Material	Glass fibre
	Glass fibres are made of silicon oxide with addition of small amounts of other oxides. Glass fibres are characteristic for their high strength, good temperature and corrosion resistance, and low price. There are two main types of glass fibres: E-glass and S-glass. The first type is the most used, and takes its name from its good electrical properties. The second type is very strong (S-glass), stiff, and temperature resistant. Used as reinforcing materials in many sectors, e.g. automotive and naval industries, sport equipment etc. They are produced by a spinning process, in which they are pulled out through a nozzle from molten glass (thousands of meter/min).

Price	Glass fibres are very low cost. Their price for weaved mats is about 15 DKK/kg. Price level: December 1997
