Engineering material

Glass fibre

Also known as glass fiber, fiberglass

Fibre drawn from glass, in electrical grades such as borosilicate E-glass and stronger structural grades such as S-glass. It is the lowest-cost of the main structural reinforcing fibres.

What Lithoen records

Each claim states how it is known and cites its evidence.

EstablishedE-glass (borosilicate, electrical) and S/S2-glass (magnesia-alumina-silicate, structural).

E-glass, made from borosilicate glass, is the glass fibre identified for electrical applications by its high resistance to current flow, while S-glass and S2-glass are stronger structural glass fibres made from magnesia-alumina-silicate; glass fibre resists chemical and galvanic corrosion and does not conduct electricity.

EstablishedWind blades, boat hulls, consumer products, aircraft secondary structure.

Because it costs less than other reinforcing fibres, glass fibre is used for large structures such as wind blades and boat hulls and for consumer products such as bathtubs and non-structural vehicle panels; on aircraft it is used for secondary structure such as fairings, radomes and wing tips and for helicopter rotor blades.
