一种高性能玻璃纤维组合物及其玻璃纤维和复合材料制造技术

一种高性能玻璃纤维组合物及其玻璃纤维和复合材料，该玻璃纤维组合物各组分的含量以重量百分比表示为：SiO2 58‑62％，Al2O3 14‑18％，CaO+MgO 20‑24.5％，CaO大于14％，Li2O 0.01‑0.4％，Na2O+K2O小于2％，TiO2小于3.5％，Fe2O3小于1％，F2小于1％，重量百分比的比值C1＝CaO/MgO的范围为C1大于2且小于等于2.6，重量百分比的比值C2＝SiO2/CaO的范围为3.3‑4.3。该组合物能显著提高玻璃纤维的机械强度和软化点温度，降低玻璃的高温粘度，并能有效抑制玻璃的析晶倾向、降低玻璃的液相线温度，适于大规模池窑生产。

A high performance glass fiber composition and its glass fiber and composite materials

A kind of high performance fiber glass composition and glass fiber and composite materials, glass fiber content of the composition of components in weight percentage is expressed as: SiO2 58 62%, Al2O3 14 18%, CaO+MgO 20 24.5%, CaO greater than 14%, Li2O 0.01 0.4%, Na2O+K2O less than 2%, TiO2 less than 3.5%. Fe2O3 is less than 1%, F2 less than 1%, the ratio of C1 weight percentage = CaO/MgO C1 greater than 2 and less than or equal to 2.6, the ratio of C2 by weight percentage = 3.3 SiO2/CaO 4.3. The composition can significantly improve the mechanical strength and softening point temperature of glass fiber, reduce the viscosity of glass at high temperature, and effectively inhibit the crystallization tendency of glass and reduce the liquidus temperature of glass, which is suitable for large-scale pool kiln production.
