the silica gel film 2 is coated on the inside of the tuyere 11 mouth;

[0039] Step a4. Evenly coating the carbon fiber sheet on the outer surface of the silica gel membrane 2 to form a carbon fiber layer 3 with a certain thickness;

[0040] Step a5. Put the inner mold uniformly coated with the carbon fiber layer 3 into the mold and heat the mold, and th...

Embodiment 2

[0046] Embodiment 2, a kind of manufacturing method of the present invention that is convenient to use carbon fiber to form special-shaped shell products, comprises the following steps:

[0047] Step a1. Using sponge material to make a solid body slightly smaller than the shape of the product;

[0048] Step a2. forming the air nozzle and the sponge material on a solid body;

[0049] Step a3. Using the solid body as the inner mold, spraying high-temperature-resistant silica gel on the outer surface of the inner mold, and forming a silica gel film layer coated on the solid body; the silica gel film is coated on the inner mouth of the tuyere;

[0050] Step a4. Evenly coating the carbon fiber sheet on the outer surface of the silica gel membrane to form a carbon fiber layer with a certain thickness;

[0051] Step a5. Put the inner mold evenly coated with carbon fiber layer into the mold and heat the mold, and the solid body made of sponge material shrinks after being heated;

Embodiment 3

[0054] Embodiment 3, as shown in Fig. 1 and Fig. 2, a manufacturing method of the present invention which is convenient to use carbon fiber to form special-shaped shell products, the difference from Embodiment 1 is that between step a6 and step a7 It also includes step a61. Use the air nozzle 11 as the water nozzle, connect the water source to the inlet of the water nozzle 11, and pour water inward through the water nozzle 11, so that the water flows between the film layer and the solid body. This method can quickly cool down and improve production efficiency.

Abstract

The invention discloses a manufacturing method which is favor of using carbon fiber to form special-shaped shell. Foaming material with thermal shrinkage characteristic is adopted to prepare solid body, which is smaller than the product figure. Wind mouth is formed on the solid body and glue material with high temperature characteristic and no bonding with carbon fiber is coated on the outer surface of solid body to form a glue film layer. After carbon fiber layer is coated uniformly on the surface of glue film it is set in die to obtain carbon fiber special-shaped product. The invention is provided with simple preparation, low cost, easy formation for special-shaped product so as to lessen weight and increase density. The intensity of product with the same weight can be increased by 20%-40% and it is formed easily. It can satisfy the demand of preparing products with different figures.

Description

technical field [0001] The invention relates to a method for making a carbon fiber product, in particular to a method for making a special-shaped shell product with carbon fiber. Background technique [0002] Carbon fiber material has the characteristics of light weight, high strength and good elasticity. Its deformation and rebound ability, energy absorption and release efficiency are better than natural wood fibers, and its tensile capacity is several times higher than steel wire. Because of the high tensile strength, Young's modulus, and excellent heat resistance of carbon fiber, it is widely used in aerospace, aviation, chemical industry, electronics, sports equipment, leisure sports and other fields, from fishing rods, tennis rackets, badminton It is widely used in sports and entertainment products such as rackets and bicycles, various industrial machines, X-ray related medical equipment, civil engineering, aerospace and other fields. The biggest advantage of carbon f...
