Abstract

PURPOSE: To obtain a glass composition for a filament comparable to E-glass in spite of the low B2O3 content and capable of reducing the occurrence of fiber breakage during spinning by specifying the percentage of each of SiO2, B2O3, Al2O3, Cao and R2O as essential components.
CONSTITUTION: This glass composition for a filament contains, by wt., 53W57% SiO2, 3.0W5.8% B2O3, 13W17% Al2O3, 25.3W27% CaO and 0.2W1% R2O as essential components and further contains ≤2% TiO2, ≤1% BaO, ≤2% MgO, ≤0.6%F, ≤0.6% Fe2O3 and 0.5% ZrO2. The B2O3 content of this composition is made as low as possible while satisfying the meltability, water resistance, etc. The occurrence rate of fiber breakage especially during spinning is low, and the composition has characteristics enabling enhanced productivity, etc.
