Glass fiber reinforced plastic antenna housing and preparation method thereof

Abstract

The invention discloses a glass fiber reinforced plastic antenna housing and a preparation method thereof. The glass fiber reinforced plastic antenna housing comprises the following raw materials, by mass, 100 parts of thermosetting synthetic resin, 0.3-1.8 parts of glass bead, 0.6-1.9 parts of release agent and 0.5-4 parts of curing agent. The preparation method includes that a thermosetting synthetic resin solution and the glass beads are stirred and mixed to form required slurry, and the slurry is placed in a resin groove. A yarn end is drawn out from glass fiber yarn on a yarn support, and the glass fiber yarn is arranged through a yarn guiding plate to penetrate through the resin groove containing the slurry to be soaked. A plurality of sheets of glass fiber mats drawn out from a mat support clamp the glass fiber yarn soaked in the slurry. Mat yarn composite is led to a mold and heated to be cured and molded. A molded antenna housing assembly is drawn out from a mold outlet through a dragging device and assembled to form the glass fiber reinforced plastic antenna housing. The glass beads are added in the resin, the mechanical strength is improved, dielectric loss and cost are reduced, and wave penetrating effect is improved. Surface modification processing is conducted on the fiber mats and the glass beads, and bond between the fiber mats and the glass beads is improved.

Description

technical field [0001] The invention relates to the technical field of metamaterials, more specifically, to a glass fiber reinforced plastic radome and a preparation method thereof. Background technique [0002] The scientific name of FRP is glass fiber reinforced plastic. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing material and synthetic resin as a matrix material. Because its strength is equivalent to steel, and it contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, heat insulation and other properties as glass, so it is called "glass fiber reinforced plastic". FRP generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. Due to the large degree of freedom in the selection of raw materials, product struc...
