Title: Advancement in the Study of 3D Printable Flame Retardant Polyamide 11 Nanocomposites
Authors: William P. Fahy and Joseph H. Koo
Abstract: Several studies have examined the viability of flame retardant (FR) polyamide 11 (PA11) composites with varying levels of success. A comparison on these studies can provide insight into which additives are most effective for enhancing the flammability and mechanical properties of PA11 composites. A FR PA11 review study found that studies that have used tandem composites of multiwalled carbon nanotubes (MWNT) along with nanoclay yielded PA11 composites with desirable UL94 V-0 ratings, as well as high performance in mechanical properties. In this investigation, the tandem MWNT/nanoclay composites were examined along with alumina nanofibers and a new FR additive. The new materials were fabricated with twin-screw extrusion into 1.75 mm filament for the purpose of fused filament fabrication (FFF) additive manufacturing. Characterization for the study included TGA, MCC, UL 94, and tensile testing.
