ABSTRACT
Glass fibres are among the most versatile industrial reinforcement materials known today. A range of glass formulations can be spun into fibres, some of which are specific to the application of the composite. However, E-glass fibres have a good balance of properties and manufacturing cost that they dominate the industrial market. In recent developments, boron-free formulations have been spun into reinforcements with advantageous properties. These reduce the pollution hazard associated
with the volatility of borides during glass melting. Therefore, the composition of E-glass for fibre drawing has moved in the direction of boron-free [1].
