摘要
The present invention provides a glass fiber composition, glass fiber and composite material therefrom. The glass fiber composition comprises the following components expressed as percentage by weight: 58-63% SiO 2 , 13-17% Al 2 O 3 , 6-11.8% CaO, 7-11% MgO, 3.05-8% SrO, 0.1-2% Na 2 O+K 2 O+Li 2 O, 0.1-1% Fe 2 O 3 , 0-1% CeO 2 and 0-2% TiO 2 , wherein a weight percentage ratio C1 = (MgO+SrO)/CaO is greater than 1. Said composition greatly improves the refractive index of glass, significantly shields against harmful rays for humans and further reduces glass crystallization risk and production costs, thereby making it more suitable for large-scale production with refractory-lined furnaces.
