| Abstract Scope |
Phosphate glass fibers (PGF) are emerging as strong alternatives to conventional glass fibers, with promising applications in composite materials for construction, automotive sectors, biomedical fields, and fertilizers. We developed spinnable phosphate glasses using P₂O₅ and CaO as base components, with modifiers like K₂O, MgO, and Fe₂O₃, then transformed them into fibers via melt-spinning. The process is energy-efficient, using 50% less energy than silica-based fibers. PGF showed excellent mechanical properties (tensile strength: 654-2668 MPa) and stability in various aqueous environments. These fibers improved composite matrices' mechanical properties without surface treatment. Additionally, PGF formulations for soil fertilization provided controlled degradation, and for biomedical use, bioactive fibers were developed for scaffolds with controlled degradation in biological environments. |
