Abstract

The invention provides a boron-free glass fiber composition and glass fibers and a composite material thereof, wherein the boron-free glass fiber composition comprises the following components in percentage by weight: 58-60.4% of SiO2, 14-16.5% of Al2O3, 14.1-16.5% of CaO, 6-8.2% of MgO, 0.01-0.5% of Li2O, less than 1.15% of Na2O + K2O, greater than 0.5% of K2O, less than 1.5% of TiO2 and less than 1% of Fe2O3; and the ratio C1=CaO / MgO of the weight percentage is greater than 2 and less than or equal to 2.4. The boron-free glass fiber composition can remarkably reduce the surface tension of glass, improves the mechanical strength and chemical resistant stability of the glass fibers, can effectively inhibit the crystallization tendency of the glass, reduces the liquidus temperature of the glass and is particularly suitable for production of high-performance glass fibers with low bubble rates.

Description

technical field [0001] The invention relates to a boron-free glass fiber composition, in particular to a high-performance boron-free glass fiber composition which can be used as an advanced composite material reinforcement base material, as well as its glass fiber and composite material. Background technique [0002] Glass fiber belongs to inorganic fiber material, and it can be used to reinforce resin to make composite material with excellent performance. High-performance glass fiber is used as a reinforced base material for advanced composite materials, and it is mainly used in aviation, aerospace, weapons, etc. Wehrmacht field. With the advancement of science and technology and economic development, high-performance glass fiber has been widely used in civil and industrial fields such as motors, wind blades, pressure vessels, offshore oil pipelines, sports equipment, and automobiles. [0003] Since the American Owens Corning Corporation (referred to as OC) developed the ...
