1. Application on the radome of communication radar
The radome is a functional structure that integrates electrical performance, structural strength, rigidity, aerodynamic shape and special functional requirements. Its main function is to improve the aerodynamic shape of the aircraft, protect the antenna system from the external environment, and extend the entire system. Life, protect the accuracy of the antenna surface and position. Traditional manufacturing materials are generally steel plates and aluminum plates, which have many shortcomings, such as large quality, low corrosion resistance, single processing technology, and inability to form products with overly complex shapes. The application has been subject to many restrictions, and the number of applications is decreasing. As a material with excellent performance, FRP materials can be completed by adding conductive fillers if conductivity is required. The structural strength can be completed by designing stiffeners and locally changing the thickness according to the strength requirements. The shape can be made into different shapes according to requirements, and it is corrosion-resistant, Anti-aging, light weight, can be completed by hand lay-up, autoclave, RTM and other processes to ensure that the radome meets the requirements of performance and service life.
2. Application in mobile antenna for communication
In recent years, the rapid development of mobile communications has led to a sharp increase in the amount of mobile antennas. The amount of radome used as a protective clothing for mobile antennas has also increased. Batch consistency, etc. In addition, its service life must be long enough, otherwise it will bring greater inconvenience to installation and maintenance, and increase the cost. The mobile radome produced in the past mostly uses PVC material, but this material is not resistant to aging, has poor wind load resistance, short service life, and less and less use. The glass fiber reinforced plastic material has good wave permeability, strong outdoor anti-aging ability, good wind resistance, good batch consistency produced by the pultrusion production process, and a service life of more than 20 years. It fully meets the requirements of mobile radomes. It has gradually replaced PVC Plastic has become the first choice for mobile radomes. Mobile radomes in Europe, the United States and other countries have banned the use of PVC plastic radomes, and all use glass fiber reinforced plastic radomes. With the further improvement of my country’s requirements for mobile radome materials, the pace of making mobile radomes made of glass fiber reinforced plastic materials instead of PVC plastic is further accelerated.
