“…They have not yet been realized as an effective reinforcement fiber, since while presenting good fiber properties and extremely promising initial composite properties, they do not manage to retain their properties for sufficient time for practical applications in aqueous conditions. For example, failure modes switch from brittle to ductile within days of degradation in an aqueous environment, with apparent interlaminar slip and fiber pull out indicating a loss of fiber/matrix interface .…”

Phosphate‐based glass fibers (PGF) are of interest as reinforcements for degradable implants, but have seen limited application due to their rapid loss of strength when subjected to aqueous conditions. Previous studies have utilized heat treatments to improve longer term strength retention at a significant cost to initial strength. In this study, acid etching is used to recover the initial fiber strength after heat treatment and a subsequent coating of polydopamine is applied to provide longer term retention of this recovered strength. After an initial loss of strength after heat treatment (1135 ‐> 509 MPa), an optimized combination of acid treatment and polydopamine coating was able to recover to approximately 85% of the initial strength (969 MPa). The result was significant in comparison to acid treatment (647 MPa) or coating (688 MPa) alone. The combined acid/coating treatment was demonstrated to maintain fiber properties for at least 14 days, although the amount of polydopamine coating was observed to decrease over this period. The approach reported here is of importance as it offers the required step change in degradation performance that is needed for PGF‐reinforced degradable composites.

“…23 In addition, silicate, borate, and phosphate-based GFs have been observed to possess great biological activity, which makes them suitable for the production of fully degradable composites. 24 Notwithstanding, the literature have revealed that the performance of GF reinforced composites is highly dependent on factors such as the aspect ratio of fiber, fiber distribution, fiber content, and fiber-matrix interactions. 25,26 In addition to the shortcomings earlier outlined for PLA, another major issue with its processing is the tendency to degrade during processing as a result of thermal degradation and hydrolysis.…”

Herein, glass fiber (GF) reinforced binary, ternary, and quaternary poly(lactic acid) (PLA) composites were prepared. Toughening, and chain extension of PLA was achieved through the incorporation of impact modifier and chain extender and their concurrent effects on the spectroscopic, crystallization, mechanical, thermal, and thermomechanical properties of the composites were investigated. High mechanical properties of GF influenced the mechanical performance of the composites. However, GF alone could not restrict the chain mobility of PLA due to poor interface and low crystallization activities in the PLA-GF composite. Incorporation of impact modifier and chain extender produced significantly enhanced interaction between GF and PLA. Significantly, the crystallinity, impact strength, and flexural modulus of PLA in the quaternary composite were increased by 58%, 63%, and 66%, respectively. In addition, damping and effectiveness coefficient of the PLA-GF composite were notably reduced by the simultaneous impact modification and chain extension of the reinforced composites.

“…Single filament limits the use of these fibres as they can only be produced as non-woven random or unidirectional fibre mats [24,25]. To overcome this issue and extend application area of PGFs, scale-up manu-facture to multi-filament continuous phosphate glass fibre fabrication needs to be achieved and Zhu et al [26,27] have developed a phosphate glass fibre system P 2 O 5 -B 2 O 3 -CaO-MgO-Na 2 O-Fe 2 O 3 with excellent thermal stability and fibre drawing performance. However, the poor chemical durability of multifilament PGFs in the composite resulted in catastrophic retention of composite mechanical properties during degradation study [27].…”

The previous research has reported the phosphate based glass has potential medical application due to excellent cytocompatibility and controllable degradability. In this study, Six novel phosphate based glass formulations were produced as two glass system 48P 2 O 5-12B 2 O 3-(25-X)MgO-14CaO-1Na 2 O-(X)Fe 2 O 3 (X = 6, 8, 10) and 45P 2 O 5-(Y)B 2 O 3-(32-Y) MgO-14CaO-1Na 2 O-8Fe 2 O 3 (Y = 12, 15, 20) for glass fibre drawing study, whilst five of them were converted to be fibre successfully. The PBG with 20 mol. % B 2 O 3 was difficult to form fibre with stable meniscus due to high viscosity. The mechanical properties of the fibres were found to increase with increasing B 2 O 3 or Fe 2 O 3 content in the glass. The highest tensile strength (1253 ± 92 MPa) was recorded for 48P 2 O 5-12B 2 O 3-15MgO-14CaO-1Na 2 O-10Fe 2 O 3 glass fibres. The assessment of change in mechanical properties of glass fibres was performed in phosphate buffer saline (PBS) at 37°C for 28 days. The mass loss and dissolution rate of glass fibre was reduced with an increase of Fe 2 O 3 content from 6 to 10 mol. % whilst an increase of dissolution rate was observed with increasing B 2 O 3 content. During the degradation period, a huge decrease on tensile strength was observed, and 20 ~ 40 % tensile strength was residual by 28-day. Whereas, no significant change (P > 0.05) in the tensile modulus was revealed.
