Strength of Ge-Sb-Se Chalcogenide Glass Fibers

Abstract

ABSTRACTStrength of Ge-Sb-Se UV-cured acrylate coated chalcogenide glass fibers was measured in various environments using specially designed fixtures for testing in tensile and bending modes. The data are analyzed using Weibull statistics. Humid or water immersion initially lowered the observed strength of these fibers, presumably due to corrosion by the moisture which penetrated the semi-porous coating. However, after the glass surface became wetted, there was no evidence of further strength degradation (over 1.5 months of immersion).
