一种高模量玻璃纤维组合物及其玻璃纤维和复合材料
摘要：
本发明提供一种高模量玻璃纤维组合物及其玻璃纤维和复合材料。其中，玻璃纤维组合物各组分的含量以重量百分比表示如下：SiO2为55.7‑58.9％，Al2O3为15‑19.9％，Y2O3为0.1‑4.3％，La2O3为小于等于1.5％，CeO2为小于等于1.2％，CaO为6‑10％，MgO为9.05‑9.95％，SrO为小于等于2％，Li2O+Na2O+K2O为小于等于0.99％，Li2O为小于等于0.65％，Fe2O3为小于1％，TiO2为0.1‑1.5％，重量百分比的比值C1＝Y2O3/(Y2O3+La2O3+CeO2)的范围为大于0.6。该组合物能大幅提高玻璃的弹性模量，还能显著降低玻璃的液相线温度和成型温度，同等条件下大幅降低玻璃的析晶速率和气泡率，特别适合用于池窑化生产低气泡率的高模量玻璃纤维。
摘要（英）：

The invention provides a high-modulus glass fiber composition and glass fiber thereof and a composite material. The glass fiber composition comprises the following components by weight percentage: 55.7-58.9% of SiO2, 15-19.9% of Al2O3, 0.1-4.3% of Y2O3, less than or equal to 1.5% of La2O3, less than or equal to 1.2% of CeO2, 6-10% of CaO, 9.05-9.95% of MgO, less than or equal to 2% of SrO, less than or equal to 0.99% of Li2O+Na2O+K2O, less than or equal to 0.65% of Li2O, less than 1% of Fe2O3, and 0.1-1.5% of TiO2, wherein a scope of the ratio C1=Y2O3/(Y2O3+La2O3+CeO2) with weight percentage is greater than 0.6. The composition can greatly increase the glass elastic modulus and can obviously reduce the glass liquid line temperature and moulding temperature, greatly reduces the crystallization rate and bubble rate of the glass under same condition, and is especially suitable for producing high-modulus glass fiber with low bubble rate in a tank furnace.
