Fabrication and Mechanical Analysis of Nanoclay Reinforced PLA Composite Developed by Fused Filament Fabrication
As a type of additive manufacturing (AM), fused filament fabrication (FFF) makes it possible to develop parts in any complex geometry layer by layer. There have been a wide variety of applications and applications for polymer nanocomposites developed and implemented over the years. This work involved the production of polymer nanocomposite via FFF as well as the evaluation of its mechanical properties. Polylactic acid (PLA) as a matrix material and nanoclay (NC) as reinforcement material was used in development of this novel sustainable and biodegradable material. NC was added in 10 and 20 wt% proportion to PLA. The produced nanocomposite parts through FFF were tested for dimensional accuracy, impact as well as ultimate tensile strength. The parts showed significant increases in ultimate tensile strength with the addition of NC. 62% increase in tensile strength was noted for 20 wt% addition of NC in comparison to pure PLA. Impact strength also showed a similar trend. 3.3 J/mm2 was maximum impact energy that was noted for PLA + 20 wt% NC. Dimensional accuracy of the developed parts was also improved with addition of NC. 78% improvement in dimensional stability was noted for maximum addition of NC to PLA.
