Is the production of FRP antenna radome difficult

The appearance of FRP antenna radome is estimated that everyone has a little impression, most of them are hemispherical shape, and it looks like there is no technical content, so why do you think it is so expensive? First of all, because the price of FRP material is more expensive than other materials, but the weather resistance and wave permeability of FRP determine that it is the preferred material for radome. Secondly, its design process is not simple, and the following is a small edition of Yari to take you to understand its structural design.

One, laminated structure design

The design of laminated structure is particularly important in the design of FRP antenna radome structure, which is related not only to the physical strength of the radome, but also to the transmittance of the radome.

1, diameter less than 300mm For a radome with a diameter less than 300mm, the laminated structure should be 300 grams of alkali-free glass fiber layer +450 grams of alkali-free glass fiber layer, and the finished product thickness is about 1.7mm-2.2mm;

2, diameter greater than 300mm, less than 600mm For this diameter of the radome, the laminated structure should be 300 grams of alkali-free glass fiber one layer +450 grams of alkali-free glass fiber two layers, the thickness of the finished product is about 2.6-3.1mm;

3, diameter greater than 600mm, less than 800mm For this diameter of the radome, the laminated structure should be 300 grams of alkali-free glass fiber two layers +450 grams of alkali-free glass fiber two layers, the finished thickness of about 2.9-3.4mm. It should be noted that the structural design of the FRP radome of this size is different from that of the conventional, in order to increase the strength of its installation position, it is necessary to reinforce the installation flange position, that is, to add a layer of 450 grams of alkali-free glass fiber to the installation flange, so that the thickness of the installation flange is about 3.8-4.2mm. Of course, there are also customers who want to make the thickness of the installation flange about 5mm, then only need to add a layer of 450 grams of alkali-free glass fiber, so that the thickness of the flange will be between 4.7-5.1mm;

4, the diameter of more than 800mm of the glass fiber reinforced plastic radome structure design needs to pay attention to, it can not rely on the support force of glass fiber reinforced plastic itself to complete, because once its thickness is too thick, the wave transmission rate will be exponential decline, and transportation costs will rise straight. At this time, the inside of the radome should be made of stainless steel or aluminum skeleton, and the glass steel cover body is made into a piecewise assembly structure.
