Glass fibre

If long, thin threads are drawn from a glass melt, this produces glass fibres. These technically very flexible fibres are also currently in use as optical fibres, in textile fabrics or as fillers in construction chemistry (in chemical products for construction) and in glass-fibre reinforced plastics. Their excellent properties combined with high cost-effectiveness mean that glass fibre reinforced plastics are among the most important construction materials today.

Pros and cons

  • Inexpensive
  • Alkaline-resistant grades available


  • High density (specific gravity)

Glass fibre
Manufacturing process

Depending on the area of application, glass fibres are drawn from a preform or from a glass tank through heated nozzles. The main component of glass is silicon dioxide. According to the required property profile, other metal oxides are added, such as aluminium oxide, magnesium oxide, beryllium oxide or calcium oxide. These combinations make it possible to produce glass fibres for different requirements, e.g. for very high mechanical requirements, very high temperatures or high chemical resistance. Standard fibres for electrical applications and for plastic reinforcement are mostly made of so-called E-glass (E = Electric).
