Embodiment Construction

[0026] figure 1 It is a process flow chart of the preparation method of FRP of the present invention. The preparation method of FRP comprises the steps:

[0027] S1: Stir and mix the thermosetting synthetic resin solution and the modified filler to form the required slurry, and put the slurry into a resin tank, wherein the mass of the filler is 1% to 20% of the mass of the slurry;

[0028] The thermosetting synthetic resin solution may include any one or more of unsaturated polyester resins, epoxy resins, phenolic resins, furan resins, and vinyl ester resins. The thermosetting synthetic resin solution can be added with other auxiliary materials such as initiators, accelerators, flame retardants, solvents, etc. as the case may be.

[0029] Different resin types and dosages can choose different curing systems. In this embodiment, the thermosetting synthetic resin solution is prepared from unsaturated polyester resin, and an imidazole-based curing system or an amine-based curi...

Abstract

The invention discloses a preparation method of glass-reinforced plastic, and a glass-reinforced plastic antenna housing and a preparation method thereof. The preparation method comprises the following steps: mixing a thermosetting synthetic resin solution and a modified filler to form a required slurry, and putting the slurry in a resin tank, wherein the filler accounts for 1-20 wt% of the slurry; drawing out a thrum from glass fiber yarn on a creel, arranging by a thread board, and passing through a slurry-containing resin tank for impregnation; clamping the slurry-impregnated glass fiber yarn with a plurality of glass fiber mats drawn from a mat frame; leading the mat yarn composite into a mold, and heating to cure and mold the mat yarn composite, thereby forming a glass-reinforced plastic product with the same shape as the mold core; and drawing the molded glass-reinforced plastic product out of the mold with a pulling device. The filler is added into the resin to improve the mechanical strength and lower the dielectric loss and cost. Surface modification is performed on the fiber fabric and filler to enhance the binding force between the resin and fiber fabric and between the resin and filler.

Description

technical field [0001] The invention relates to the technical field of metamaterials, more specifically, to a preparation method of FRP, a FRP 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 str...
