High-strength low-expansion-coefficient glass fiber and composite material
The invention provides a high-strength and low-expansion-coefficient glass fiber which comprises the following components in percentage by mass: 60-66.5% of SiO2; 18% to 22% of Al2O3; 0 to 3.0% of CaO; 10 to 15% of MgO; 0.3% to 3% of P2O5; 0% to 0.9% of Na2O + K2O; 0 to 0.6 percent of Fe2O3 (ferric oxide); 0.4 to 2 percent of TiO2; 0.2% to 3% of Y2O3; the content of each component is in percentage by mass, the sum of the content of SiO2 and the content of P2O5 is 61.4-68%, the sum of the content of TiO2 and the content of Y2O3 is 1-4.5%, and the ratio of the content of Y2O3 to the content of TiO2 is 0.1-7.5. The high-strength and low-expansion-coefficient glass fiber provided by the invention is easy to wire-draw and form, and has relatively high strength and relatively low expansion coefficient.
本发明提供一种高强度、低膨胀系数玻璃纤维，包括以下成分，各成分的含量为质量百分比：60‑66.5％的SiO2；18‑22％的Al2O3；0‑3.0％的CaO；10‑15％的MgO；0.3‑3％的P2O5；0‑0.9％的Na2O+K2O；0‑0.6％的Fe2O3；0.4‑2％的TiO2；0.2‑3％的Y2O3；各成分的含量为质量百分比，并且SiO2含量与P2O5含量之和为61.4‑68％，TiO2含量与Y2O3含量之和为1‑4.5％，Y2O3含量/TiO2含量为0.1‑7.5。本发明提供的高强度、低膨胀系数玻璃纤维，易于拉丝成形，且具有较高的强度和较低的膨胀系数。
