Effect of boron oxide addition on fibre drawing, mechanical properties and dissolution behaviour of phosphate-based glass fibres with fixed 40, 45 and 50 mol% P2O5.
Bottom Line: The mechanical properties of the fibres were found to significantly increase with increasing B2O3 content.Initial loss of mechanical properties due to annealing was found to be recovered with degradation.Both annealed and non-annealed fibres exhibited a peeling effect of the fibre's outer layer during degradation.

Mentions: A comparison of mechanical properties for annealed and non-annealed fibres was made prior to their dissolution study. Figure 2(a) and (b) showed a decrease in tensile strength and an increase in tensile modulus for annealed fibres. For non-B2O3-containing glass fibres, the tensile strength reduced by approximately 45% of the original value (P < 0.001), whilst a reduction of around 60% in the tensile strength was observed for the B2O3-containing glass fibres. After annealing, the tensile modulus for P40B0, P45B0 and P50B0 fibres was seen to increase by 11, 6% and 7%, whereas as a 10, 8% and 7% reduction (P < 0.001) in tensile modulus was observed for P40B5, P45B5 and P50B5 fibres.Figure 2.
