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 prefabricated mold of the carbon fiber antenna surface, the mold is divided into a female mold 9 and a male mold 8;

[0044] Because the face-to-face precision of the carbon fiber antenna is high, so: (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; Exactly female mold 9 and positive mold 8), process two sealing grooves 12 that place ∮ 10 rubber sealing strip 10 along the outer 100mm of the mold cavity. If the seal is not good enough to leak air, the product is easy to be scrapped. Sealing is a critical step in the entire mold making process. According to the size and structure of the product, the mold for producing carbon fiber antenna surfaces uses simple semicircular two seals (see figure 1 ).

[0045] (2) Step (1) mold is polished;

[00...

specific Embodiment 2

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

[0071] 1. Step (6): 4 layers of 3K carbon fiber cloth 11 are sequentially laid on the male mold 8 of the mold in step (5), and the edge of the 3K carbon fiber cloth 11 is reserved for about 100 mm;

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

[0073] 3, step (11): use epoxy resin injection machine 1 to inject epoxy resin and curing agent (ethylenediamine, its content is 10% of epoxy resin quality) from the feeding port of female mold 9, epoxy resin The mixing and injection pressure of the glue injection machine is 4.5 bar, and after 120 minutes of reaction at 30°C, the mold is demoulded to obtain the blank of the carbon fiber antenna surface.

specific Embodiment 3

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

[0075] Step (11): use epoxy resin injection machine 1 to inject epoxy resin and curing agent (hexamethylenediamine, its content is 12% of epoxy resin quality) from the feeding port of female mold 9, epoxy resin glue injection The mixing injection pressure of the machine is 4 bar, and after 135 minutes of reaction at 25 ° C, the mold is demoulded to obtain the blank of the carbon fiber antenna surface.

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.
