Abstract: As one of the most commonly used methods of additive manufacturing (AM), fused filament fabrication (FFF) has drawn a great amount of interest commercially as well as academically. The purpose of this study is to develop a flame retardant (FR) polyamide 6/polyamide 66 (PA6/66) nanocomposite with enhanced flammability, thermal, and mechanical properties while simultaneously being fully compatible with commercially available FFF machines. In this study, PA6/66 nanocomposite formulations will be created with varying amounts of FR, Kraton elastomer (K), nanoclay (NC), and multiwall carbon nanotubes (MWNT), then melt compounded via twin-screw extrusion. These formulations will then be characterized using microscale combustion calorimeter (MCC), thermogravimetric analysis (TGA), and UL94 test methods. Finally, three FR PA6/66 formulations will be down-selected and extruded into 1.75mm FFF filaments and used for flammability, thermal, and mechanical properties characterizations of the resulting FR PA6/66 nanocomposites.
