The content, given in weight percentage, of each component of the glass fibre composition is as follows: 53-64% of SiO 2 , more than 19% and less than 25% of Al 2 O 3 , 0.05-7% of Y 2 O 3 + La 2 O 3 + Gd 2 O 3 , less than or equal to 1% of Li 2 O + Na 2 O + K 2 O, 10-24% of CaO + MgO + SrO, 1.5-12% of CaO, less than 2% of TiO 2 , and less than 1.5% of Fe 2 O 3 . The composition significantly improves the elastic modulus and the chemical stability of glass, and on this basis, overcomes the problem that traditional high performance glass has a high risk of crystallisation and a high clarification difficulty, and the problem of it being difficult to perform high efficiency tank furnace production. The composition significantly reduces the liquidus temperature and the forming temperature of high performance glass, and under equal conditions, significantly reduces the crystallisation rate of glass. The composition is particularly suitable for the tank furnace production of a high performance glass fibre having excellent chemical stability.
