A high-performance glass fiber composition, a glass fiber thereof, and a composite material. The glass fiber composition comprises the following components in percentage by weight: 58.5% to 62.5% of SiO2, 14.5% to 17% of Al2O3, 10.5% to 14.5% of CaO, 8% to 10% of MgO, Li2O having a weight percentage greater than 0.5% and less than or equal to 1%, 0.05% to 1% of Na2O, 0.05% to 1% of K2O, 0.05% to 1% of Fe2O3,and 0.15% to 1.5% of TiO2, wherein the mole percentage ratio C1=Li2O/Al2O3 ranges from 0.105 to 0.22, and the mole percentage ratio C2=MgO/(CaO+MgO) ranges from 0.435 to 0.55. The composition can improve mechanical performance of glass, reduce the viscosity of the glass, crystallization risks and the number of bubbles, and is more suitable for large-scale tank furnace production. |
