Since 1996 the Nova-Institut has been surveying data on the use of natural fibres (NF) in the German automotive production. In a comprehensive investigation by means of e-mail questionnaires and telephone interviews, the data for the years 2004 and 2005 were surveyed in the summer half-year of 2006. The use of natural fibres (NF) in the German automotive production has further increased also in the years 2004 and 2005 - even though merely with slowed growth rates of less than 3 %. This growth is primarily based on the rising use of the press flow-moulding and injection moulding technique, while the established compression moulding is stagnating. In 2005, for the first time 19,000 t of natural fibres were used in automotive composites. At the same time the shares of natural fibres used have changed. The predominance of flax fibres (market share of almost 65 %) becomes clear which are almost exclusively produced in Europe, in most cases as by-product of textile long fibre production. Hemp fibres, also almost exclusively from European production, presently show a market share of just under 10 %. Larger shares are possible not until further processing capacities will be established or the hemp insulation material market will decrease. Like in recent years, compression moulding is dominant, though slightly less than previously. The share of the compression moulding technique amounted to more than 99 % in recent years, now it has decreased to 95 %. For the first time - for the use of natural fibres - new techniques can be observed: press flow-moulding and injection moulding. Regarding the future market development of natural fibre reinforced composites, there presently isn't any clear trend noticeable. Estimates are wide apart within the automotive branch. NF compression moulding is an established and proven technique for the production of extensive, lightweight and high-class interior parts in medium and luxury class cars. So far only a few companies have dealt with the topic of NF press flow-moulding. A favourable political framework could help biomaterials experience considerable growth. For example forced measures for the reduction of CO2 emissions are to be mentioned here. In this sector, particularly natural fibres can score well, the production of which is ten times less energy-intensive than the one of glass fibres. (Bilingual document: French/English)
