Mechanical and Structural Properties of Phosphate Glasses

Abstract

Mechanical and structural properties of sodium (NAFP) and zinc (ZAFP) iron-aluminum-phosphate bulk glass and fibers have been investigated. Young's modulus of the fibers was measured by a three-point bending method while the strength was measured by a two-point bending method. In general, the tensile strength of the ZAFP fibers (4.2-7.2 GPa) was higher than the tensile strength of the NAFP fibers (2.8-4.2 GPa). After exposing the fibers to air for 10 days, the strength decreased by 15-34%. The structure of bulk glass as well as fibers, studied by Mössbauer and IR spectroscopy, was very similar for all the compositions studied.
