Composites

Glasses are commonly known to be brittle, and fabrication of glass fibres is a way to produce a glassy material with improved mechanical properties. The good mechanical properties of glass fibres make degradable phosphate glass fibres of interest in the field of biomaterials, for example, fabrication of bone fracture fixation materials such as glass-fibre-reinforced degradable polymers, but also as meshes or woven fibre constructs for tissue engineering or soft tissue replacement. Degradable fracture fixation materials offer the advantage that they can degrade in the body, obviating the need for a second operation to remove hardware.
