3. Application in satellite receiving antenna
The satellite receiving antenna is the key equipment of the satellite ground station, and it is directly related to the quality of the received satellite signal and the stability of the system. The material requirements for satellite antennas are light weight, strong wind resistance, anti-aging, high dimensional accuracy, no deformation, long service life, corrosion resistance, and designable reflective surfaces. Traditional production materials are generally steel plates and aluminum plates, which are produced by stamping technology. The thickness is generally thin, not corrosion-resistant, and has a short service life, generally only 3 to 5 years, and its use limitations are getting bigger and bigger. It adopts glass fiber reinforced plastic material and is produced according to SMC molding process. It has good size stability, light weight, anti-aging, good batch consistency, strong wind resistance, and can also design stiffeners to improve strength according to different requirements. The service life is more than 20 years. , It can be designed to lay metal mesh and other materials to achieve the satellite receiving function, and fully meet the requirements of use in terms of performance and technology. Now SMC satellite antennas have been applied in large quantities, the effect is very good, maintenance-free outdoors, the reception effect is good, and the application prospect is also very good.
4. Application in railway antenna
The railway has carried out the sixth speed increase. The train speed is getting faster and faster, and the signal transmission must be fast and accurate. The signal transmission is done through the antenna, so the influence of the radome on the signal transmission is directly related to the transmission of information. The radome for FRP railway antennas has been in use for quite some time. In addition, mobile communication base stations cannot be established at sea, so mobile communication equipment cannot be used. The antenna radome must withstand the erosion of the maritime climate for a long time. Ordinary materials cannot meet the requirements. The performance characteristics have been reflected to a greater extent at this moment.
5. Application in fiber optic cable reinforced core
Aramid fiber reinforced fiber optic cable reinforcement core (KFRP) is a new type of high-performance non-metallic fiber optic cable reinforcement core, which is widely used in access networks. The product has the following characteristics:
1. Lightweight and high-strength: The aramid fiber reinforced optical cable has low density and high strength, and its strength or modulus far exceeds that of steel wire and glass fiber reinforced optical cable;
2. Low expansion: In a wide temperature range, the aramid fiber reinforced optical cable reinforced core has a coefficient of linear expansion lower than that of steel wire and glass fiber reinforced optical cable reinforced cores;
3. Impact resistance and fracture resistance: The aramid fiber reinforced fiber optic cable reinforcement core not only has ultra-high tensile strength (≥1700Mpa), but also impact resistance and fracture resistance. Even in the case of breaking, it can still maintain a tensile strength of about 1300Mpa ；
4. Good flexibility: The aramid fiber reinforced fiber optic cable reinforced core has a soft texture and is easy to bend, and its minimum bending diameter is only 24 times the diameter;
5. The indoor optical cable has a compact structure, beautiful appearance and excellent bending performance, which is especially suitable for wiring in complex indoor environments.
