Glass fibres have been used as reinforcements for centuries and are still in use today in aircraft parts, automobile bodies, recreational boats, and numerous other consumer products. 

E-glass fibres are the most common type of glass fibres used in composites today due to their good strength properties and low cost. They were originally used when strength and high electrical resistivity were required, and are still used in various electrical devices, although their electrical properties have little importance in most composite applications.
