Abstract
In this study, graphene nanoplatelets (GNP) (2%, 4%, 6% and 8% by wt.) were incorporated into PA610 matrix via melt compounding using a twin-screw extruder to compensate for the relatively lower mechanical and thermal properties of bio-based PA610 compared to petroleum-based polyamide. Thermogravimetric analysis showed a slight improvement in thermal stability which peaked for the formulation of 6% GNP. Shear-thinning behavior was more severe with the increase in GNP content. Significant improvement in tensile modulus was observed with increment up to 95% for composites with 8% GNP loading. Flexural modulus increased by16% and strength by 9.5% for 8% GNP composites. These results suggest GNP fillers can be used to enhance the mechanical and thermal properties of PA610 for automotive applications.
