Title:
GLASS FABRIC AND GLASS FIBER SHEET MATERIAL USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/084897
Kind Code:
A1
Abstract:
Provided are a glass fabric having good strength and a good modulus of elasticity, and a glass fiber sheet material using the same. This glass fabric is obtained by weaving glass yarn, which is formed by bundling glass fibers that have a fiber diameter of 3 to 6 μm and are spun from molten glass, said molten glass being obtained by melting a glass composition serving as a raw material of the glass fibers. The glass fibers have a composition wherein, relative to the total amount, the amount of SiO2 is 57.0 to 63.0 mass%, the amount of Al2O3 is 19.0 to 23.0 mass%, the amount of MgO is 10.0 to 15.0 mass%, and the amount of CaO is 5.5 to 11.0 mass%. The ratio of the amount of MgO relative to the amount of CaO (MgO/CaO) is in the range of 0.8 to 2.0.
