Abstract
Bioresorbable glass fibres have been drawn from a phosphate melt with the composition 25·5Na2O.21·4CaO.2SiO2.51·1P2O5. The anisotropy induced during the drawing process has been studied by means of optical birefringence. The results have been correlated with the main experimental parameters of the fibre drawing process, i.e. drawing speed, mass flow, shear stress and hydrostatic pressure. The birefringence increases with the decrease in both diameter and mass flow and it takes the highest values at largest drawing speeds. A linear correlation between the birefringence and the drawing stress applied to the fibre was observed. The maximum birefringences (500–625 nm cm−1) were observed at high drawing speeds and small hydrostatic pressures.
