Problems solved by technology

[0002] At present, the production and processing of carbon fiber antennas in my country is mainly based on the autoclave process, but the products produced by the autoclave equipment using high temperature and high pressure can meet the design requirements, but there are disadvantages such as high production costs and large production equipment. , resulting in the failure of mass production of autoclave equipment
For the vast majority of developing countries, the price of antennas prepared by using autoclave equipment is difficult to be accepted by consumers, which leads to the fact that satellite communication users are still limited to large enterprises, governments, military and other group users

specific Embodiment 1

[0042] A method for manufacturing a carbon fiber antenna surface, comprising the following steps:

[0043] (1) The mold for prefabricating the carbon fiber antenna surface, the mold is divided into a female mold 9 and a male mold 8;

[0044] Due to the high requirement for the face-to-face accuracy of the carbon fiber antenna, (1) the material of the mold is 45# steel, and its thickness, length and width are determined according to the chord height and size of the carbon fiber antenna surface; It is the female mold 9 and the male mold 8), and two sealing grooves 12 for placing ∮10 rubber sealing strips 10 are processed along the 100mm outside the mold cavity. If the sealing is not good and the air leaks, the product is easy to be scrapped. Sealing is a key step in the entire mold making process. figure 1 ).

[0045] (2) polishing the mould of step (1);

[0046] For manual polishing, first use 320# whetstone to roughly throw the mold to remove burrs; then use 600# whetstone,...

specific Embodiment 2

[0070] It is roughly the same as the specific embodiment 1, the difference is:

[0071] 1. Step (6): Lay 4 layers of 3K carbon fiber cloth 11 on the male mold 8 of the mold in step (5) in turn, and reserve about 100mm on the edge of the 3K carbon fiber cloth 11;

[0072] 2. The thickness of the PVC foam 13 in step (7) is 14.8mm;

[0073] 3. Step (11): inject epoxy resin and curing agent (ethylenediamine, the content of which is 10% of the mass of epoxy resin) from the feeding port of female mold 9 using epoxy resin glue injection machine 1, epoxy resin The pressure of the mixing glue injection of the glue injection machine is 4.5 bar, and the carbon fiber antenna surface blank is obtained after the reaction at 30 ° C for 120 min and demoulding.

specific Embodiment 3

[0074] It is roughly the same as the specific embodiment 1, the difference is:

[0075] Step (11): use the epoxy resin glue injection machine 1 to inject epoxy resin and curing agent (hexamethylene diamine, its content is 12% of the epoxy resin mass) from the feeding port of the female mold 9, and the epoxy resin is injected with glue The mixing pressure of the machine was 4 bar, and the carbon fiber antenna surface blank was obtained after the reaction at 25 °C for 135 min.

Abstract

The invention relates to a manufacturing method for a carbon fiber antenna surface. The manufacturing method comprises the following steps of 1, prefabricating a die; 2, polishing the die; 3, chemically electroplating the die; 4, measuring the precision, and clearing away impurities; 5, coating a demolding agent; 6, paving carbon fiber cloth on a male die; 7, paving PVC foams on the surface of the male die; 8, paving carbon fiber cloth on the surface of the male die; 9, assembling the male die and a female die, and sealing and fastening the male die and the female die; 10, vacuumizing to enable the vacuum degree in the die to be smaller than -0.096MPa; 11, injecting epoxy resin and a solidifying agent from a material inlet of the female die; 12, sticking a layer of glass paper to the outer surface of a blank after the appearance gets through inspection and is qualified; 13, performing perforation and assembling; and 14, obtaining the carbon fiber antenna surface after the product is qualified through inspection. The carbon fiber antenna surface manufactured by the manufacturing method is smooth, and the precision can reach 0.1R.M.S; and due to normal-temperature solidification, energy is saved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of antenna preparation, and in particular relates to a method for manufacturing a carbon fiber antenna surface. Background technique [0002] At present, the process of producing and processing carbon fiber antennas in my country is mainly based on the autoclave process. However, the products produced by the autoclave equipment using high temperature and high pressure can meet the design requirements, but there are disadvantages such as high production costs and large area of ​​production equipment. , resulting in the inability of autoclave equipment to be used in mass production. For the vast number of developing countries, the price of antennas prepared by autoclave equipment is difficult to be accepted by consumers, so that the users of satellite communication are still limited to group users such as large enterprises, governments, and the military.
