Problems solved by technology

The study found that the DK value of glass beads is generally between 1.2-2.0. If glass beads can be used to modify FRP radome, it can solve the problem of high DK value of existing FRP radome products. The second experiment finally successfully developed the formula and processing method of FRP radome modified with glass beads

Abstract

The invention discloses a fiberglass radome modified by glass beads, which reduces the DK value thereof, and improves the wave penetration performance of the products. The fiberglass radome modified by glass beads is prepared by the following raw materials in weight portion: 100 portions of unsaturated polyester, 2-10 portions of glass beads, 0.5-2 portions of mold release agent, 0.5-2 portions of curing agent and 0.5-2 portions of accelerator.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic radome and a preparation method thereof, in particular to a glass fiber reinforced plastic radome modified with glass beads and a preparation method thereof. Background technique [0002] Due to the advantages of good weather resistance, insulation, light weight, high strength, stable size and high production efficiency, FRP radome has been widely used in many fields such as the protective shell of wireless and mobile communication base station antennas. Those of ordinary skill in the art know that FRP radome is made of glass fiber plus auxiliary materials (dipping materials). Since glass fiber is relatively stable, the modification of FRP radome is generally to modify the auxiliary materials to achieve FRP. The performance requirements of the radome; as can be seen from the relevant content in the FRP pultrusion process disclosed on pages 797-799 of the "Practical Manual of FRP and FRP Products...
