Abstract
The invention relates to the technical field of glass fibers, in particular to a high-strength and high-temperature-resistant glass fiber. The high-strength and high-temperature-resistant glass fibercomprises 60.5-64.5% of SiO2, 8.0-11.0% of Al2O3, 12.0-16.0% of CaO, 3.0-6.0% of MgO, 2-5% of Li2O, 0.5-0.9% of ZrO2, 0.8-1.4% of TiO2, 0.3-0.7% of Na2O, 0.2-0.6% of K2O, 0.3-0.5% of Fe2O3, 0.4-0.8% of SiC, 0.5-1.5% of B2O3, 0.5-1.1% of CeO2 and 0.3-0.8% of GeO2. The produced high-strength and high-temperature-resistant glass fiber is high in mechanical strength and mechanical performance, good inchemical stability and thermal stability, excellent in high temperature resistance and widely applicable.
Description
technical field [0001] The invention relates to the technical field of glass fibers, in particular to a high-strength and high-temperature-resistant glass fiber. 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. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fiel...
