Abstract


Polyamide 6.6 reinforced with 30 % glass fiber (PA 6.6 – 30 % GF) are defined by performant mechanical, thermal, and tribological properties. These properties improvement can be achieved by optimizing manufactured extruded profiles. Extrusion process temperature is important for extruded product quality. In this paper the authors proposed to realize a mathematical model for a tensile stress, resulted with the help of ANOVA (Analysis of variance) for a processing temperature in metering zone and forming zone (die zone ). Metering zone and forming zone are the most important for extrusion process. Extruded product temperature optimization increases quality, productivity and productiveness.

Key words: extrusion, reinforced polymers, polyamide, glass fiber short fiber, temperature, optimization
