A glass fibre composition comprises (wt.%) SiO2 58-65%, CaO 20-26%, Al2O3 9-17%, MgO 0.5-1%, B2O3 0-5%, F2 0-1%, TiO2 0.1-1%, K2O+Na2O 0-0.8%, Fe2 O3 0.1-0.5%, SO3 0-0.6%, and CaO+MgO 21-27%. Contents of components are based on the following mathematical relationship, 21<(CaO+MgO)/MgO<43. The composition improves mechanical strength, high temperature resistance and chemical stability of the glass fibre; and the glass fibre has fine drawing performance. The materials of the composition have low cost and meet the environmental protection requirements.
