Abstract
The invention discloses alkali-free glass fiber yarn. The alkali-free glass fiber yarn comprises the following chemical components, by weight: 57-60% of SiO2, 1.5-3.5% of TiO2, 8-10% of Al2O3, 2-3% of Fe2O3, 15-20% of CaO, 1.5-2.5% of LiO2, 2.5-3% of MgO, 0.5-1.5% of Na2O, 0.5-1.5% of K2O, 0.2-0.5% of CeO2, and 0.1-0.5% of GeO2. The total of the weight percentages of the components is 100%. The glass fiber provided by the invention has a high modulus of elasticity. A glass fiber product has high rigidity, good acid resistance and good insulation properties.
Description
Technical field
The present invention relates to technical field of inorganic nonmetallic materials, particularly relate to a kind of alkali-free glass fibre yarn.
Background technology
The Young's modulus of E glass both domestic and external, E-CR glass is respectively 72Gpa, 80Gpa.Few more than 86Gpa of the Young's modulus of glass fibre.Compared with common alkali free glass fibre, high-strength high-modulus glass fiber has the premium propertiess such as tensile strength is high, Young's modulus is high, shock resistance is good, chemical stability is good, fatigue resistance is good, high temperature resistant, the field to composite property requirement harshness such as space flight, aviation, weapons can be widely used in, as produced the large component composition materials such as fan blade.But meanwhile, the production difficulty of high-strength high-modulus glass fiber is larger, and production cost is higher, limits it and applies on a large scale.
The Young's modulus of glass fibre and glass form, structure is closely related, and that is, the one-tenth of glass is grouped into the Young's modulus determining this glass fibre, meanwhile, and the good formation of bad influence composite material interface of gum dipping process and the mechanical property of material.It is large to there is fragility in existing glass fiber impregnated glue, and poor toughness, affects pulling force, the problems such as easy oxidation stain, is only applicable to prepare the lower glass fibre of Young's modulus.
Summary of the invention
