Abstract

Nowadays, phosphate glass fibers (PGF) are considered quite competitive respective to conventional glass fibers. This work focus on the development of PGF fibers intended for structural engineering applications such as composite reinforcement for building and automotive fields. For this purpose, two series of phosphate glasses based on 52P₂O₅–24CaO-13MgO-(11-(X+ Y + Z)) K2O-XAL₂O₃-YF₂O₃-ZTiO₂; (X=1; 3; 5, Y=0; 5, Z=0; 1 mol%) were processed and transformed into phosphate glass fibers by melt spinning. The resulting fibers were characterized. XRD analysis confirmed the non-crystalline nature of phosphate glasses. In addition, the substitution of K₂O by Al₂O₃ and by the combination of Al₂O₃, Fe₂O₃ and TiO₂ in the composition of phosphate glass could lead to a significant increase in fiber density from 2,16 g/cm³ to 2,80 g/cm³. The stability of the produced phosphate glass fibers was examined using two methods: weight loss at 37 °C and dissolution kinetics under different pH levels (4, 7, and 12). The results showed that the chemical resistance of the PGF fibers was improved with up to 99 % increase respective to the original formulation. In addition, the mechanical properties of the spinnable phosphate glass manufactured by replacing K₂O oxide by Al₂O₃ oxide were improved, such a substitution led to a maximum tensile strength and modulus of 2668 MPa and 140 GPa, respectively. Therefore, the tensile proprieties were improved by 75 % compared to the original formulation. This comparative study between phosphate glass fibers (PGF) and traditional fibers highlight similar tensile strength but combined to notable enhancements in chemical stability through cation addition, expanding their potential use in composite and biomedical materials. Finally, a correlation analysis of mechanical performances was carried out. It was observed that the results obtained using the statistical methods were consistent with the experimental data.

用于结构工程应用的新型连续磷酸盐玻璃纤维的合成与表征：结构/性能关系

如今，磷酸盐玻璃纤维（PGF）被认为比传统玻璃纤维更具竞争力。这项工作的重点是开发磷酸盐玻璃纤维，用于结构工程应用，如建筑和汽车领域的复合材料加固。为此，基于 52P2O5-24CaO-13MgO-(11-(X+ Y+ Z))K2O-XAL2O3-YF2O3-ZTiO2; (X=1; 3; 5, Y=0; 5, Z=0; 1 mol%)为基础的两个系列的磷酸盐玻璃，通过熔融纺丝加工成磷酸盐玻璃纤维。对所得纤维进行了表征。XRD 分析证实了磷酸盐玻璃的非结晶性。此外，在磷酸盐玻璃的成分中用 Al2O3 替代 K2O 以及 Al2O3、Fe2O3 和 TiO2 的组合可使纤维密度从 2.16 g/cm3 显著增加到 2.80 g/cm3。我们采用两种方法检测了所生产的磷酸盐玻璃纤维的稳定性：37 °C下的失重和不同pH值（4、7和12）下的溶解动力学。结果表明，磷酸盐玻璃纤维的耐化学性比原来的配方提高了 99%。此外，用 Al2O3 氧化物替代 K2O 氧化物生产的可纺磷酸盐玻璃的机械性能也得到了改善，最大拉伸强度和模量分别达到了 2668 兆帕和 140 千兆帕。因此，与原始配方相比，拉伸性能提高了 75%。磷酸玻璃纤维 (PGF) 与传统纤维的对比研究突出了相似的拉伸强度，但通过添加阳离子，化学稳定性显著增强，从而扩大了其在复合材料和生物医学材料中的潜在用途。最后，还对机械性能进行了相关分析。据观察，使用统计方法得出的结果与实验数据一致。
