Problems solved by technology

The glass fiber three-proof cloth designed in this way has the advantages of fire prevention, water resistance, moisture resistance, corrosion resistance and durability, thereby improving its service life, but the preparation process of the invention is complicated and the cost is high
[0006] At present, most of the domestic glass fiber cloths use alkali-free glass fiber as the base material, and the strength can reach about 3700MPa, but the stiffness of the glass fiber itself is not high, while the carbon fiber is not only as strong as the glass fiber, but also has a high stiffness. Therefore, in aerospace, In industrial fields such as aviation, automobile and shipbuilding, the application of glass fiber is subject to certain restrictions

Abstract

A compound glass fiber fabric comprises a glass fiber, a carbon fiber and an adhesive. The glass fiber and the carbon fiber are woven by a 2.5D weaving method to form the compound glass fiber fabric,so that the compound glass fiber fabric has high strength of the glass fiber and has also high strength of the carbon fiber, the adhesive is sprayed on the surface of each fiber silk, the compound fiber fabric has the fiber silks of 5-8 layers, the thickness of the fabric is 3.3-5.2mm, a warp yarn is the carbon fiber, the fineness of the warp yarn is 10-12K, the density of the warp yarn is 3-5 pieces / cm / layer, the column number of the warp yarn is 100-105, a weft yarn of the compound fiber fabric is the glass fiber, the fineness of the weft yarn is 10-12K, the density of the warp yarn is 3-5pieces / cm / layer, a titanium dioxide film is soaked on the surface of the compound glass fiber fabric, and a photon with high enough energy can be absorbed under light irradiation, so that the glass fiber fabric has an air purification function. The compound glass fiber fabric has the advantages that the fabric is high in strength and rigidity, resistant to corrosion and the like, the fabric has the air purification function, a preparation method is simple, resources are saved, and cost can be reduced.

Description

technical field [0001] The present invention relates to a glass fiber cloth, in particular to a composite glass fiber cloth. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. With the rapid development of the electronics industry, the printed circuit board industry is moving towards high frequency, miniaturization, and thinning. The industry's requirements for glass fiber cloth are also getting higher and higher. In addition to the existing advantages, it is also hoped that It has higher strength, greater corrosion resistance, or other additional ...
