Polymer composites with natural fibres

A new group of materials, consisting of plastic reinforced with natural fibres, offers a broad and very interesting field of application because of their highly promising properties. So-called bio-fibres such as jute, hemp, sisal, kenaf or cotton that once were in obscurity are enjoying a trully renaissance in the high-tech applications last 15 years. Their excellent specific mechanical properties (lightweight) as compared to glass fibres composites (GFC) are the main reason for their popularity: also their relatively low price and the fact that this raw material source is not based on petrochemicals, that makes the fibre production environment friendly (Ecobalance - CO; balance). The field of natural fibres research has experienced an explosion of interest, particularly with regard to its comparable properties to glass fibres within composites materials.

Coraz większą popularnością cieszy się na świecie nowa grupa materiałów wytwarzanych z polimerów syntetycznych z dodatkiem włókien naturalnych takich jak: juta, konopia, sizal, len. kenaf. Ich wspaniałe właściwości (lekka waga) w porównaniu z włóknem szklanym są głównym czynnikiem zwiększającym ich popularność. Również stosunkowo niska cena i fakt ze surowiec nie jest oparty na ropie powoduje tak duże zainteresowanie.
