Manufacturing complex composite parts using the fused filament fabrication process has shown tremendous potential in terms of saving valuable manufacturing time and cost against conventional manufacturing processes. The use of nylon short carbon fiber composite has a wider range of applications, particularly in the development of impact-resisting structural parts in the aviation and automobile domain. In this investigation, the Izod impact characteristics of 3D printed nylon short carbon fiber with the combinational influence of layer thicknesses (0.1 mm, 0.15 mm, and 0.2 mm) and infill density (80%, 85%, 90% and 95%) are investigated and analyzed. Among the combination of various layer thicknesses and infill densities, the impact absorption of the composite specimen with 85% infill density and 0.2 mm layer thickness showed a maximum impact resistance value of 237.4 J/m. Scanning electron micrography is conducted to examine and analyze the fracture surfaces of the printed specimens. From micrograph analysis, it is confirmed that the interfacial gaps in the mesostructure, which enable fiber bridging and contribute to the highest impact resistance, are what cause the localized matrix deformation at the fracture zone.
