Viscosity of As2Se3 Glass During the Fiber Drawing Process

Résumé

The viscosity of As2Se3 glass within the hot zone region of the fiber drawing process was estimated using the actual temperature distribution and standard continuum mechanics equations for a linear viscous material. The obtained values for the shear viscosity lie between 103 and 106 Pa*s and are in good agreement with those extrapolated from bending and penetration tests at a lower temperature. In our condition, neck-down region is to be found almost independent on the drawing rate or on the fiber tension.
