Natural fiber sources and biobased fiber materials
Description
Besides traditional resources like wood, our research covers a wide range of alternative fiber sources including straw, oil palm trunk or sugar beet pulp. The raw materials are processed by appropriate pulping and/or disintegration techniques and characterized in terms of chemical and structural properties. The high tensile strength of cellulose-based fibers enables biobased fiber materials with excellent mechanical qualities. In such a material, fibers may either serve as the only structural element or as a reinforcing component like in polymer matrix composites. For the preparation of high-performance biobased fiber materials we pursue different concepts ranging from nanocellulose-based materials all the way to densified wood materials in which the natural structure of wood is largely preserved.
