Low Density FRP Radome and Its Production Process

Abstract

The present invention relates to the field of radome, in particular to a low-density glass fiber reinforced plastic radome and its production process, comprising a first protective cover and a second protective cover enclosed in the shape of a hollow water tower, arranged on the first protective cover and the second protective cover The antenna holding rod in the formed hollow water tower-shaped cavity; the first protective cover is provided with a first engaging member, and the second protective cover is provided with a second engaging member corresponding to the first engaging member of the first protective cover, The first engaging part is connected with the second engaging part so that the first protective cover and the second protective cover are detachably connected to form a hollow water tower-like structure, and the surface of the second protective cover is provided with an openable window for easy maintenance ; The high wave-transmitting fiber cloth layer includes a composite core-spun gauze formed by weaving carbon fiber core yarn and glass fiber woven yarn, and a cured resin cured on the outside of the composite core-spun gauze. The FRP of the invention has the advantages of low density, light weight, small dielectric constant, good wave permeability, high mechanical strength and long service life.

Description

technical field [0001] The invention relates to the field of radome, in particular to a low-density fiberglass radome and a production process thereof. Background technique [0002] With the development of modern mobile communication technology, the current mobile communication technology is entering the 5G era. 5G is not a single wireless access technology, nor is it several new wireless access technologies, but a general term for solutions that integrate a variety of new wireless access technologies and existing wireless access technologies. A truly converged network. [0003] As the next-generation mobile communication network, 5G network is also an extension after 4G. It is faster than the current 4G network transmission speed, at least ten times or even hundreds of times the current 4G transmission speed. Tens of Gb per second. The Ministry of Industry and Information Technology of my country is also conducting 5G technology research and development trials, and plans...

AI Technical Summary

Problems solved by technology

[0004] The large-scale application of 5G networks requires the construction of a large number of antennas. Outdoor antennas are usually placed in the open air and are directly attacked by storms, ice, snow, dust, and solar radiation in nature, resulting in reduced antenna accuracy, shortened life, and poor operating reliability.

However, the existing antenna cover does not meet the requirements of stable physical, mechanical, electrical and chemical properties in terms of mechanical properties, the effect of glass penetration cannot achieve the desired effect, and the dielectric constant cannot be reduced while achieving strength
