Abstract
A new technique for direct impregnation of fiber roving with high viscous thermoplastic melt in an extrusion process is presented. The technology is based on the introduction of ultrasound in the melt enclosing a fiber roving. An impregnation nozzle is designed and implemented in a laboratory manufacturing line for production of continuous fiber-reinforced 3D-printing filaments. First assessment of resulting filament quality cover polylactide, polyamide or polyetherimide reinforced with 12K to 24K carbon fiber and a fiber volume content of 50%. Microscope image analysis and tensile testing is used to identify influence of ultrasound treatment on fiber impregnation. The results show great potential of this new technology for good impregnation and improved fiber distribution.
