Problems solved by technology

However, no matter how the structure is changed, the smell and dust are too large during the production and repair of FRP radome with FRP, which will cause great harm to the body of the production staff.
Most of the glass fiber reinforced plastic radome adopts hand lay-up process, the curing time of the glass steel plate is generally 1-2 days, the workload is heavy, and the production efficiency is low

Abstract

The invention discloses a radar radome, which is a cover body formed by splicing thermoplastic lightweight composite plate shells. The invention also discloses a method for preparing the above-mentioned radome, which includes the following steps: placing the first layer of continuous glass fiber reinforced thermoplastic resin composite material, the glass fiber / resin mixed felt layer, the second layer of continuous glass fiber The reinforced thermoplastic resin composite material is hot-press formed into a thermoplastic light-weight composite plate shell, and the thermoplastic light-weight composite plate shell is trimmed and spliced ​​to form a cover body. The product of the invention adopts continuous glass fiber reinforced thermoplastic resin composite material as a panel, and has high mechanical strength; the glass fiber / resin mixed felt layer has low density, high porosity and high wave transmittance.

Description

technical field [0001] The invention belongs to the technical field of radar antenna accessories, and relates to a radar antenna accessory and a preparation method thereof. Background technique [0002] The radar antenna signal receiving device is a kind of precision instrument and equipment, which is generally placed outdoors and is easily affected by harsh external environments, such as rain, snow, hail, strong sunlight, etc. If the radar antenna device is exposed to such an environment for a long time, it will seriously interfere with or even cause damage to the function of the radar antenna to receive signals. Therefore, when the radar antenna is installed and used, a radar radome is often installed to protect the radar antenna device. [0003] At present, the widely used radome is a truncated spherical cover assembled from pressed glass steel plate and steel skeleton. FRP radome has the advantages of high mechanical strength, corrosion resistance, good electrical insu...
