Radar

Protective radome covers installed on radar antennas on ships, aircraft, and ground stations must withstand harsh weather conditions while allowing electromagnetic waves to pass through with minimal attenuation. The ideal material for this application is FRP composite with polyester or epoxy resin and E-glass or quartz fibers. The manufacturing process is done by hand lay-up or vacuum bag molding.

Resins used in radomes must have a low dielectric constant (below 4) and low loss tangent to avoid attenuating the radar signal. Additionally, resistance to UV radiation, acid rain, and temperature fluctuations (-40 to +80°C) is essential. Alborz Organic Materials Company supplies high-purity specialty resins with optimal dielectric properties for radome applications in defense and telecommunications industries.
