Rheology of Composites with Nature Vegetal Origin Fibers

Conventional materials like glass, wood or metals replacement with polymer materials is still continuing. More simple thus cheaper production is the main reason. However due to high energy and petrochemical prices are polymer prices increasing too. That´s why various kinds of fillers are used to make polymers cheaper. Of course target is to maintain or improve properties of these compounds. In this paper are solved rheology issues of polymers compounded with vegetal origin fibers.
