Abstract:
Provided are a high performance glass fiber composition, and a glass fiber and a composite material thereof. The content, given in weight percentage, of each component of the glass fiber composition is as follows: 52-67% of SiO 2 , 12-24% of Al 2 O 3 , 0.05-4.5% of Sm 2 O 3 +Gd 2 O 3 , less than 2% of Li 2 O+Na 2 O+K 2 O, 10-24% of CaO+MgO+SrO, less than 16% of CaO, less than 13% of MgO, less than 3% of TiO 2 , and less than 1.5% of Fe 2 O 3 . The composition significantly improves the mechanical properties and the thermal stability of glass, significantly reduces the liquidus temperature and forming temperature of 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 fiber having excellent thermal stability.
