Rheological properties of Biocomposites specified for injection moulding
Original language description
This study evaluates a processability of biocomposite materials based on PLA matrix with various contents of natural fibers of animal and plant origin (cotton, hemp and wool). Rheological properties were determined using capillary rheometer that simulates real load of polymer composite melt when processed (injection molding or extrusion technology). Final evaluation includes origin, geometry aspects and concentration of natural fibers together with impact of matrix. The processability of PLA compositeswas also compared to composites based on commonly used synthetic polymers namely PP (semicrystalline) and ABS (amorphous) and reinforced by selected natural fibers. Measured values (MVR) of composites filled by fibers of plant origin verified predictionof increasing melt viscosity with increasing filler concentration. The presence of wool fibers, however, improved the melt flowability of biocomposite system in spite of adverse geometry of fibers.
