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: Figure 7 represents the estimated dissolution rate of annealed and non-annealed degraded fibres after 28 days of dissolution in PBS at 37℃. The estimated dissolution rate of the annealed fibres was lower than the non-annealed fibres. After 28 days of degradation, the estimated dissolution rate of non-annealed P45B0, P45B5 and P45B10 fibres was 2.53 × 10−6, 1.97 × 10−6 and 1.47 × 10−6g cm−2 h−1, respectively. Whereas dissolution rate of 1.49 × 10−6, 1.25 × 10−6 and 8.59 × 10−7g cm−2 h−1 was observed for annealed P40B0, P45B5 and P45B10 fibres. However, for P50B0 and P50B5 fibres, the dissolution rate decreased from 8.28 × 10−6 to 2.96 × 10−6 g cm−2 h−1 and 4.50 × 10−6 to 1.35 × 10−6 g cm−2 h−1 with annealing, respectively.Figure 7.
