Mechanical Characterization of PC-ABS Reinforced with CNT Nanocomposites developed by Fused Deposition Modelling

Abstract

Fused Deposition Modeling (FDM), a category of Additive Manufacturing (AM) is a versatile form of manufacturing technology that enables the development of the part layer by layer, of any complex geometry. The development and utilization of polymer nanocomposites for has seen a wide range of implementation. The development of polymer nanocomposite by fused deposition technology and evaluation of its mechanical propertieshave been carried out in this study. Polycarbonate (PC) and Acrylonotrile Butadiene Styrene (ABS) are compounded together with carbon nanotubes. Different proportion of Carbon Nano Tubes (CNT) was added as reinforcement at to PC-ABS matrix. Two variations of samples were developed with incremental addition of CNT to PC-ABS. Ultimate tensile strength and impact strength were analyzed for the developed nano composite FDM parts. It was observed that, with the addition of CNT the ultimate tensile strength of the parts increased significantly. Similar trend was seen for impact strength as well.
