A glass composition for glass fiber comprises, by mass percentage in terms of oxide, 60 to 75% SiO 2 , 0 to 10% Al 2 O 3 , 0 to 20% B 2 O 3 , 5 to 15% Li 2 O+Na 2 O+K 2 O, 0 to 10% MgO+CaO+SrO+BaO+ZnO, 0 to 10% TiO 2 and 0 to 10% Zr0 2 . A glass fiber consists of the above glass composition for glass fiber. A process for producing a glass fiber comprises the steps of melting the above glass composition in a heat-resistant vessel and continuously drawing out the molten glass through a heat-resistant nozzle so as to form a glass fiber; coating the surface thereof with a chemical; and continuously reeling the coated glass fiber. A composite material is obtained by compositing the glass fiber with an organic resin. |
