Abstract

Static fatigue measurements have been carried out on silica fibers for telecommunication networks. These fibers were immersed into water at temperatures ranging from 20 degree(s)C to 70 degree(s)C. They were winded around alumina materials, which induced a permanent stress lying between 3.2 and 3.5 GPa. The evolution of failure time with respect to temperature is Arrhenian. We propose a general relation with semi empirical constants, from which the failure time may be calculated as a function of temperature and stress. The n factor and parameters were calculated. The n factor decreases linearly versus temperature while the BS_i^n-2 parameter increases exponentially with respect to temperature. This reflects two different phenomena: the structural relaxation which compensates the external stress and the acceleration of the chemical attack of the water molecules.
