Problems solved by technology

Such as U.S. Patent 3402055, its tensile strength is significantly higher than that of alkali-free glass fiber, but its liquidus temperature is as high as 1471°C, and the temperature of the wire drawing bushing is as high as 1571°C, making production very difficult, which increases the impact of glass liquid on kiln refractory materials. The corrosion of the platinum bushing shortens the life of the platinum bushing and greatly increases its production cost, so it is difficult to popula

Abstract

The invention relates to a high-strength glass fiber which has an excellent mechanical property and a product of the glass fiber. The high-strength glass fiber can serve as an ideal enhancing base material of a high-performance composite material and is applied widely in the fields of windmill blades, space shuttles and the like, which have high requirements for the specific strength and the specific elasticity modulus. The system is characterized in that calcinated aluminum oxide serves as on of the raw materials, impurities in glass compositions are reduced, the diathermancy of molten glass is improved, the energy consumption is reduced, and the stability of glass fiber drawing operation is improved greatly. The glass fiber with the compositions is required to be produced by direct drawing on a specific tank furnace, the electric boosting input energy of the tank furnace accounts for more than 20% of the total energy input, and more than 60% of the electric boosting energy is applied to raw material melting areas. The fiber mainly comprises 56-65 wt.% of SiO2, 18.5-25.8 wt.% of Al2O3, 11.5-23.0 wt.% of RO (RO is sum of CaO, MgO, SrO and BaO), 0.1-1.0 wt.% of CeO2 and 0.1-0.8 wt.% of Li2O.

Description

technical field [0001] The invention relates to a high-strength glass fiber with excellent mechanical properties, which can be used in the field of high-performance composite materials where ordinary glass fibers are difficult to meet the requirements of strength and stiffness. The present invention also relates to high strength fiberglass articles. Background technique [0002] The most common glass composition used to make continuous glass fiber strands is alkali-free glass, which can be used to reinforce resins to obtain composite materials with excellent properties. However, as the application field of alkali-free glass fiber is expanding day by day, the current mechanical properties of alkali-free glass fiber are far from meeting the requirements of light military weapons, aviation parts, special-purpose automobile parts and wind power generation. It is necessary to find composite materials suitable for higher strength, corrosion resistance and high temperature resista...
