Embodiment 1

[0032] Usually, the radome needs secondary processing after forming, but due to the large size of the shipboard large-diameter radome, there are problems of processing difficulty and high processing cost. Therefore, in order to save the processing process, it is of great significance to adopt the method of net size forming . In addition, in order to obtain good electrical performance and the symmetry of the sandwich structure during the design process of the radome, the radome mostly adopts an odd-numbered sandwich structure, and the most commonly used ones are the symmetrical A sandwich structure and the symmetrical C sandwich structure. Below in conjunction with the specific structure of the radome, the method of using the tooling mold for forming the above-mentioned radome will be described. Embodiment 1: A method for forming the net size of a shipboard large-caliber lightweight A sandwich structure radome, including:

[0033] Step 1. Provide glass fiber prepreg, Nomex hone...

Embodiment 2

[0043] Embodiment 2: A method for forming the net size of a shipboard large-caliber lightweight C-sandwich structure radome, including:

[0044]Step 1. Provide glass fiber prepreg, Nomex honeycomb, epoxy film, tooling mold required for radome molding;

[0045] Step 2. Lay the skin according to the requirements, and the thickness of the skin is about 0.5-0.9mm;

[0046] Step 3. Spread a layer of epoxy resin film on the first layer of skin to ensure that the epoxy resin film and the first layer of skin are tightly bonded;

[0047] Step 4. Lay the pre-shaped first layer of honeycomb on the adhesive film. For products whose size exceeds the raw material size of the honeycomb, use the adhesive film to bond the honeycomb splicing to ensure the tight connection between the honeycombs;

[0048] Step 5. Lay another layer of adhesive film on the first layer of honeycomb to ensure that the adhesive film and honeycomb can fit closely;

[0049] Step 6, spread the second layer of skin on ...

Abstract

The invention discloses a tool mold for forming a radome. The tool mold comprises a forming mold (1) and a frame (2). The forming mold (1) is a forming surface of the radome and is located above the frame (2). According to the scheme, in a process of producing the radome by using the tool mold, secondary processing is not needed, so that the radome forming duration is shortened, and the productionefficiency of the radome is improved.

Description

technical field [0001] The invention relates to the field of molds for forming radomes, in particular to tooling molds for forming shipboard large-caliber light-weight sandwich structure radomes. Background technique [0002] Radar is widely used in aviation, aerospace and other fields, and the use of radomes is becoming more and more extensive. The radome protects the antenna and prevents the influence and interference of the environment on the working state of the radar antenna, thereby reducing the power to drive the antenna, improving its working reliability, and ensuring the radar antenna works around the clock. The existence of the radome prolongs the service life of the antenna, simplifies the structure of the antenna, and reduces the weight of the structure. [0003] In the existing radome molding process, the tooling mold used is generally in the form of a full opening. After vacuum curing and molding, the mold is demoulded, and then the edge is subjected to second...
