Einsatz von Flachs in faserverstaerkten Kunststoffen/Biopolymeren. Teilprojekt 2: Untersuchungen zum Herstellen und Verarbeiten von flachsfaserverstaerkten Kunststoffen Abschlussbericht

Abstract

Flax fiber reinforced plastics can be processed by techniques that are common for glass fibre reinforced materials. Flax fiber/polypropylene compounds were prepared in a co-rotating twin screw extruder using maleic acid anhydride/polypropylene copolymers as a coupling agent. The tensile strength is increased up to 170% compared to the pure matrix material. Mechanical properties of flax fiber reinforced BMC (a thermosetting Bulk Moulding Compound) processed by injection moulding are comparable to those of glass fibre reinforced BMC. Because of the high polarity of its surface the flax fiber shows a strong adhesion to polyurethanes. So flax fibers can simply be processed to reinforced foam using the structural Reaction Injection Moulding technique.
