Technical Field

[0001] The invention relates to the technical field of glass fiber processing, in particular to a glass fiber processing technology. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and a wide variety of types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of six kinds of minerals, namely pyrophyllite, quartz sand, limestone, dolomite, colemanite and magnesia stone, through high-temperature melting, wire drawing, winding, weaving and other processes. The different glass fiber processing techniques determine the quality of the glass fiber.

[0003] A Chinese patent discloses a glass fiber processing technology (authorization announcement number CN117466537A). The glass fiber prepared by the patent technology has high tensile fracture strength, improves its fracture toughness, and reduces the possibility of its fracture during use; the deformation temperature and softening temperature deformation temperature are high, reducing the possibility of its deformation in a high temperature environment; the mass loss rate in an acidic environment is low, and the acid resistance is good. However, the above-mentioned glass fiber is completely prepared from raw ore, the raw material cost is high, and the loss of mineral resources is large. The glass melt is directly drawn to complete the production of glass fiber. The strength of the produced glass fiber cannot be guaranteed, which is not conducive to the processing quality of the glass fiber. Therefore, those skilled in the art provide a glass fiber processing technology to solve the problems raised in the above background technology. Summary of the invention

Preparation and molding of composite materials: placing glass fiber fabric in a mold, introducing the mixed polyester resin into the mold for molding, and heat treating the molded glass fiber composite material; S7. Surface treatment and finishing: Polish the surface of the cured glass fiber composite material to improve its appearance quality and smoothness, remove surface defects, and trim and cut the composite material to meet the specifications of the final product; S8.
